                                PROXY STATEMENT

                                                                  March 8, 2000

  This proxy statement is furnished in connection with the solicitation by the
Board of Directors of Schlumberger Limited (Schlumberger N.V.) ("the Company")
of proxies to be voted at the 2000 Annual General Meeting of Stockholders. The
approximate mailing date of this proxy statement is March 8, 2000. Business at
the meeting is conducted in accordance with the procedures determined by the
Chairman of the meeting and is generally limited to matters properly brought
before the meeting by or at the direction of the Board of Directors or by a
stockholder in accordance with specified requirements requiring advance notice
and disclosure of relevant information.

  The Schlumberger 1999 Annual Report to Stockholders has been mailed under
separate cover. The Company's Consolidated Balance Sheet as at December 31,
1999, its Consolidated Statement of Income for the year ended December 31,
1999 and the supplemental financial information with respect to dividends
included in the Annual Report are incorporated by reference as part of this
proxy soliciting material.

  The Company will bear the cost of furnishing proxy material to all
stockholders and of soliciting proxies by mail and telephone. D. F. King &
Co., Inc. has been retained by the Company to assist in the solicitation of
proxies for a fee estimated at $10,000 plus reasonable expenses. The Company
will reimburse brokerage firms, fiduciaries and custodians for their
reasonable expenses in forwarding the solicitation material to the beneficial
owners.

Voting Procedure

  Each stockholder of record at the close of business on February 24, 2000 is
entitled to one vote for each share registered in the stockholder's name. On
that date there were          outstanding shares of common stock of
Schlumberger, excluding            shares held in treasury.

  Fifty percent of the outstanding shares, exclusive of shares held in
treasury, must be present in person or by proxy to constitute a quorum for the
holding of the meeting. Abstentions and broker non-votes are counted for
determining the presence of a quorum but are not counted as votes cast in the
tabulation of votes on any matter brought before the meeting.

  Shares cannot be voted at the meeting unless the owner of record is present
in person or is represented by proxy. Schlumberger is incorporated in the
Netherlands Antilles and, as required by the Schlumberger Deed of
Incorporation, meetings of stockholders must be held in Curacao. The enclosed
proxy card is a means by which a stockholder may authorize the voting of
shares at the meeting. It may be revoked at any time by written notice to the
Secretary of the Company before it is voted. If it is not revoked, the shares
represented will be voted in accordance with the proxy.

                           1. Election of Directors

  It is intended to fix the number of directors at 12 and to elect a Board of
Directors of 12 members, each to hold office until the next Annual General
Meeting of Stockholders and until a director's successor is elected and
qualified or until a director's death, resignation or removal. Each of the
nominees is now a director and was previously elected by the stockholders.

12 nominees named below. If any nominee is unable or unwilling to serve,
proxies may be voted for another person designated by the Board of Directors.

serve if elected.

director.

Stock Option Grants Table

The following table sets forth certain information concerning options granted
during 1999 to the Chief Executive Officer and the next four most highly
compensated executive officers. Shown are hypothetical gains that could be
realized for the respective options, based on assumed rates of annual compound
stock price appreciation of 5% and 10% from the date the options were granted
over the ten-year term of the options. Any amount realized upon exercise of
the options will depend upon the market price of Schlumberger common stock at
the time the option is exercised relative to the exercise price of the option.
There is no assurance that the amounts reflected in this table will be
realized.

Pension Plans

  Schlumberger and certain of its subsidiaries maintain pension plans for
employees, including executive officers, providing for lifetime pensions upon
retirement after a specified number of years of service. Employees may
participate in one or more pension plans in the course of their careers with
the Company or its subsidiaries, in which case they become entitled to a
pension from each plan based upon the benefits accrued during the years of
service related to each plan. These plans are funded on an actuarial basis
through cash contributions made by the Company or its subsidiaries. Certain of
the plans also permit or require contributions by employees.

  Benefits under the international staff pension plans of the Company and
certain of its subsidiaries are based on a participant's pensionable salary
(generally, base salary plus incentive) for each year in which the employee
participates in the plans and the employee's length of service with the
Company or the subsidiary. Since January 1, 1993, the benefit earned has been
3.2% of pensionable salary for each year of service. Benefits are payable upon
normal retirement age, at or after age 55, or upon early retirement. Estimated
annual benefits from these plans payable upon retirement are: $33,714 for Mr.
Baird; $57,139 for Mr. Grijalva; $276,635 for Mr. Gould, assuming pensionable
salary continues at the December 31, 1999 level for Mr. Gould, and $47,875 for
Mr. Liu.

  Benefits under the U.S. tax qualified pension plans of the Company and
certain of its subsidiaries are based on an employee's admissible compensation
(generally, base salary plus incentive) for each year in which an employee
participates in the U.S. plans and the employee's length of service with the
Company or the subsidiary. From January 1, 1989, the benefit earned has been
1.5% of admissible compensation for service prior to the employee's completion
of 15 years of active service and 2% of admissible compensation for service
after completion of 15 years of active service. The Company has adopted a
supplementary benefit plan for eligible employees, including executive
officers. Amounts under the supplementary plan are accrued under an unfunded
arrangement to pay each individual the additional amount which would have been
payable under the plans if the amount had not been subject to limitations
imposed by law on maximum annual benefit payments and on annual compensation
recognized to compute plan benefits. Estimated annual benefits from the plans
payable upon retirement are: $16,066 for Mr. Gould, and, assuming admissible
compensation continues at the December 31, 1999 levels, estimated annual
benefits payable from the U.S. plans and the supplementary benefit plan are:
$633,069 for Mr. Baird; $291,336 for Mr. Grijalva; $236,521 for Mr. Pfister,
and $159,529 for Mr. Liu.

                          Corporate Performance Graph

  The following graph compares the yearly percentage change in the cumulative
total stockholder return on Schlumberger common stock, assuming reinvestment
of dividends on the last day of the month of payment into common stock of
Schlumberger, with the cumulative total return on the published Standard &
Poor's 500 Stock Index and the cumulative total return on Value Line's
Oilfield Services Industry Group over the preceding five-year period. The
following graph is presented pursuant to Securities and Exchange Commission
rules. Schlumberger believes that while total stockholder return is an
important corporate performance indicator, it is subject to the vagaries of
the market. In addition to the creation of stockholder value, the Schlumberger
executive compensation program is based on financial and strategic results and
the other factors set forth and discussed in the Compensation Committee Report
beginning on page 12.

Compensation Committee Report on Executive Compensation

  The Compensation Committee of the Board of Directors is comprised entirely
of outside directors who review and approve compensation programs applicable
to executive officers. Specific awards for these officers are approved by the
committee.

  Three programs continue to provide the core compensation vehicles for
executive officers:

  --Base Salaries
  --Annual Cash Incentive Awards
  --Stock Option Grants

  For many years, Schlumberger has emphasized career opportunities by
recruiting from colleges and universities in countries where Schlumberger
works (more than 70 countries throughout the world), supporting mobility and
maintaining competitive compensation programs which are based on an employee's
contribution and potential rather than country of origin.

  Thus, the three programs noted above are applicable not only to executive
officers, but to thousands of managerial, professional and technical employees
of Schlumberger. At all levels, employees enjoy competitive base salaries.
Participation in an annual cash incentive program is added to the compensation
package as employees advance, with the size of incentive opportunity
increasing as one progresses in the organization.

  Within the first few years of employment, those with strong performance as
well as outstanding potential may be awarded stock option grants, which are
discretionary in nature.

  In this way, an increasing portion of the successful employee's total
compensation becomes leveraged against yearly results and Company long-term
appreciation due to the expanding role played by cash incentives and stock
options in the total compensation package.

  The Company's subsidiaries also have profit sharing plans that provide
annual deferred awards based on the results of the fiscal year for the
subsidiary sponsoring the plan. These awards also tend to increase the portion
of total compensation which is leveraged against business results.

  Base salaries are reviewed annually for competitiveness against a database
of comparator company information provided by outside compensation
consultants. The companies in the database reflect those broad industry
segments in which Schlumberger competes -- oil-related, high technology and
high volume manufacturing. The companies in the database may change slightly
from year to year due to mergers and acquisitions as well as the normal
movement of companies into and out of the database at their own volition. The
same companies used for executive officer base salary ranges are used for
professional and managerial employees of Schlumberger throughout the world.

                                      12
<PAGE>

  The comparator companies used for compensation purposes are different from
those in the Corporate Performance Graph (the Value Line Oilfield Services
Industry Group). The Value Line companies do not constitute a source of
recruits nor do they reflect all the industry segments in which Schlumberger
operates.

  While executive officer base salary levels are studied annually, they are
adjusted less frequently. Except for significant changes in responsibility, an
executive officer's base salary may be increased only every three to five
years and then by a significant amount. This has allowed the Company to focus
primarily on variable compensation during periods of low inflation.

  Consistent with this policy, Andrew Gould's salary was increased on his
promotion to Executive Vice President with responsibility for the entire
Oilfield Services group. One named executive officer was appointed in 1999,
Jack Liu, to succeed Arthur Lindenauer as Executive Vice President, Finance.

  Annual cash incentive awards for each executive officer are payable early in
the calendar (fiscal) year and reflect performance against targets or
objectives established early in the preceding year.

  For all executive officers, incentive awards are calculated as a percent of
the base salary paid for the completed calendar year. The percent varies among
executive officer positions to reflect the differing levels of potential
impact on Company results. For 1999, the incentive award ranges were:

  --0 to 100% for Mr. Baird

  --0 to 75% for Messrs. Grijalva, Gould and Pfister

  --0 to 60% for Mr. Liu

  With exceptional results, the incentive ranges can be exceeded.

  One-half of the incentive potential for each executive officer is a function
of performance against financial targets for the Company or the business
sector for which the executive officer is responsible. In 1999, the Company
objectives were divided between specific numerical targets and earnings; the
business sector target is net income for that sector.

  The second half of the incentive potential is a reflection of performance
against various objectives of each executive officer. Objectives may be
strategic or personal and may relate solely to the completed fiscal year or be
interim measures against longer-term objectives. Achievement against
objectives is determined subjectively.

  The continued downturn in the oil business in 1999 affected the financial
results and the incentive awards of three named executive officers (Messrs.
Grijalva, Gould and Liu). Their total cash compensation for 1999 is at or
below the median of available comparator market data. Mr. Pfister's incentive
is based on financial results of Automated Test Equipment, Smart Cards and
Terminals, and the sale of Retail Petroleum Systems, the results of which were
finalized in 1999. Based on results, Mr. Pfister's total cash compensation is
at the median of comparator market data.

                                      13
<PAGE>

  Stock option grants were awarded in 1999 on a general basis throughout
Schlumberger to professional, managerial and technical employees deemed
eligible for consideration. Such reviews are conducted every 18 months to two
years. Grants are awarded on an entirely discretionary basis to individuals
demonstrating exceptional performance in their current positions as well as
the likelihood of continuing high quality performance in the future. In
addition, grants typically are awarded between general reviews to recognize
promotions, substantial changes in responsibility, and significant individual
or team achievements. The 1999 grants emphasized high potential employees
early in their careers with Schlumberger.

  Of the named executive officers, Messrs. Gould, Pfister and Liu were awarded
stock option grants in 1999.

  The stock option grants awarded by the Company are uniform in their terms
for executive officers as well as all other optionees -- 10-year term, vesting
in 20% steps at the first through fifth anniversary of grant date, and option
price equal to fair market value on date of grant.

  The Company does not utilize below-market options, stock appreciation
rights, phantom stock, restricted stock, performance units or reload options.
Section 162(m) of the Internal Revenue Code limits the deductibility of
certain compensation expenses in excess of $1,000,000 per individual. The
committee does not believe that the cash compensation payable in excess of
this amount for fiscal year 1999 will result in any material loss of tax
deduction. Therefore, the committee has elected not to follow the provisions
of Section 162(m) with regard to cash compensation. The Company's stock option
plans are believed to be in compliance with the provisions of Section 162(m).

Bases for the Compensation of the Chief Executive Officer

  The same database of companies used for comparison purposes to review base
salaries of other executive officers (and managerial employees throughout the
Schlumberger universe) is studied to consider the base salary of the Chief
Executive Officer. The database reflects the industry segments in which the
Company operates -- oil-related, high technology and high volume
manufacturing.

  The Chief Executive Officer's salary remained at $1,500,000 during 1999.

  The potential cash incentive award for Mr. Baird for 1999 was 100% of base
salary. As with other executive officers with corporate responsibility, one-
half of this award potential was a measure of performance against specific
financial targets for the Company. These financial targets were not fully
achieved in 1999 so payment on this half of the incentive award is in
proportion to the results.

  The second half of the award potential reflects the committee's evaluation
of Mr. Baird's performance against strategic objectives established early in
1999 for the calendar year. These objectives were a combination of market
growth, acquisition, and organizational changes. Disclosure of specific
measures applied to evaluate achievement of Mr. Baird's objectives could
adversely affect the Company's competitive position.

  The total cash incentive awarded Mr. Baird for 1999 performance was
$1,000,000. In combination with base salary, this places him at the median of
available comparator market data.

  Mr. Baird has no employment agreement with the Company.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Summary of Accounting Policies
The Consolidated Financial Statements of Schlumberger Limited and its
subsidiaries have been prepared in accordance with accounting principles
generally accepted in the United States.

DISCONTINUED OPERATIONS
On December 31, 1999, Schlumberger completed the spin-off of its offshore
contract drilling business, Sedco Forex, to its stockholders and the subsequent
merger of Sedco Forex and Transocean Offshore Inc., which changed its name to
Transocean Sedco Forex Inc. following the merger. The results for the Sedco
Forex operations spun off by Schlumberger are reported as Discontinued
Operations for all periods presented in the Consolidated Statement of Income.

PRINCIPLES OF CONSOLIDATION
The Consolidated Financial Statements include the accounts of majority-owned
subsidiaries. Significant 20% - 50% owned companies are carried on the equity
method and classified in Investments in Affiliated Companies. The pro rata share
of Schlumberger after-tax earnings is included in Interest and other income.
Equity in undistributed earnings of all 50%-owned companies on December 31, 1999
was not material.

USE OF ESTIMATES
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities, disclosure of contingent
assets and liabilities at the date of the financial statements and the reported
amounts of revenue and expenses during the reporting period. While actual
results could differ from these estimates, management believes that the
estimates are reasonable.

REVENUE RECOGNITION
Generally, revenue is recognized after services are rendered or products are
shipped.

TRANSLATION OF NON-US CURRENCIES
Oilfield Services' functional currency is primarily the US dollar. Resource
Management Services' and Test & Transactions' functional currencies are
primarily local currencies. All assets and liabilities recorded in functional
currencies other than US dollars are translated at current exchange rates. The
resulting adjustments are charged or credited directly to the Stockholders'
Equity section of the Consolidated Balance Sheet. Revenue and expenses are
translated at the weighted-average exchange rates for the period. All realized
and unrealized transaction gains and losses are included in income in the period
in which they occur. Schlumberger policy is to hedge against unrealized gains
and losses on a monthly basis. Included in the 1999 results were transaction
losses of $12 million, compared with losses of $6 million and $10 million in
1998 and 1997, respectively.

Currency exchange contracts are entered into as a hedge against the effect of
future settlement of assets and liabilities denominated in other than the
functional currency of the individual businesses. Gains or losses on the
contracts are recognized when the currency exchange rates fluctuate, and the
resulting charge or credit partially offsets the unrealized currency gains or
losses on those assets and liabilities. On December 31, 1999, contracts and
options were outstanding for the US dollar equivalent of $110 million in various
foreign currencies. These contracts mature on various dates in 2000 and 2001.

Investments
Both short-term and long-term investments held to maturity are stated at cost
plus accrued interest, which approximates market, and comprise primarily
eurodollar time deposits, certificates of deposit and commercial paper,
euronotes and eurobonds, substantially all denominated in US dollars.
Substantially all the investments designated as held to maturity that were
purchased and sold during the year had original maturities of less than three
months. Short-term investments that are designated as trading are stated at
market. The unrealized gains/losses on such securities on December 31, 1999 were
not significant.

For purposes of the Consolidated Statement of Cash Flows, Schlumberger does not
consider short-term investments to be cash equivalents as they generally have
original maturities in excess of three months.

                                       5
<PAGE>

Short-term investments at December 31, 1999 and 1998, were $4.26 billion and
$3.85 billion, respectively.

Inventories
Inventories are stated principally at average cost or at market, if lower.
Inventory consists of materials, supplies, finished goods and nonexclusive
proprietary seismic surveys.

Excess of Investment Over Net Assets of Companies Purchased
Cost in excess of net assets of purchased companies (goodwill) is amortized on a
straight-line basis over 5 to 40 years. Accumulated amortization was $516
million and $434 million on December 31, 1999 and 1998, respectively. Of the
goodwill on December 31, 1999, 40% is being amortized over 40 years, 11% is
being amortized over 28 years, 23% is being amortized over 25 years and 26% is
being amortized over periods of up to 25 years.

Fixed Assets and Depreciation
Fixed assets are stated at cost less accumulated depreciation, which is provided
for by charges to income over the estimated useful lives of the assets using the
straight-line method. Fixed assets include the manufacturing cost (average cost)
of oilfield technical equipment manufactured by subsidiaries of Schlumberger.
Expenditures for renewals, replacements and improvements are capitalized.
Maintenance and repairs are charged to operating expenses as incurred. Upon sale
or other disposition, the applicable amounts of asset cost and accumulated
depreciation are removed from the accounts and the net amount, less proceeds
from disposal, is charged or credited to income.

Capitalized Interest
Schlumberger capitalizes interest expense during the new construction or upgrade
of qualifying assets. Interest expense capitalized in 1999 and 1998 was $5
million and $7 million, respectively. No interest expense was capitalized in
1997.

Impairment of Long-lived Assets
Schlumberger reviews the carrying value of its long-lived assets, including
goodwill, whenever events or changes in circumstances indicate that the
historical cost-carrying value of an asset may no longer be appropriate.
Schlumberger assesses recoverability of the carrying value of the asset by
estimating the future net cash flows expected to result from the asset,
including eventual disposition. If the future net cash flows are less than the
carrying value of the asset, an impairment loss is recorded equal to the
difference between the asset's carrying value and fair value.

Taxes on Income
Schlumberger and its subsidiaries compute taxes on income in accordance with the
tax rules and regulations of the many taxing authorities where the income is
earned. The income tax rates imposed by these taxing authorities vary
substantially. Taxable income may differ from pretax income for financial
accounting purposes. To the extent that differences are due to revenue or
expense items reported in one period for tax purposes and in another period for
financial accounting purposes, an appropriate provision for deferred income
taxes is made.

Approximately $3.2 billion of consolidated income retained for use in the
business on December 31, 1999 represented undistributed earnings of consolidated
subsidiaries and the pro rata Schlumberger share of 20%-50% owned companies. No
provision is made for deferred income taxes on those earnings considered to be
indefinitely reinvested or earnings that would not be taxed when remitted.

Tax credits and other allowances are credited to current income tax expense
using the flow-through method of accounting.

Earnings Per Share
Basic earnings per share is calculated by dividing net income by the average
number of common shares outstanding during the year. Diluted earnings per share
is calculated by dividing net income by the average number of common shares
outstanding assuming dilution, the calculation of which assumes that all stock
options and warrants which are in the money are exercised at the beginning of
the period and the proceeds used, by Schlumberger, to purchase shares at the
average market price for the period. The following is a reconciliation from
basic earnings per share to diluted earnings per share from continuing
operations for each of the last three years:

1999 and 1998 Charges--CONTINUING OPERATIONS
Schlumberger recorded the following charges in continuing operations in 1999 and
1998:

In December 1999, a pre-tax charge of $77 million ($71 million after tax, $0.13
per share - diluted), classified in Cost of goods sold and services, consisting
primarily of the following:

o    A charge of $31 million ($26 million after tax) including $23 million of
     asset impairments and $8 million of severance costs related to reductions
     in the marine seismic fleet due to depressed market conditions.
o    A charge of $38 million ($37 million after tax) including $33 million of
     asset impairments and $5 million of severance costs related to the
     restructuring of its land drilling activity following the spin-off of its
     offshore drilling business to stockholders.

In March 1999, a pretax charge of $147 million partially offset by a pretax gain
of $103 million (net - $58 million after tax, $0.10 per share - diluted),
consisting of the following:

o    A charge of $118 million ($118 million after tax) related to the downsizing
     of its global Oilfield Services activities, including $108 million of
     severance costs and $10 million for asset impairments.
o    A charge of $29 million ($20 million after tax) related to RMS and Test &
     Transactions, consisting

                                       7
<PAGE>

     principally of $16 million of severance costs at several RMS facilities
     resulting from a downturn in business and $5 million of asset write-downs.

o    A credit of $103 million ($80 million after tax) from the gain on the sale
     of financial instruments received in connection with the 1998 sale of RPS.

The pretax gain on the sale of financial instruments is included in Interest &
other income. The pretax charge of $147 million is classified in Cost of goods
sold and services.

In September 1998, a pretax charge of $432 million ($368 million after tax,
$0.65 per share - diluted), classified in Cost of goods sold and services,
consisting primarily of the following:

o    A charge of $314 million ($257 million after tax) related to Oilfield
     Services, including severance costs of $69 million; facility closure costs
     of $61 million; operating assets write-offs of $137 million; and $43
     million of customer receivable reserves where collection was considered
     doubtful due to the customers' financial condition and/or country risk.
     This charge was due to the reduction in business activity.
o    A charge of $48 million ($63 million after tax) for merger-related costs
     in connection with the acquisition of Camco.
o    A charge of $61 million ($43 million after tax) related to RMS and Test &
     Transactions, consisting primarily of $21 million of severance and $40
     million of environmental costs resulting from a reassessment of ongoing
     future monitoring and maintenance requirements at locations no longer in
     operation.

Severance costs included in the September 1998 charge (6200 people; $90 million)
and the March 1999 charge (4700 people; $124 million) have been paid. The actual
number of employees terminated was slightly higher than originally planned;
however, this had no material impact on the actual severance costs paid as
compared with the amount originally accrued. The December 1999 charge included
severance costs of $13 million (300 people) of which $5 million had been paid at
December 31, 1999.

The $61 million of facility closure costs accrued in 1998 have substantially
been paid in accordance with the original plan.

Discontinued Operations

On December 31, 1999, Schlumberger completed the spin-off of its offshore
contract drilling business, Sedco Forex, to its stockholders and the subsequent
merger of Sedco Forex and Transocean Offshore Inc., which changed its name to
Transocean Sedco Forex Inc. following the merger. The spin-off was approved by
stockholders on December 10, 1999.

Upon completion of the merger, Schlumberger stockholders held approximately 52%
of the ordinary shares of Transocean Sedco Forex Inc., and Transocean Offshore
Inc. shareholders held the remaining 48%. Schlumberger retained no ownership in
the combined company.

In the spin-off, Schlumberger stockholders received one share of Sedco Forex for
each share of Schlumberger owned on the record date of December 20, 1999. In the
merger, each Sedco Forex share was exchanged for 0.1936 ordinary share of
Transocean Sedco Forex Inc. Stockholders received cash in lieu of fractional
shares.

Results for the Sedco Forex operations spun off by Schlumberger for this
transaction are reported as discontinued operations for all periods presented in
the Consolidated Statement of Income.

Discontinued Operations on the Consolidated Statement of Income includes the
operating results of the spun-off Sedco Forex business and the following
charges:

o    In December 1999, an after-tax charge of $50 million ($0.09 per share -
     diluted) for costs directly associated with the spin-off.
o    In March 1999, an after-tax charge of $33 million ($0.06 per share -
     diluted) for severance costs ($13 million) and legal claims.
o    In September 1998, an after-tax charge of $12 million ($0.02 per share -
     diluted) for severance costs.

                                       8
<PAGE>

As a result of the spin-off, Schlumberger Income Retained for Use in the
Business was reduced by $918 million representing the spun-off net assets of
Sedco Forex ($1.23 billion) less payments received in settlement of intercompany
balances between Schlumberger and Sedco Forex ($313 million). The net assets
spun off included $1.3 billion of fixed assets.

Pursuant to Accounting Principles Board Opinion (APB) No. 30, Reporting the
Results of Operations-Reporting the Effects of Disposal of a Segment of a
Business, and Extraordinary, Unusual and Infrequently Occurring Events and
Transactions, the revenue and expenses of Sedco Forex have been excluded from
the respective captions in the Consolidated Statement of Income. The net
operating results of Sedco Forex have been reported, net of applicable income
taxes, as Discontinued Operations.

Summarized financial information for the discontinued operations, is as follows:

Acquisitions

During 1999, subsidiaries of Schlumberger acquired Merak, a market leader in
petroleum software solutions; Secure Oil Tools, a leader in multilateral
completions; and substantially all of the assets of Panther Software
Corporation, a provider of hardware and software products and services for
managing large volumes of seismic data. These acquisitions were accounted for
using the purchase method of accounting. Costs in excess of net assets acquired
were $106 million which are being amortized on a straight-line basis over 7 to
20 years.

In the third quarter of 1999, the Omnes joint venture, created in 1995 between
Schlumberger and Cable & Wireless, was restructured into two separate business
units. Under the agreement, equal ownership and access to products, technology
and intellectual property was given to both parent companies. Schlumberger
retained ownership of the Omnes name. Omnes is now a fully operational company
within Test & Transactions.

On August 31, 1998, the merger of Schlumberger Technology Corporation, a wholly
owned subsidiary of Schlumberger, and Camco International Inc. was completed.
Under the terms of the merger agreement, approximately 38.2 million shares of
Camco common stock were exchanged for 45.1 million shares of Schlumberger common
stock at the exchange rate of 1.18 shares of Schlumberger stock for each share
of Camco. Based on the Schlumberger average price of $47-7/8 on August 28, the
transaction was valued at $2.2 billion. The business combination was accounted
for using the pooling-of-interests method of accounting.

During 1997, subsidiaries of Schlumberger acquired Interactive Video Systems,
Inc., a metrology solutions provider for the front-end semiconductor fabrication
equipment market, and S.A. Holditch and Associates, Inc., a petroleum and
geoscience consulting services company. These acquisitions were accounted for
using the purchase method of accounting. Costs in excess of net assets acquired
were $38 million which are being amortized on a straight-line basis over periods
of 5 and 15 years, respectively.

Investments in Affiliated Companies

In the third quarter of 1999, Schlumberger and Smith International Inc. entered
into an agreement whereby their drilling fluids operations were combined to form
a joint venture. Under the terms of the agreement, Schlumberger contributed its
non-US drilling fluids business and a total of $325 million to the joint
venture. Schlumberger owns a 40% interest in the joint venture and records
income using the equity method of accounting. The total investment on December
31, 1999 was $414 million. The equity income for 1999 is not material.

Investments

The Consolidated Balance Sheet reflects the Schlumberger investment portfolio
separated between current and long term, based on maturity. Except for $130
million of investments which are considered trading on December 31, 1999 ($125
million in 1998), it is the intent of Schlumberger to hold the investments until
maturity.

Long-term investments mature as follows: $133 million in 2001, $358 million in
2002 and $235 million thereafter.

On December 31, 1999, there were no interest rate swap arrangements outstanding
related to investments. Interest rate swap arrangements had no material effect
on consolidated interest income.

The decreases in cost and accumulated depreciation reflect the assets of the
Sedco Forex offshore contract drilling business, which was spun off on December
30, 1999 (see Discontinued Operations on page xx).

The estimated useful lives of Buildings & Improvements are primarily 30 to 40
years. For Machinery & Equipment, 13% is being depreciated over 16 to 25 years,
14% over 10 to 15 years and 73% over 2 to 9 years.

The majority of the long-term debt is at variable interest rates; the
weighted-average interest rate of the debt outstanding on December 31, 1999 was
5.9%. Such rates are reset every six months or sooner. The carrying value of
long-term debt on December 31, 1999 approximates the aggregate fair market
value.

Long-term debt on December 31, 1999, is due as follows: $92 million in 2001, $57
million in 2002, $2,322 million in 2003, $424 million in 2004 and $288 million
thereafter.

On December 31, 1999, interest rate swap arrangements outstanding were: pay
fixed/receive floating on US dollar debt of $600 million; pay floating/receive
fixed on US dollar debt of $214 million; pay fixed/receive floating on Japanese
yen debt of $107 million. Also outstanding on December 31, 1999 was a hedge in
the notional amount of $76 million against the US 10-year Treasury Note interest
rate. These arrangements mature at various dates to August 2008. Interest rate
swap arrangements had no material effect on consolidated interest expense in
1999 and no impact in 1998. The likelihood of nonperformance by the other
parties to the arrangements is considered to be remote.

Lines of Credit

On December 31, 1999, the principal US subsidiary of Schlumberger had an
available unused Revolving Credit Agreement with a syndicate of banks. The
Agreement provided that the subsidiary may borrow up to $1 billion until August
2003 at money market-based rates (6.1% on December 31, 1999) of which $375
million was outstanding on December 31, 1999; on December 31, 1998, there was no
outstanding amount. In addition, on December 31, 1999 and 1998, Schlumberger and
its subsidiaries also had available unused lines of credit of approximately $793
million and $630 million, respectively. Commitment and facility fees are not
material.

Capital Stock

Schlumberger is authorized to issue 1,000,000,000 shares of common stock, par
value $0.01 per share, of which 565,931,130 and 546,133,876 shares were
outstanding on December 31, 1999 and 1998, respectively. Schlumberger is also
authorized to issue 200,000,000 shares of cumulative preferred stock, par value
$0.01 per share, which may be issued in series with terms and conditions
determined by the Board of Directors. No shares of preferred stock have been
issued. Holders of common stock and preferred stock are entitled to one vote for
each share of stock held.

In January 1993, Schlumberger acquired the remaining 50% interest in the Dowell
Schlumberger group of companies. The purchase price included a warrant, expiring
in 7.5 years and valued at $100 million, to purchase 15,153,018 shares of
Schlumberger common stock at an exercise price of $29.672 per share. The warrant
was exercised by Dow Chemical on December 16, 1999.

Stock Compensation Plans

As of December 31, 1999, Schlumberger had two types of stock-based compensation
plans, which are described below. Schlumberger applies APB Opinion 25 and
related Interpretations in accounting for its plans. Accordingly, no
compensation cost has been recognized for its stock option plans and its stock
purchase plan. Had compensation cost for the stock-based Schlumberger plans been
determined based on the fair value at the grant dates for awards under those
plans, consistent with the method of SFAS 123, Schlumberger net income and
earnings per share would have been the pro forma amounts indicated below:

Stock Options Plans
During 1999, 1998, 1997 and in prior years, officers and key employees were
granted stock options under Schlumberger stock option plans. For all of the
stock options granted, the exercise price of each option equals the market price
of Schlumberger stock on the date of grant; an option's maximum term is ten
years, and options generally vest in 20% increments over five years.

As required by SFAS 123, the fair value of each grant is estimated on the date
of grant using the multiple option Black-Scholes option-pricing model with the
following weighted-average assumptions used for 1999, 1998 and 1997: Dividend of
$0.75; expected volatility of 25%-29% for 1999 grants, 21%-25% for 1998 grants
and 21% for 1997 grants; risk-free interest rates for the 1999 grants of
4.92%-5.29% for officers and 4.80%-6.25% for the 1999 grants to all other
employees; risk-free interest rates for the 1998 grant to officers of
5.59%-5.68% and 4.35%-5.62% for the 1998 grants to all other employees;
risk-free interest rates for 1997 grants of 6.19% for officers and 5.80%-6.77%
for all other employees; and expected option lives of 7.14 years for officers
and 5.28 years for other employees for 1999 grants, 6.98 years for officers and
5.02 years for other employees for 1998 grants and 7.27 years for officers and
5.09 years for other employees for 1997 grants.

Employee Stock Purchase Plan
Under the Schlumberger Discounted Stock Purchase Plan, Schlumberger is
authorized to issue up to 22,012,245 shares of common stock to its employees.
Under the terms of the Plan, employees can choose each year to have up to 10% of
their annual earnings withheld to purchase Schlumberger common stock. The
purchase price of the stock is 85% of the lower of its beginning or end of the
Plan year market price. Under the Plan, Schlumberger sold 1,324,848, 1,266,840
and 1,399,623 shares to employees in 1999, 1998 and 1997, respectively.
Compensation cost has been computed for the fair value of the employees'
purchase rights, which was estimated using the Black-Scholes model with the
following assumptions for 1999, 1998 and 1997: Dividend of $0.75; expected life
of one year; expected volatility of 40% for 1999, 34% for 1998 and 28% for 1997;
and risk-free interest rates of 5.33% for 1999, 4.44% for 1998 and 5.64% for
1997. The weighted-average fair value of those purchase rights granted in 1999,
1998 and 1997, was $19.829, $19.817 and $17.845, respectively.

Income Tax Expense
Schlumberger and its subsidiaries operate in more than 100 taxing jurisdictions
where statutory tax rates generally vary from 0% to 50%.

Schlumberger had net deductible temporary differences of $1.1 billion on
December 31, 1999 and $1.2 billion on December 31, 1998. Significant temporary
differences pertain to postretirement medical benefits, fixed assets, employee
benefits and inventory.

The components of consolidated income tax expense from continuing operations

For the three years, the variations from the US statutory federal tax rate (35%)
and Schlumberger effective tax rates were due to several factors, including the
effect of the US operating loss carryforward in 1997 and a substantial
proportion of operations in countries where taxation on income is lower than in
the US.

In the third quarter of 1996, with increasing profitability and a strong outlook
in the US, Schlumberger recognized 50% of the US income tax benefit related to
its US subsidiary's tax loss carryforward and all temporary differences. This
resulted in a credit of $360 million. In the second quarter of 1997,
Schlumberger released the remaining valuation allowance related to its US
subsidiary's tax loss carryforward and all temporary differences. The resulting
reduction in income tax expense was not significant.

Leases and Lease Commitments

Total rental expense was $303 million in 1999, $304 million in 1998 and $265
million in 1997. Future minimum rental commitments under noncancelable leases
for years ending December 31 are: $111 million in 2000; $99 million in 2001; $86
million in 2002; $62 million in 2003; and $52 million in 2004. For the ensuing
three five-year periods, these commitments decrease from $79 million to $4
million. The minimum rentals over the remaining terms of the leases aggregate to
$43 million.

Contingencies

The Consolidated Balance Sheet includes accruals for the estimated future costs
associated with certain environmental remediation activities related to the past
use or disposal of hazardous materials. Substantially all such costs relate to
divested operations and to facilities or locations that are no longer in
operation. Due to a number of uncertainties, including uncertainty of timing,
the scope of remediation, future technology, regulatory changes and other
factors, it is possible that the ultimate remediation costs may exceed the
amounts estimated. However, in the opinion of management, such additional costs
are not expected to be material relative to consolidated liquidity, financial
position or future results of operations.

In addition, Schlumberger and its subsidiaries are party to various other legal
proceedings. Although the ultimate disposition of these proceedings is not
presently determinable, in the opinion of Schlumberger any liability that might
ensue would not be material in relation to the consolidated liquidity, financial
position or future results of operations.

Segment Information

Schlumberger operates three reportable segments: Oilfield Services (OFS),
Resource Management Services (RMS) and Test & Transactions (T&T).

The Schlumberger OFS segment falls into four clearly defined economic and
geographical areas and is evaluated on the following basis: First, North America
(NAM) is a major self-contained market. Second, Latin America (LAM) comprises
regional markets that share a common dependence on the United States. Third,
Europe is another major self-contained market that includes West Africa and the
CIS, whose economy is increasingly linked to that of Europe. Fourth, Other
Eastern includes the remainder of the Eastern Hemisphere, which consists of many
countries at different stages of economic development that share a common
dependence on the oil and gas industry. Camco is managed as a separate unit
within OFS.

The OFS segment provides virtually all exploration and production services
required during the life of an oil and gas reservoir. Schlumberger believes that
all the products/services are interrelated and expects similar performance from
each. The RMS segment is essentially a global provider of measurement solutions,
products and systems for electricity, gas and water utilities worldwide. The T&T
segment supplies technology products, services and system solutions to the
semiconductor, banking, telecommunications, transportation and health care
industries. The segment consists of Automated Test Equipment, Smart Cards &
Terminals and Omnes. Services and products are described in more detail on page
xx of this report.

Corporate assets largely comprise short-term and long-term investments.

During the three years ended December 31, 1999, no single customer exceeded 10%
of consolidated revenue.

The accounting policies of the segments are the same as those described in
Summary of Accounting Policies.

Oilfield Services' net income eliminations include: certain headquarters
administrative costs which are not allocated geographically, goodwill
amortization, and certain costs maintained at the OFS level.

Nonoperating expenses, such as certain intersegment charges and interest expense
(except as shown above), are not included in segment operating income.

Schlumberger did not have revenue from third-party customers in its country of
domicile during the last three years. In each of the three years, only revenue
in the US exceeded 10% of consolidated revenue. Revenue in the US in 1999, 1998
and 1997 was $2.5 billion, $3.4 billion and $3.5 billion, respectively.

Pension and Other Benefit Plans

US Pension Plans
Schlumberger and its US subsidiary sponsor several defined benefit pension plans
that cover substantially all employees. The benefits are based on years of
service and compensation on a career-average pay basis. These plans are fully
funded with a trustee in respect to past and current service. Charges to expense
are based upon costs computed by independent actuaries. The funding policy is to
annually contribute amounts that are allowable for federal income tax purposes.
These contributions are intended to provide for benefits earned to date and
those expected to be earned in the future.

The assumed discount rate, compensation increases and return on plan assets used
to determine pension expense in 1999 were 7%, 4.5% and 9%, respectively. In
1998, the assumptions were 7.5%, 4.5% and 9%, respectively. In 1997, the
assumptions were 8%, 4.5% and 8.5%, respectively.

The assumed discount rate, the rate of compensation increases and the expected
long-term rate of return on plan assets used to determine the projected benefit
obligations were 7.75%, 4.5% and 9%, respectively, in 1999, and 7%, 4.5% and 9%
respectively, in 1998. Plan assets on December 31, 1999, consisted of common
stocks ($843 million), cash or cash equivalents ($152 million), fixed income
investments ($197 million) and other investments ($84 million). Less than 1% of
the plan assets on December 31, 1999, were represented by Schlumberger common
stock.

Non-US Pension Plans
Outside the US, subsidiaries of Schlumberger sponsor several defined benefit and
defined contribution plans that cover substantially all employees who are not
covered by statutory plans. For defined benefit plans, charges to expense are
based upon costs computed by independent actuaries. These plans are
substantially fully funded with trustees in respect to past and current service.
For all defined benefit plans, pension expense was $19 million, $17 million and
$15 million in 1999, 1998 and 1997, respectively. The only significant defined
benefit plan is in the UK.

The assumed discount rate, compensation increases and return on plan assets used
to determine pension expense in 1999 were 7%, 4% and 9%, respectively. In 1998,
the assumptions were 7.5%, 5% and 9%, respectively. In 1997, the assumptions
were 8%, 5% and 8.5%, respectively.

For defined contribution plans, funding and cost are generally based upon a
predetermined percentage of employee compensation. Charges to expense in 1999,
1998 and 1997, were $24 million, $25 million and $25 million, respectively.

Other Deferred Benefits
In addition to providing pension benefits, Schlumberger and its subsidiaries
have other deferred benefit programs. Expenses for these programs were $73
million, $128 million and $127 million in 1999, 1998 and 1997, respectively.

Health Care Benefits
Schlumberger and its US subsidiary provide health care benefits for certain
active employees. The cost of providing these benefits is recognized as expense
when incurred and aggregated $53 million, $54 million and $46 million in 1999,
1998 and 1997, respectively. Outside the US, such benefits are mostly provided
through government-sponsored programs.

Postretirement Benefits Other Than Pensions
Schlumberger and its US subsidiary provide certain health care benefits to
former employees who have retired under the US pension plans.

The principal actuarial assumptions used to measure costs were a discount rate
of 7% in 1999, 7.5% in 1998 and 8% in 1997. The overall medical cost trend rate
assumption beginning December 31, 1996, was 9% graded to 5% over the next six
years and 5% thereafter. Previously the overall assumption had been 10% graded
to 6% over the next six years and 6% thereafter.

Net periodic postretirement benefit cost in the US for 1999, 1998 and 1997,

The assumed discount rate used to determine the accumulated postretirement
benefit obligation was 7.75% for 1999 and 7% for 1998.

If the assumed medical cost trend rate was increased by one percentage point,
health care cost in 1999 would have been $39 million, and the accumulated
postretirement benefit obligation would have been $372 million on December 31,
1999.

If the assumed medical cost trend rate was decreased by one percentage point,
health care cost in 1999 would have been $26 million, and the accumulated
postretirement benefit obligation would have been $278 million on December 31,
1999.
