                                  PART I

ITEMS 1 AND 2 - BUSINESS AND PROPERTIES

   Union  Oil  Company  of  California  (Union  Oil)  was  incorporated  in
California on October 17, 1890, and is a wholly owned subsidiary of  Unocal
Corporation (Unocal or the Parent).  Virtually all operations of Unocal are
conducted  by  Union Oil which does business as Unocal.  The  terms  "Union
Oil"  and  "the company" as used in this report mean Union Oil  Company  of
California  and  its  consolidated subsidiaries except  where  the  context
indicates otherwise.
   
   Union  Oil  is  a  fully  integrated, high-technology  energy  resources
company  whose  worldwide  operations  comprise  many  aspects  of   energy
production.  The company is principally engaged in the exploration for, and
the  production, transportation and sale of, crude oil and natural  gas  in
the  United  States  and foreign countries; and the manufacture,  purchase,
transportation  and marketing of petroleum and selected chemical  products.
The  company is also engaged in the exploration for, and the production and
sale of, geothermal resources.  Other operations include the production and
marketing of specialty minerals, and real estate development and sales.  In
addition,  the company conducts research programs in support of  the  above
businesses.
   
   Union  Oil  competes  in a challenging business environment  of  global
competition,  political  instability,  rapid  technological  developments,
volatile   oil   and  gas  prices,  and  rising  costs  of   environmental
regulations.   In  order to meet these challenges, the  company  has  gone
through  many changes in recent years.  The company has sold or shut  down
most  businesses  that were marginally related to its core  activities  or
that were not a good strategic fit for Union Oil.
   
   In  1993,  management  developed and implemented  a  ten-year  plan  for
growth  with  a strategy firmly focused on Union Oil's basic  business  and
core  competitive strengths.  The plan focuses on improving cash flow  from
operations   and  strengthening  profitability.   Union  Oil   expects   to
accomplish this plan primarily by increasing energy resource production and
continuing  to  emphasize  cost control and improvement  in  all  areas  of
operations.   During  1993, the company launched a  three-year  development
program to accelerate the production of proved undeveloped reserves in  the
United  States,  primarily in the Gulf of Mexico.   Union  Oil's  long-term
growth  strategy  is  to  expand  its extensive  oil,  gas  and  geothermal
operations  in Southeast Asia.  Union Oil also expects to help develop  the
energy  resources  potential  in the greater  Middle  East,  including  the
Caspian Sea.
   
   The  company  initiated  the  above plan  as  a  result  of  significant
progress  made  toward  meeting the three goals management  established  in
early 1992.  These goals were:  reducing total debt by $1.5 billion by  May
1997;  generating  $700  million  in  after-tax  proceeds  from  sales   of
nonstrategic   assets  by  May  1994;  and  increasing   annual   after-tax
contributions to cash flow by $200 million, also by May 1994.  Since  then,
Union  Oil has reduced its total debt by $1.2 billion, about 80 percent  of
the  way toward the goal.  The company is also 80 percent of the way toward
meeting  its two-year asset sales goal.  At year-end 1993, $560 million  in
after-tax  proceeds were generated from asset sales.  The  third  goal  has
been  accomplished by streamlining business organization and continuing  to
cut   costs,   reducing  staff,  consolidating  offices   and   eliminating
nonessential activities.
   
   During  1993, the company sold its geothermal operations in the Imperial
Valley  of  California, its national auto/truckstop system and  its  retail
agricultural  products  business.  Planned asset sales  in  1994  primarily
include oil and gas properties.
   
   Union  Oil's operations are principally divided into two divisions:  the
Energy   Resources  Division  and  the  Petroleum  Products  and  Chemicals
Division.
   
   The  Energy Resources Division produces crude oil and natural  gas,  and
its  largest  operations are located in Thailand and the Louisiana/Gulf  of
Mexico region.  Other foreign producing locations include Indonesia, Canada
and  the Netherlands.  Union Oil also produces geothermal fluids and  steam
to  generate  power in The Geysers in northern California, the Philippines,
and  soon  on  the  island  of Java in Indonesia.   The  company's  current
business  developments include a gas development project  offshore  Myanmar
and geothermal projects
                                     
                                     1
<PAGE>

on  the  islands  of  Java and Sumatra in Indonesia.   Union  Oil  is  also
pursuing  an  interest  in a Caspian Sea oil development  project  offshore
Azerbaijan.
   
   The  Petroleum  Products  and  Chemicals Division  principally  converts
basic  energy  resources into higher-value products.   Union  Oil  operates
three  refineries  in  California and markets  petroleum  products  in  the
western  United States, Alaska and Hawaii.  Union Oil holds  a  50  percent
interest  in  The  UNO-VEN  Company (UNO-VEN), a  Midwestern  refining  and
marketing   company.    Using  natural  gas  as  feedstock,   the   company
manufactures  nitrogen-based  fertilizers  in  southern  Alaska  to  supply
markets in the western United States and Pacific Rim countries.  Union  Oil
also  produces and markets petroleum coke, lanthanides (rare  earths),  and
specialty graphites.
   
   Union  Oil's net earnings, excluding the effects of accounting  changes,
were $344 million in 1993, up significantly from $197 million in 1992.  The
earnings  increase was primarily due to higher domestic natural gas  prices
and  production,  improved margins for refining and  marketing  operations,
lower  exploration expenses, continued cost reductions, and lower  interest
expense.  These gains were partially offset by lower crude oil prices.  For
a more detailed analysis of the company's financial results and information
on  capital  expenditures, see Management's Discussion and  Analysis  under
Item  7  of  this report.  Financial information relating to the  company's
business  segments, geographic areas of operations, and sales  revenues  by
classes of products is presented under Item 8 of this report.
   
PETROLEUM OPERATIONS

OIL AND GAS EXPLORATION AND PRODUCTION ACTIVITIES

UNITED STATES

   The  company  holds approximately 1.1 million net acres of proven  lands
in  21  states.   Most  of  these lands are located  in  Texas,  Louisiana,
California,  Alaska, Oklahoma, New Mexico, and Montana.  The  company  also
holds  approximately 1.8 million net acres of unproved lands in 26  states.
Most  of  these lands are located in Alaska, Texas, Louisiana,  California,
Colorado,  Michigan, Florida and Wyoming.  Proved and unproved  acreage  in
federal  offshore  exploration and production areas  are  included  in  the
contiguous states.
   
   Union  Oil's domestic crude oil production comes principally from fields
in  Alaska  (27%),  California  (25%), Texas  (19%)  and  Louisiana  (18%).
Approximately 42% of domestic natural gas production is from  offshore  and
onshore  fields  in Louisiana, with most of the balance coming  from  Texas
(22%), Alaska (13%), California (8%), and Oklahoma (4%).
   
   Union  Oil  has varying ownership interests in 26 natural gas processing
plants  located  near major gas fields in the United States.   The  company
operates  12  of these plants and has full ownership in four.  At  December
31,  1993, one plant operated by Union Oil and two plants operated by other
companies were idle.
   
   Most  of the company's crude oil produced in the United States is either
delivered  to or exchanged for crude oil that is processed in the company's
refineries.  A substantial portion of the natural gas produced domestically
is  sold  to  third parties under contracts having a term of at  least  one
year.   Another  large portion of the domestic gas production  is  sold  to
third  parties in the spot market.  The remainder is primarily used in  the
company's chemicals operations or as fuel in its refineries.
   
   The  following  are highlights of Union Oil's domestic  exploration  and
development activities in 1993:
   
   EXPLORATION  ACTIVITIES.  Union Oil's exploration success  rate  in  the
Gulf  of Mexico was 74 percent in 1993, with commercial hydrocarbons  found
in  20  of  the  27  wells  drilled in either unproved  areas  or  untested
formation within proved areas.  The company has been active in the Gulf  of
Mexico  for  more  than  50  years. In recent years,  improved  exploration
techniques  have  revealed new oil and gas resources. In  1993,  Union  Oil
completed  extensive 3-D seismic coverage of its oil and gas  fields  along
the Gulf Coast, yielding new finds in new fault blocks and deeper zones.
                                     
                                     2
<PAGE>
   
   Offshore  Texas,  Union Oil development in the Brazos  A-105  Block  has
brought new life to a field that, after 20 years on production, was nearing
depletion. Development in a new, deeper zone is expected to increase  field
production  to 150 million cubic feet of gas per day by April  1994.  Union
Oil is the operator with a 56.25 percent working interest.
   
   Onshore,  Union  Oil  logged new gas reserves in Fresh  Water  Bayou  in
Louisiana in January 1994.  The discovery well, Louisiana Furs C-16, tested
at  a  daily  rate  of 30.3 million cubic feet of gas and  192  barrels  of
condensate.  The well was drilled to a total depth of 19,260 feet  and  was
completed in a producing horizon below 17,500 feet.  Production is expected
to  begin  in mid-April once natural gas handling facilities are completed.
Union  Oil is the operator and holds a 50 percent working interest  in  the
well.
   
   Union  Oil discovered gas at Felicia Creek in Liberty County, Texas,  in
January  1993  and  brought a second well on production  in  December.  The
field's  daily production averaged 8.8 million cubic feet of  gas  and  660
barrels of condensate in February 1994. Union Oil, the operator, holds a 50
percent  interest in the 2,800-acre Area of Mutual Interest  in  which  the
field is located.
   
   
   DEVELOPMENT  ACTIVITIES.   In 1993, the company  launched  a  three-year
accelerated  drilling  program  to increase  production  of  its  extensive
inventory of proven undeveloped oil and gas resources, primarily  in  North
America.   In  the fourth quarter 1993, the drilling program began  to  pay
off,  with U.S. gas volumes up 10 percent compared with the fourth  quarter
1992.   Increased  gas production in the Gulf of Mexico helped  push  Union
Oil's  U.S.  production above 1 billion cubic feet per day  in  the  fourth
quarter  1993.  Gulf  operations account for  more  than  a  third  of  the
company's  worldwide gas production. In February, daily Gulf production  of
more than 664 million cubic feet of gas was the highest in 12 years.
    

   In  December  1993, Union Oil started production from a well  on  Mobile
Block 904 offshore Mississippi. This is the company's first production from
the  Norphlet trend, a prolific deep gas play. At 22,400 feet, the well  is
one  of  the  deepest Union Oil has drilled in the Gulf  of  Mexico.  Daily
production  averaged 23 million cubic feet of natural gas in  January  1994
and  is  expected  to  increase above 30 million cubic  feet.  Union  Oil's
interest  is  100 percent.  Nearby Mobile Block 861, brought on  stream  in
February 1994, could add 30 million cubic feet per day. The company holds a
25  percent  interest.  Vermilion block 328  (50  percent  interest),  also
brought on stream in February, is expected to produce 24 million cubic feet
per day by June 1994.
   
   Offshore Louisiana, Union Oil has a 50 percent interest in Garden  Banks
191, on stream since November 1993.  This field is expected to produce  160
million  cubic feet of gas per day by October 1994. Union Oil also holds  a
50 percent interest in Garden Banks 189, which achieved peak gas production
of 69 million cubic feet per day in January 1994.
   
   Development drilling will continue in the Chakachatna area of  the  Cook
Inlet (Alaska).  In 1994, four wells are planned to be drilled.
   
   In  central  California,  three 1992 natural gas  discovery  wells  were
placed  on production after the completion of a pipeline.  Union Oil's  two
100  percent-owned wells produced at a combined rate of 10.7 million  cubic
feet  per day after production began during December 1993.  The other well,
a  farmout,  produced at a rate of 3.2 million cubic feet per  day.   Union
Oil's interest in the farmout well will be 34 percent after payout.

FOREIGN

   Union  Oil  conducts  production operations in  six  foreign  countries:
Thailand,  Indonesia, Netherlands, United Kingdom, Canada and  Zaire.   The
company sells most of the natural gas it produces overseas to third parties
under  long-term contracts.  The crude oil and condensate produced overseas
are primarily sold at spot market prices.
   
   THAILAND.   Union Oil began natural gas production in Thailand  in  1981
which  has become a major operation of the company. In February 1994, Union
Oil's  cumulative gas sales from the Gulf of Thailand topped  two  trillion
cubic feet.
                                     
                                     3
<PAGE>
   
   The  company's  fields in the Gulf achieved record production  --  above
800 million cubic feet per day -- in the first half of 1993.  However, that
level  was reduced in July when another company began production  from  the
Bongkot gas field, which also feeds into the main pipeline that carries gas
from the offshore gas fields to Rayong on the country's eastern seaboard.
   
   The  Petroleum Authority of Thailand owns and operates the pipeline. The
decrease  in  Union Oil production has been offset somewhat by the  smaller
Khanom  pipeline,  which  started regular deliveries  of  gas  to  southern
Thailand  in February 1994. The reduced delivery levels will be  eliminated
after  a second major pipeline to Rayong begins operation. The new pipeline
is scheduled for completion in 1996.
   
   The  company's gross production averaged 747 million cubic feet  of  gas
per day and 27,000 barrels of condensate per day in December 1993, and that
rate  is  expected  to  increase  slightly in  1994.  Union  Oil's  working
interests  in the three contract areas in the Gulf of Thailand  average  75
percent.   The  company's operations in Thailand currently have  more  than
1,100  employees  and an average of 1,500 employees of contractors  in  its
natural  gas  operation.  Union Oil and its partners have spent  more  than
$3.6  billion  developing the offshore gas fields.  Spending estimates  for
1994 are approximately $280 million.
   
   Union  Oil will continue to develop its natural gas fields in  the  Gulf
of  Thailand  to  sustain production and prepare for future increases.  The
Jakrawan  field came on production in December 1993, bringing to eight  the
number  of  gas fields Union Oil operates in the Gulf.  Initial tests  from
the  first  production platform indicate that Jakrawan's  daily  production
could peak at 60 million cubic feet of gas and 1,500 barrels of condensate.
Development  of  a  second platform should begin  in  late  1994  when  the
construction of a pipeline is underway.
   
   New  drilling  platforms have been installed in the Erawan  and  Platong
fields.  Appraisal drilling in the Pailin field in the Gulf and exploration
onshore in northeast Thailand continue.
   
   Gas  demand  in Thailand is expected to continue its active growth  over
the  next 10 to 15 years, providing a market for increased production  from
the  Gulf and new supplies from neighboring countries. Union Oil and Total,
the  operator, have completed successful appraisal drilling in  the  Yadana
gas  field  offshore  Myanmar. Negotiations are under way  to  construct  a
pipeline and sell the gas to markets in both Myanmar and Thailand.
   
   INDONESIA.   Union Oil began oil production in Indonesia in  1972  after
the  discovery of the Attaka field.   The field's cumulative oil production
reached 500 million barrels in May 1993.  Through field extensions and  new
discoveries,  Union  Oil  continues to increase the  field's  oil  and  gas
production.   In August 1993, a new platform was set in the  Attaka  field.
Daily  production from the platform averaged 12,000 barrels of  oil  and  8
million  cubic feet of gas by January 1994, boosting Attaka's  total  daily
production by more than 30 percent.  The company's interest in Attaka is 50
percent.
   
   The  new  Serang  field,  12  miles from  Attaka,  began  production  in
December  1993.  The platform was set in 328 feet of water, a record  depth
for  Indonesia.  Production is expected to reach 16,000 barrels of oil  per
day  and 30 million cubic feet of gas per day in 1994. Union Oil's interest
in Serang is 100 percent.

   Exploratory  drilling  is  planned  in  the  southeastern  end  of   the
Indonesian archipelago during 1994.

   CANADA.   Net crude oil production averaged 16,500 barrels  per  day  in
1993,  down  from  17,900  barrels per day in 1992.   Daily  production  of
natural gas was 42 million cubic feet, a 36 percent decrease from the  1992
level.  The decreases were primarily the result of property sales.
   
   Expansion  of  the  gas  storage facility at Aitken  Creek  in  Northern
British  Columbia  continued in 1993.  The facility, the largest  producer-
owned gas storage in Canada, stores gas for delivery when needed to British
Columbia,  the  Pacific Northwest and California.   The  facility  can  now
deliver  250  million cubic feet of gas per day, up from 150 million  cubic
feet per day in 1992.  Aitken Creek handled 36 billion cubic feet of gas in
1993, and the company's share was 16 billion cubic feet.
   
   NETHERLANDS.   Offshore the Netherlands, the new Horizon  oil  field  is
now  producing  a total of 12,700 barrels (gross) daily from  three  wells.
Daily  production is expected to exceed 20,000 barrels in 1994  once  three
additional  wells are drilled. Located in the Dutch North Sea's Block  P/9,
the Horizon platform began production
                                     
                                     4
<PAGE>

in August 1993.  The field was discovered in 1982.  Union Oil's advances in
horizontal   drilling   technology  made  field  development   economically
possible.   Horizontal  wells are more productive than  conventional  wells
because they can access more of the oil-bearing zones.
   
   Gross  production from the other four fields averaged 8,800 barrels  per
day  in  1993,  down  from 10,600 barrels per day in  1992.   The  decrease
reflects continued natural decline of the fields.
   
   Union Oil holds an 80 percent working interest in all five fields.
   
   UNITED KINGDOM.  Gross production from the Heather field averaged  8,100
barrels of oil per day in 1993, a 16 percent decrease from a year ago.  The
field  is  in natural decline and is expected to cease production in  1995.
Union Oil holds a 31.25 percent interest in this field.
   
   ZAIRE.   Gross  production from five fields averaged 16,200  barrels  of
oil  per  day in 1993, compared with 18,900 barrels per day in  1992.   The
decrease was mainly due to natural decline.  Union Oil holds a 17.7 percent
interest in these fields.

FOREIGN EXPLORATION AND OTHER
   
   Union  Oil  pursues  exploration opportunities and business  development
projects  to  sustain  the long-term growth of the company.  The  company's
exploration activity in high-risk, high-potential wildcat areas is  limited
to projects that pass rigorous geo-technical and economic review. Union Oil
has  focused its exploration activities on about 15 trends worldwide.  This
assures  concentration  of  technical talent  and  resources  on  the  most
promising trends with the highest potential value to the company.
   
   Union   Oil's   business  development  group  has   focused   on   other
opportunities  where commercially attractive resources are known  to  exist
and  the  challenge is to develop them effectively. Current  activities  to
market  confirmed gas resources offshore Myanmar and to seek a role in  the
development of significant oil and gas resources in the Caspian Sea reflect
this strategy.
   
   Negotiations  are  ongoing between the Republic  of  Azerbaijan  and  an
international consortium of oil companies of which Union Oil is  a  member.
These  negotiations,  if successfully concluded, represent  major  resource
potential late in the decade.  Although the geologic risk of the project is
minimal  and  the technical challenges of development seem manageable,  the
political   situation  in  the  Caucasus  region  has  not  yet  completely
stabilized. Nevertheless, the region has clear interests in developing  its
major  energy resources and offers many opportunities for Western expertise
and  capital to share the risks and economic rewards. Union Oil is prepared
to  join its partners in the preliminary stages of development once a firm,
commercially attractive agreement with the government is reached.
   
   In  early 1993, Union Oil signed a petroleum exploration agreement  with
the  Republic of Trinidad and Tobago for a frontier block 45 miles off  the
east  coast  of  Trinidad.  Later the company completed  an  extensive  3-D
seismic survey.  The company expects to spend at least $12 million in  1994
to  explore the block.  Union Oil currently holds a 100 percent interest in
the  block, which covers 486 square miles, with an average water  depth  of
300  feet.  Under the terms of the agreement, the company will drill  three
wells.   The company is currently seeking a partner to jointly explore  the
block.
   
   In  Syria the company plans to spend $9 million to drill two exploratory
wells in 1994.
   
   In  light  of the changing political climates and relationships  between
international oil companies and host governments in the foregoing and other
parts  of the world, including changes by producing countries in posted  or
tax-reference  prices  for crude oil, increases  in  tax  rates  (sometimes
retroactively) and demands for increased participation in the ownership  of
operations, it is recognized that there could be changes in the  status  of
Union  Oil's  activities in these and other foreign  countries  during  the

REFINING, MARKETING AND TRANSPORTATION ACTIVITIES

REFINING

   Union  Oil  owns  and  operates  three refineries  in  California.   The
company  also has a 50 percent interest in the Chicago Refinery (Illinois),
which is operated by UNO-VEN.
   
   The  refineries  manufacture a complete line of  high-quality  petroleum
products  and  certain basic chemicals, including automotive  and  aviation
gasolines,  liquefied  petroleum  gases, naphthas  and  solvents,  jet  and
turbine fuels, kerosine, diesel oils, automotive and industrial lubricating
oils,  waxes,  asphalts,  residual fuel oils  and  petroleum  coke.   Rated
capacities  of  crude  oil  processing units for the  four  refineries  are
summarized below.

   The  Carson  plant was purchased in 1991 and was fully  integrated  into
Union  Oil's  refining  system in 1992.  During 1993, additional  pipelines
were completed to interconnect the Wilmington and Carson plants to increase
the  reliability and flexibility of refinery operations.  Also, the company
moved  the main components of a gas-oil hydrotreater from its closed shale-
oil facility in Colorado to the Carson plant.  The company plans to install
the  hydrotreater  during 1994.  The new unit will  increase  hydrotreating
capacity  at  Carson  by nearly 30 percent, thereby boosting  its  gasoline
production.
   
   Union  Oil's California refining system operates in a difficult business
climate,   primarily   because  of  increasingly  stringent   environmental
regulations.    Reformulated   gasoline,  manufactured   to   Environmental
Protection  Agency (EPA) standards, must be available for sale  by  January
1995  in compliance with the Federal Clean Air Act Amendments of 1990.   By
March  1996,  the  more  stringent California Air  Resources  Board  (CARB)
standards take effect in California.  Union Oil will complete EPA  gasoline
manufacturing facilities at its Los Angeles refinery in the fourth  quarter
of  1994.  Construction of facilities to produce CARB gasoline is scheduled
for  completion  at  the Los Angeles and San Francisco refineries  in  late
1995.
   
   Union  Oil expects to spend approximately $210 million in 1994 and  $175
million  in  1995  to  modify  its refineries in  order  to  produce  these
reformulated  fuels.   The goal is to maximize production  of  reformulated
fuels while controlling costs.
   
   In  the third quarter of 1993, Union Oil began producing diesel fuel  to
meet  CARB  requirements.  Through an innovative approach, the company  was
able  to  start  production of the CARB formulation with relatively  modest
capital expenditures.
   
   Union  Oil's  Los  Angeles Refinery only suffered minor  damage  when  a
major earthquake hit Southern California on January 17, 1994.

MARKETING

   Union  Oil markets gasoline and other refined petroleum products in  the
United  States  under  the "Unocal 76" trade name.  Gasoline  is  marketed,
directly  or through jobbers and marketers, to consumers at retail  service
stations.  Substantially all retail outlets, including locations owned  and
leased  by  the company, are operated by independent dealers.   The  retail
outlets   also   sell  branded  tires,  batteries  and   other   automobile
accessories.
   
   In  addition, jet fuels, diesel fuel, lube oil, and heavy fuel  oil  are
marketed   to   commercial   users.   The  company's   crude   supply   and
transportation  group  also markets crude oil  produced  by  Union  Oil  or
purchased from others.
   
   WEST  COAST.   Union  Oil's retail marketing on the  West  Coast  covers
seven  states: California, Arizona, Nevada, Hawaii, Washington, Oregon  and
Alaska.   The company has about a 13.5 percent market share in the  greater
Los  Angeles metropolitan area which represents one of the world's  largest
regional  gasoline markets.  The West Coast marketing network includes  236
wholesale marketing stations and terminals, and approximately 1,500 service
stations.
   
   Over  several  years,  Union Oil has worked  to  strengthen  its  retail
marketing effort.  In October 1993, the company introduced co-branded,  no-
fee Visa and Mastercard credit cards.  Card users earn a one percent rebate
on  all  purchases,  credited  monthly against  purchases  from  Unocal  76
stations.   By March 1994, Associated National Bank of Delaware had  opened
more than half a million co-branded accounts.  Union Oil continues to offer
its  private label card, with 1.4 million active accounts.  Union Oil plans
to  outsource the data processing of its private label credit card program.
Union  Oil  signed  an agreement with First Data Resources  to  handle  the
processing at its center in Tulsa, Oklahoma.  The move is expected to occur
during the second quarter of 1994.
   
   The  company  is  also investing in improved technology at  its  service
stations.   A satellite-based electronic point-of-sale system installed  at
900 stations will speed credit card transactions and reduce their cost.  By
the  end  of 1994, nearly 330 service stations are scheduled to  have  card
readers in the gasoline dispensers.
   
   The  company  continues its low-cost programs to  help  its  independent
dealers  increase station volumes.  These include improving service station
appearance  and  lighting,  and surveying customers  to  identify  ways  to
improve the quality of service.
   
   SOUTHEAST MARKETING AND AUTO/TRUCKSTOPS.  At the end of 1993, Union  Oil
has  substantially completed the phase-out of its marketing  operations  in
the  southeastern  United States.  Union Oil has  lube  oil  terminals  and
blending  operations in Savannah, Georgia, which have been integrated  into
the company's system.
   
                                     9

   In  early  1993,  the  company   completed  the  sale  of  its  national
auto/truckstop  system  to National Auto/Truckstops,  Inc.  (National)  for
approximately $180 million.  The sale included the transfer of 140  branded
facilities  of  which 97 were Union Oil-owned locations.  National  markets
its products under the "76" trade name.
   
   The company's sales volumes of refined products, crude oil and natural
gas liquids, including its equity portion of UNO-VEN, are as follows:

   The decline in sales volume from 1991 was principally due to the phase-
out of the company's marketing operations in the southeastern United States.

TRANSPORTATION

   Union  Oil's  petroleum  supply  and transportation  operations  provide
important  support functions, keeping refineries supplied with feed  stocks
and  transporting products to market.  A substantial part  of  Union  Oil's
crude  oil  production  and  purchases  is  transported  to  the  company's
refineries  or  to selling locations by approximately 8,700  miles  of  raw
material  pipelines which Union Oil owns, wholly or partially,  or  leases.
Union  Oil  also  has  interests in approximately 7,400  miles  of  refined
product pipelines, either owned or through 17 joint venture pipelines.  The
company has a 20.75 percent interest in the Colonial Pipeline Company.  The
Colonial system runs from Texas to New Jersey, and transports a significant
portion of all liquefied petroleum products consumed in its 13-state market
area.
   
   Unocal  Pipeline Company, a wholly owned subsidiary, has a 1.36  percent
participation  interest in the Trans-Alaska Pipeline System  (TAPS),  which
transports crude oil from the North Slope of Alaska to the port  of  Valdez
in  Alaska.  In 1993, TAPS oil throughput averaged 1.7 million barrels  per
day, of which Union Oil's share was approximately 23,000 barrels per day.
   
   Union  Oil's  marine fleet at year-end 1993 consisted of one  crude  oil
tanker,  two refined product tankers and one chemical product tanker.   The
company also has an extensive fleet of product tank trucks.

THE UNO-VEN COMPANY (UNO-VEN)

   UNO-VEN,  a refining and marketing partnership in the Midwest, owns  the
Chicago  Refinery, 12 product terminals, 4 lubricant terminals and  a  lube
oil blending and packaging plant.  UNO-VEN has a long-term crude oil supply
agreement  with a subsidiary of Petroleos de Venezuela, S.A. (PDVSA)  which
provides 135,000 barrels per day of Venezuelan crude as feedstock  for  the
refinery  through the year 2009.  All products produced from  its  refinery
operations  are  marketed  under the "76" trade  name.   UNO-VEN  supplies,
directly  or  through  jobbers and marketers, approximately  2,670  service
stations  and  51  truckstops.   UNO-VEN's  wholesale  marketing  and  bulk
distribution network consists of 250 stations.
   
UNO-VEN is an Illinois general partnership.  The managing general partners,
each with a 50 percent interest, are Midwest 76, Inc., a subsidiary of
Union Oil, and VPHI Midwest, Inc., a Venezuela Petroleum Holdings, Inc.
(VPHI) subsidiary.  VPHI is a subsidiary of PDVSA.

CHEMICALS & MINERALS OPERATIONS

   Union Oil is involved in the production and marketing of agricultural,
carbon and mineral products.  These businesses are divided into two groups
described below.

   AGRICULTURAL PRODUCTS.  This group principally manufactures and  markets
nitrogen-based  fertilizers for wholesale markets.  Union Oil  is  a  major
fertilizer supplier for U.S. farmers west of the Rockies and to the Pacific
Rim markets.

   In  February  1993, the company's wholly owned subsidiary,  the  PureGro
Company,  sold its remaining 33 agricultural retail outlets,  primarily  in
the western United States.

   Union  Oil's primary fertilizer manufacturing plants, located in  Kenai,
Alaska,  produce  ammonia  and  urea for  agricultural  applications  using
natural  gas  as  feedstock.  The natural gas comes primarily  from  nearby
Union Oil-operated fields.  This operation is supported by a system of West
Coast terminals, and product upgrading plants in Kennewick, Washington, and
West Sacramento, California.
   
   Union  Oil's  agricultural products operations  faced  major  challenges
with China's reduction in urea imports and increased exports of ammonia and
urea  from  former Soviet republics.  However, by year-end 1993, production
in  the former Soviet republics was diminishing and markets began to return
to  the  pre-1993  balance.  While domestic markets were  impacted  by  the
international market, Union Oil serves a stable, mature market for nitrogen
fertilizers in the western United States.

   In  May  1993,  Union  Oil completed its first shipment  since  1974  to
Vietnam.   The Kenai plant shipped 18,000 tons of urea, primarily for  rice
cultivation.   This  market  is  expected  to  grow  as  a  result  of  the
normalization of U.S.-Vietnam trade relations announced in February 1994.
   
   CARBON  AND  MINERAL PRODUCTS.  Green petroleum coke,  a  by-product  of
refining  operations, is calcined for use in aluminum production and  other
industrial  applications.  Green sponge coke is also  sold  in  the  United
States  and  overseas  as fuel.  Calcining plants are located  adjacent  to
Union  Oil's Santa Maria and San Francisco refineries and UNO-VEN's Chicago
Refinery.
   
   Petroleum  coke sales were reduced in 1993 because of the  recession  in
the  aluminum  industry.   Increased  coke  sales  for  chemical  reduction
processes and fuel partially offset the decline.
   
   The  Needle  Coker Company, a joint venture equally owned by  Union  Oil
and  UNO-VEN, produces calcined needle coke at facilities adjacent to  UNO-
VEN's Chicago Refinery.  Needle coke is a high quality petroleum coke  used
to  make  graphite electrodes for the production of steel in  electric  arc
furnaces.
   
   Through  its  wholly owned subsidiary, Poco Graphite, Inc., the  company
manufactures   premium   graphite  materials   for   use   in   electrodes,
semiconductors,  biomedical products and other advanced technologies.   The
subsidiary  experienced  its  seventh consecutive  year  of  sales  growth.
Construction is under way to expand the company's manufacturing capacity in
Decatur, Texas.
   
   Union  Oil's  mineral operations are carried out by  Molycorp,  Inc.,  a
wholly  owned  subsidiary, which mines, processes and markets  lanthanides.
It  operates  a lanthanide mine and mill, and a chemical plant at  Mountain
Pass,  California.  Lanthanide elements have a variety of  applications  in
industrial  and  electronic  products,  including  high-strength   magnets,
television phosphors, and auto and refining catalysts.  Lanthanide  markets
have  become  highly competitive over the past 10 years with the  entry  of
suppliers  from  China,  Japan and Eastern Europe.  Molycorp  continued  to
focus its production on high-quality cerium of which demand is growing  for
use in automobile catalytic converters and glass to help filter ultraviolet
radiation.

   Molycorp  also  owns  an  approximate 45 percent  interest  in  CBMM,  a
Brazilian  company which is the world's largest niobium producer.   Niobium
is used as a hardening agent in steel.
   
                                    11
<PAGE>
   
   Operations  have been suspended at Molycorp's molybdenum mine  and  mill
at  Questa  (New  Mexico), its molybdenum roasting facility  in  Washington
(Pennsylvania), and its lanthanide processing facilities at Washington  and
York (Pennsylvania) and Louviers (Colorado).
   
   The company's production of ammonia, processed sponge coke and
lanthanides are as follows:

GEOTHERMAL OPERATIONS

   Union  Oil  is  the  world's largest supplier of geothermal  energy  for
power  generation, with major operations in California and the  Philippines
and  a  new development project in Indonesia.  The production of geothermal
resources for power generation has been a core business for Union  Oil  for
more  than  20  years.  Union Oil's reserves of 125 million  megawatt-hours
represents the energy equivalent of 188 million barrels of oil.   In  1993,
net  geothermal  electricity production from worldwide operations  was  7.3
million  megawatt-hours, the energy equivalent of 10.9 million  barrels  of
oil.
   
   In  1993,  Union  Oil  sold its geothermal operations  in  the  Imperial
Valley  of  California.   The  underlying  geothermal  reserves  sold  only
represented  about  nine  percent  of the  company's  worldwide  geothermal
reserves.
   
   Union  Oil expects to begin supplying steam for power generation at  the
company's  first geothermal development in Indonesia in the second  quarter
of  1994.  Demand for electricity is rapidly increasing in this  nation  of
nearly  200  million  people.  Union Oil currently  has  proven  geothermal
reserves  on the island of Java that represent about 35 million barrels  of
crude  oil  equivalent.   The  company  will  begin  exploration  of   very
encouraging resource prospects on the island of Sumatra in 1994.
   
   In  December 1993, Union Oil tested steam production in the Gunung Salak
geothermal field, located near Jakarta.  Union Oil will supply steam to two
generating  plants with a combined 110-megawatt capacity under  a  contract
with PERTAMINA, the Indonesian state oil company.  The plants are scheduled
to  begin operation in the second quarter of 1994.  The contract also calls
for  Union  Oil to develop steam to supply an additional 220  megawatts  of
generating  capacity at Salak as development proceeds.  Union  Oil  is  now
negotiating to expand its role and accelerate development.
   
   On  northern Sumatra, Union Oil will begin exploration drilling  in  the
Sarulla block in mid-1994. The company signed a contract with PERTAMINA  in
February  1993 to appraise and develop geothermal resources of up to  1,000
megawatts  in the 240,000-acre tract south of Medan.  If this  resource  is
proven, Union Oil will build and operate the power plants at Sarulla  under
an  energy sales contract with PLN, the Indonesian State Electric  Company.
The  contract  calls for the transfer of the power plants to PLN  after  an
agreed  period  of  operation.  Following the  transfer,  Union  Oil  would
continue to sell geothermal energy to PLN for the remaining project life.

   Below are geothermal reserves and operating data:

OTHER OPERATIONS

REAL ESTATE

   The  Real  Estate Division is responsible for managing and disposing  of
surplus  company-owned properties.  The Division manages office  facilities
and  also  handles  the office leasing and sub-leasing operations  for  the
company.  Unocal Land & Development Company, a wholly owned subsidiary,  is
responsible for the development and sale of certain real estate assets  for
industrial, commercial and residential purposes.

RESEARCH

   Union  Oil  has approximately 560 company research scientists, engineers
and  support  personnel  working  at a research  center  located  in  Brea,
California.    Their  primary  functions  are  to  provide  the   operating
divisions with technical services which improve the overall performance  of
their  operations and to develop new and improved products,  processes  and
techniques  for  use  in  every  phase of the  petroleum  business  and  in
pertinent  areas of the chemical and geothermal industries.  A majority  of
the research group reports to the operating divisions.
   
   Union  Oil  owns  over  1,223 active patents in the  United  States  and
abroad  which  are  generally available to others under  revenue  producing
licensing agreements.  In 1993, Union Oil sold 19 such licenses.
   
   The  company's  total  research and development  expenditures  were  $29
million in 1993, $50 million in 1992 and $63 million in 1991.  Expenditures
for  technical services were $57 million, $44 million and $41  million  for
the years 1993, 1992 and 1991, respectively.

COMPETITION

   The  petroleum industry is highly competitive.  Union Oil competes  with
numerous companies in all phases of its petroleum operations.  The  company
is  also in competition with other producers and marketers of non-petroleum
energy.
   
   Competition for finding, developing and producing oil and gas  resources
occurs  in  bidding for domestic prospective leases or foreign  exploration
rights,  acquisition of geological, geophysical and engineering  knowledge,
and  the  cost-efficient development and production of proved oil  and  gas
reserves.   The  future  availability of  prospective  domestic  leases  is
subject  to  competing land uses and federal, state and local statutes  and
policies.   The  company's geothermal operations are  in  competition  with
producers of other energy resources.
   
   Competition  also exists in the manufacture, distribution and  marketing
of  petroleum  products.  In the refining segment, the ability  to  produce
high-value  products  at  a  competitive  cost,  while  meeting  regulatory
standards,  is  of  primary  importance.  On  the  marketing  side,  price,
customer  service, advertising and new product development  are  the  major
factors  affecting  competition.   In  the  chemical  businesses,  the  key
competitive factors for the company's fertilizer products are prices,  cost
and  availability of gas supplies; and for petroleum coke, product  quality
and prices.

EMPLOYEES

   As  of  December 31, 1993, Union Oil had 13,607 employees compared  with
14,674  a  year  ago.   The  decrease principally reflects  the  impact  of
business  divestments.  Of the total employees, 2,248 were  represented  by
various  labor unions.  Salaries, wages and employee benefits totaled  $744
million in 1993, $816 million in 1992 and $842 million in 1991.
   
   Collective  bargaining  agreements  covering  represented  employees  at
Union  Oil's  refineries  and various other facilities  were  entered  into
during February of 1993.  Most of these new labor agreements are for three-
year terms.

<PAGE>

GOVERNMENT REGULATION

   Certain  interstate crude oil pipeline subsidiaries  of  Union  Oil  are
regulated (as common carriers) by the Federal Energy Regulatory Commission.
As  lessee  from  the United States government, Union  Oil  is  subject  to
Department  of the Interior regulations covering activities  on  the  Outer
Continental  Shelf  (OCS),  and  on  onshore  lands.   In  addition,  state
regulations  impose strict controls on both state-owned and privately-owned
lands.
   
   Some  federal  and  state  bills would, if  enacted,  significantly  and
adversely  affect Union Oil and the petroleum industry.  These include  the
imposition of additional taxes, divestiture of certain operations, land use
controls and restrictions on development of the OCS.
   
   Regulations  promulgated by the Environmental Protection  Agency  (EPA),
the  Department  of  the  Interior, the Department  of  Energy,  the  State
Department,  the Department of Commerce and other government  agencies  are
complex  and  subject  to change.  New regulations  may  be  adopted.   The
company  cannot  predict how existing regulations  may  be  interpreted  by
enforcement agencies or court rulings, nor whether amendments or additional
regulations will be adopted, nor what effect such changes may have  on  its
business or financial condition.
   
ENVIRONMENTAL REGULATION

   Federal,  state and local laws and provisions regulating  the  discharge
of  materials  into the environment or otherwise relating to  environmental
protection   have   a  continuing  impact  on  the  company's   operations.
Significant  federal  legislation applicable to  the  company's  operations
includes the following:  the Clean Water Act, as amended in 1977; the Clean
Air  Act,  as  amended in 1977 and 1990; the Solid Waste Disposal  Act,  as
amended  by the Resource Conservation and Recovery Act of 1976, as  amended
in   1984;  the  Comprehensive  Environmental  Response,  Compensation  and
Liability  Act  of 1980, as amended in 1986 (CERCLA); the Toxic  Substances
Control Act of 1976, as amended in 1986; and the Oil Pollution Act of 1990.
Various  state  and local governments have adopted or are  considering  the
adoption of similar laws and regulations.
   
   The  California Air Resources Board and the federal government have both
adopted  new standards for gasoline.  The Federal Clean Air Act  Amendments
of 1990 require the manufacture and sale of reformulated gasolines in areas
not  meeting  specified air quality standards by January  1,  1995.   These
requirements apply to the nine areas which have the worst ozone  pollution,
including  Los  Angeles and San Diego.  The California Air Resources  Board
has established stricter standards than those imposed by the federal rules.
These standards for reformulated gasoline are to become effective March  1,
1996.   The  company  expects to spend $450 million over  the  three  years
ending  in  early  1996 to modify its refineries to meet  these  regulatory
standards.
   
   The  Air  Quality Management Plan for the Los Angeles Basin, as adopted,
and the Clean Air Act Amendments could, by the year 2000, significantly and
adversely  affect  all  of the company's petroleum operations  in  the  Los
Angeles  area,  including  its refining operations  located  near  the  Los
Angeles harbor and in Carson.  The company believes it can continue to meet
the  requirements  of  existing laws and regulations, although  changes  in
operating  procedures and the acquisition of additional  pollution  control
facilities may be necessary to meet future regulatory standards.
   
   The  company has been a party to a number of administrative and judicial
proceedings   under  federal,  state  and  local  provisions  relating   to
environmental  protection.   These proceedings include  actions  for  civil
penalties or fines for alleged environmental violations, permit proceedings
including  hearing requests into the issuance or modification  of  National
Pollution  Discharge  Elimination  System  (NPDES)  permits,  requests  for
temporary  variance from air pollution regulations for refinery operations,
and  similar matters.  The company has also joined or intervened  with  the
American Petroleum Institute, the Western States Petroleum Association  and
with other oil companies in actions relating to guidelines and proposed and
final  regulations  of the EPA, the Department of the  Interior  and  other
agencies.
   
   In  1993,  the  company  spent approximately  $133  million  in  capital
expenditures  in  order  to  comply with and, in  some  cases,  exceed  the
requirements  of  applicable  federal and state environmental  regulations.


                                    14
<PAGE>

The company  also  incurred  approximately $235 million of  environment-related
expense.   This  includes expenditures to remediate past contamination  and
Union  Oil's  operating, maintenance, and administrative costs to  maintain
environmental  compliance.  Estimated 1994 environmental  expenditures  are
$296 million in capital and $242 million in expense.
   
   For  information  on  the company's environmental  exposure,  see  Legal
Proceedings  below  and the Environmental Matters section  of  Management's
Discussion and Analysis on page 22 and Note 16 of the notes to consolidated
financial statements on page 43 of this report.

OTHER MATTERS

   In  the  first  quarter  of 1994, the company plans to  write  down  its
remaining  investment  of $24.6 million in the Guadalupe  Oil  Field.    On
March  4, 1994, Union Oil announced that if negotiations with the landowner
permit  the company to do so, it will permanently cease production  at  the
field which currently produces 170 barrels of low gravity oil per day.  The
net cost to abandon the field is approximately $8 million.
   
   On  March  15, 1994, the company pleaded no contest to three misdemeanor
counts  and  paid  penalties  of $1.5 million.  The  remaining  misdemeanor
counts  against the company and six employees were dropped by the San  Luis
Obispo  County  District Attorney.  On March 23, 1994,  a  lawsuit  seeking
civil  penalties was filed by the California Attorney General.   See  Legal
Proceedings on page 16, Item 4, for additional information.
   
   The  company will continue to concentrate on the cleanup of the  diesel-
like  additive formerly used to help produce the heavy crude oil.  To  date
the  company  has  spent about $1.5 million in cleanup  costs.   Additional
immediate  remedial cleanup is estimated at another $2 million.   A  longer
term  remediation plan is being formulated.  Although the cleanup cost  has
not  been  determined it is not expected to have a material effect  on  the
company's operating results or financial condition.

                 UNION OIL COMPANY OF CALIFORNIA


                    a California Corporation



George C. Bond and R. O. Hedley certify that:


  1.  They are a duly elected and acting Vice President and the
duly elected and acting Secretary respectively, of said
corporation.

  2.  The Articles of Incorporation of said corporation shall be
amended and restated to read in full as follows:

     One:  The name of the corporation is: UNION OIL COMPANY OF
CALIFORNIA.

     Two:  The purpose of the corporation is to engage in any
lawful act or activity for which a corporation may be organized
under the General Corporation Law of California other than the
banking business, the trust company business, or the practice of a
profession permitted to be incorporated by the California
Corporations Code.

     Three:  The corporation shall have the power to offer, issue
and to sell pro rata to the holders of its Common Shares, shares of
its capital stock other than shares of stock issued and sold under
and pursuant to the provisions of (1) and (2) of the second
paragraph of this Article Three, and to sell to others any shares
of stock so offered to the holders of the Common Shares and not
taken by them for such price or consideration as the Board of
Directors may determine.

     Notwithstanding the foregoing provisions of this Article
Three, (1) the Corporation may issue shares of its capital stock,
and of any future increase thereof, in such amounts as may be
determined by the affirmative vote of two-thirds of the entire
Board of Directors, in exchange for or in payment for property to 
be acquired by the Corporation for carrying out any of the 
foregoing purposes, without first offering such stock to its 


<PAGE>


stockholders; also, upon affirmative vote of two-thirds of the 
entire Board of Directors of this Corporation, and without any
prior offering to stockholders of this Corporation, the Corporation
may grant to the purchasers or the holders of any bonds or
debentures or evidences of indebtedness of this Corporation,
optional rights to convert any of such securities, in whole or in
part, into shares of the capital stock of this Corporation, and of
any future increase thereof, and also of any subsequent offering
thereof, or the optional rights to purchase any of such shares, all
on such terms and conditions and at such price or prices, and in
such manner, at such times and in such amounts as may be determined
by such vote of directors, and on any such optional rights being
exercised by the holder thereof, may issue the capital stock called
for by the exercise of such rights; and (2) the Corporation may
offer, issue and sell, and grant options to purchase Common Shares
to such employees of the Corporation and its subsidiaries, in such
amounts, upon such terms and conditions and for such consideration
as the Board of Directors may from time to time determine, but not
to exceed in the aggregate 500,000 Common Shares; provided however,
that such maximum amount shall be subject to adjustment (in the
same manner as the Corporation's outstanding Common Shares) in the
event a dividend is declared upon the Common Shares of the
Corporation payable in Common Shares or in the event the
outstanding Common Shares of the Corporation shall be changed into
or exchanged for a different number or class of shares of stock or
other securities of the Corporation or of another corporation,
whether through reorganization, recapitalization, stock split-up,
combination of shares, merger or consolidation, and that the
provisions of this section shall be applicable to the number or
class of shares of stock or other securities, which in accordance
herewith, may be substituted for such 500,000 Common Shares; and
provided further that in the case of any sale of such shares the
price shall not be less than the fair market value thereof at the
time of sale as determined by the Board of Directors, and that in
the case of any option to purchase such shares, the price shall not
be less than the fair market value thereof at the time of granting
such option, as so determined. For the purposes and within the
aggregate limit above mentioned, such Common Shares (subject to
adjustment as above provided) may be issued without any prior
offering to stockholders of this Corporation.   

     Four:  The number of directors of this Corporation shall be
not less than twelve nor more than fifteen. The exact number of
directors shall be fixed, within the limits specified herein, by a
by-law or amendment thereof duly adopted by the shareholders or by
the Board of Directors of this Corporation.

     Five:  The Corporation is authorized to issue one class of
shares of capital stock to be designated Common Shares. The 
aggregate par value of all shares that are to have a par value is
$541,666,666.66-2/3. The number of shares that are to have a par 

                               -2-

<PAGE>

value is 65,000,000, all of which shall be Common Shares, and the
par value of each of such shares is $8-1/3.
                                
     Six:  The Corporation elects to be governed by all of the
provisions of the General Corporation Law of California (as enacted
by Chapter 682 of the 1975 California Statutes and as subsequently
amended) not otherwise applicable to it under Chapter 23 thereof.

3.  The foregoing amendment and restatement has been approved by
the Board of Directors of said Corporation.

4.  The foregoing amendments may be adopted with approval of the
Board of Directors alone, because such amendments (i) conform the
statement of purposes and powers to subdivision (b) of Section 202
of the General Corporation Law and may be adopted pursuant to
Section 2302 of the General Corporation Law; (ii) delete references
to the location of the principal office and may be adopted pursuant
to Section 2302 of the General Corporation Law; (iii) delete the
names and addresses of the persons appointed to act as initial
directors and omit the name and address of the initial agent and
may be adopted pursuant to Section 902(d) of the General
Corporation Law; and (iv) delete references to the Preferred Shares
which were redeemed by the Corporation, and may be adopted pursuant
to Section 510(b) of the General Corporation Law. All 10,275,397
Preferred Shares authorized to be issued were issued in exchange
for shares of the Pure Oil Company when said corporation was merged
into Union Oil Company of California. All of said authorized
Preferred Shares were converted or redeemed by the Corporation.

     IN WITNESS WHEREOF, the undersigned have executed this
Certificate on April 24, 1978.

entitled to vote with respect to the foregoing amendment was
