HOUSTON, Oct. 4 -- A Total SA subsidiary, Elf Petroleum Nigeria Ltd., extended western Usan field in Oil Prospecting License 222 off southeastern Nigeria.
The Usan 5 well, 110 km off Nigeria, is in 750 km of water, 6 km west of the Usan 4 discovery well. Usan 5 is the fourth successful appraisal for the field, which was discovered in 2002 (OGJ Online, June 10, 2002).
"Oil was sampled at Usan 5 in several levels, confirming the presence of additional quantities of oil as well as further potential in previously untested reservoirs," Total said.
OPL 222 concessionaire is Nigerian National Petroleum Corp. under a production-sharing contract operated by Elf Petroleum Nigeria, which holds 20% interest.
