Esso Exploration and Production Nigeria Limited

The Company was awarded a Production Sharing Contract by the Nigerian National Petroleum Corporation (NNPC), for Oil Prospecting Lease (OPL) 209 (now OML 133) that same year.

EEPNL is operator of the deepwater oil and gas development named Erha. The field streamed first oil in the first half of 2006.

In December 1999, EEPNL, announced confirmation of the Erha major deepwater oil and gas discovery on OPL Block 209 in 1,000 meters water depth. The confirmation well was drilled to a depth of 3,745 meters and flow tested as an oil-bearing reservoir at a test rate of 2,800 barrels per day. In 2000, EEPNL completed development planning for the Erha field development located about 100 kilometers off the coast of Nigeria. The Erha main development has capacity to produce an annual average of 150,000 barrels of oil and process 315 MMSCF of natural gas per day. OML 133 deepwater block is expected to recover about 500 million barrels of oil.

EEPNL has a 56 percent participating interest in the OML 133 contract area, while co-venturer SNEPCO holds the remaining 44 percent share.

In addition to OML 133, another ExxonMobil affiliate owns 20 percent interest in the Bonga development on OML 118 located in greater than 1,200 meters water depth. Bonga was discovered in 1996. The initial project is expected to recover 560 million barrels of oil and commenced production of about 200,000 barrels per day from subsea manifolds tied to a FPSO in 2004. The same OML also contains the recently discovered Bonga SW accumulation, which from early interpretations appears to have significant production potential.
