More zones have flowed oil, condensate, and gas at hefty rates in the western Gulf of Guinea off Cote d'lvoire.
United Meridian Corp., Houston, reported the rates in connection with the completion of tests at its 1 Lion well on Block CI 11.
UMC and its partners plan to start an 8,500 sq km 3D seismic program this month to supplement the original seismic data and better define development drilling locations at Lion and at UMC's Panthere prospect 3 miles east of 1 Lion.
Meanwhile, Mobil Equatorial Guinea Inc. will participate in a well to be drilled by UMC off Equatorial Guinea late this year.
COTE D'IVOIRE TESTS
UMC has installed a guyed tower platform to produce its 1 Lion well and also tied in the B1 8X well drilled and successfully tested by Phillips Petroleum Co. in the early 1980s (see map, OGJ, Apr. 4, p. 69).
A UMC led group submitted a preliminary development plan to the Cote d'Ivoirian government. The company said production depends on numerous contingencies but is expected to start in 1995.
UMC in late April announced that four new zones at 8,671 10,166 ft flowed at a combined rate of 9,433 b/d of oil and condensate and 54 MMcfd of gas.
These tests were in addition to the well's three deeper tests, previously announced in March, which flowed a combined 14,263 b/d of oil and 11 MMcfd of gas. None of the tests revealed water.
The 1 Lion encountered about 205 ft of net pay overall. The deeper tests were:
At 10,176 234 ft, 4,063 b/d of oil and 3.5 MMcfd of gas through a 7/8 in. choke with 655 psi flowing tubing pressure.
At 10,258 348 ft, 5,875 b/d of oil and 4 MMcfd of gas through a 1 in. choke with 701 psi flowing tubing pressure.
At 10,368-407 ft, 4,325 b/d of oil and 3.3 Mmcfd of gas through a 1 in. choke with 508 psi flowing tubing pressure.
The 1 Lion is 8 miles offshore in 234 ft of water 60 miles southwest of Abidjan. It is 3 miles west of UMC's 1 Panthere discovery, which flowed 30 MMcfd of gas and 732 b/d of condensate in late 1993.
UMC owns 25% and 28% interests, respectively, in the Lion and Panthere prospects. Other working interest owners are the national oil company Petroci with 40% of Lion and 10% of Panthere, International Finance Corp. 15% and 26%, Global Natural Resources Corp. 10% and 18%, and Pluspetrol SA 10% and 18%.
EQUATORIAL GUINEAMobil plans to earn a 65% interest in a production sharing contract covering LWC's 547,000 acre Block B southwest of Alba gas field (see map, OGJ, May 7, 1990, p. 56).
Mobil will participate in a well UMC is to operate during fourth quarter 1994 on UMC's Delta 1 prospect.
Block B is adjacent to the prolific oil producing areas of Nigeria, where Mobil has gained technical strength in deepwater drilling.
UMC completed a $4 million seismic program last year that defined numerous large prospects on Block B and on 438,000 acre Block A southeast of Alba field. UMC entered the second contract phase, which calls for the drilling of one well on each block.
UMC said it plans to drill the Dorado prospect on Block A in second half 1994 to test extensive bright spot amplitudes found as shallow as 6,750 ft.
