Unocal hydrocarbon discoveries offshore Indonesia
show significant oil and gas potential in deepwater areas
---------------------------------------------------------
El Segundo, Calif., Sept. 16, 1997 -- Unocal Corporation today said
that its Unocal Indonesia Company subsidiary and Mobil Makassar, Inc., have
successfully tested a discovery well offshore East Kalimantan, Indonesia, that
establishes significant natural gas and oil production potential in the
deepwater area of the Mahakam Delta.
The discovery well, Merah Besar #6, was drilled in 2,284 feet (703
meters) of water to earn Unocal a 50-percent working interest in the Makassar
Strait Production Sharing Contract (PSC) area. Unocal announced last year the
signing of agreements with Mobil Makassar to acquire an interest and assume
operatorship under the Makassar Strait PSC, which is adjacent to Unocal's
existing East Kalimantan contract area. Mobil Makassar holds the remaining 50
percent working interest.
This latest discovery follows six other successful deepwater
exploration wells that have been drilled in Unocal's existing East Kalimantan
contract area as part of its current exploration program. Unocal holds a 100
percent working interest in the East Kalimantan production sharing contract
area.
The Merah Besar #6 well tested at a rate of 24.8 million cubic feet of
gas and 860 barrels of condensate per day on a 48/64-inch choke from a single
zone. Two other zones tested at a combined rate of 980 barrels of oil per day.
"These discoveries demonstrate there is significant hydrocarbon
potential in this deepwater area offshore East Kalimantan," said Timothy C.
Lauer, president and managing director of Unocal Indonesia. "Once we confirm the
commerciality of these discoveries, we will be able to rapidly bring the new
fields on production through our existing major infrastructure network in the
area." The company said that it expects gas production from this area would be
processed through the Pertamina's Bontang liquefied natural gas facility.
Unocal and Mobil Makassar now plan extensive seismic data acquisition,
exploration drilling, and testing to evaluate the production potential of the
discoveries. Three-dimensional seismic acquisition on the Makassar Strait PSC
area has already started.
Lauer noted that Unocal expects to build on its record of technical
innovation in Indonesia to accelerate production of new commercial discoveries
quickly and efficiently. Unocal made Indonesia's first subsea well completion,
conducted the first exploration 3D seismic survey, installed the deepest water
depth platform and developed the stacked-template structure (STS) for rapid,
low-cost field development.
Unocal Indonesia, under a production sharing contract with Pertamina,
the Indonesian national oil company, operates nine fields offshore East
Kalimantan. Unocal holds a 100-percent working interest in eight of these fields
- -- Santan, Serang, Sepinggan, Melahin, Kerindingan, Seguni, Pantai and Yakin --
and a 50-percent working interest in the supergiant Attaka field. Current gross
daily production is more than 90,000 barrels of oil and 250 million cubic feet
of gas. All of the production is in water depths of less than 300 feet (100
meters).
Unocal Corporation is one of the world's leading energy resource and
project development companies, with reserves of more than 9.8 trillion cubic
feet of natural gas equivalent (1.6 billion barrels of oil equivalent) and major
oil and gas production activities in Asia and the U.S. Gulf of Mexico. The
company maintains headquarters in both California and Malaysia.
