Item 5. Other Events
The company's Spirit Energy 76 business unit has participated in an oil and gas
discovery on the Mad Dog prospect in the Gulf of Mexico deepwater Green Canyon
block 826. The well encountered 300 net feet of hydrocarbons, primarily crude
oil. Although further appraisal drilling is required to determine the full
extent of the discovery, the company believes the find to be significant.
Spirit Energy 76 holds a 25-percent interest in the 2-1/2-block drilling unit
that encompasses most of the Mad Dog structure. The drilling unit is located in
5,000 to 7,000 feet of water in Green Canyon blocks 825, 826 and 782, about 150
miles southwest of Venice, La. The well spudded in May 1998 and was drilled to a
total depth of 22,410 feet. The pay zones were sampled, but not tested. BP Amoco
p.l.c. is the operator of the Mad Dog well.
Mad Dog is the second deepwater discovery announced by Spirit Energy 76 this
year. In March, Spirit Energy 76 and Vastar Resources Inc., announced a
discovery on the Mirage prospect in Mississippi Canyon block 941.
The company has also reached an agreement with Conoco Inc. to acquire a
50-percent working interest in the oil and gas lease covering Green Canyon Block
562 which encompasses the K2 prospect. The K2 prospect is located just north of
Mad Dog on the same geologic trend.
Forward-looking statements regarding exploration activities and resource
potential in this filing are based on assumptions concerning market,
competitive, regulatory, environmental, operational and other considerations.
Actual results could differ materially as a result of factors discussed in
Unocal's 1998 Form 10-K report filed with the Securities and Exchange
Commission.
