Nigeria's Oil & Gas Fields - Erha & Erha North.
Apart from the two JVs, ExxonMobil has PSCs for offshore tracts, where water depths exceed 1,000 metres. These include Erha and its northern satellite in the west of the delta, which Mobil found in 1999. In this ExxonMobil holds 56.25% and Shell has 43.75%. Erha went on stream in March 2006 and reached a peak of 200,000 b/d in July 2006. Crude oil from Erha is stored in a FPSO vessel, built by Bouygues Offshore under a $700m contract with capacity of 2.2m barrels. VLCCs of up to 300,000 dwt take the crude. Erha is in 1,200 metres of water. Erha North went on stream in late 2006.
The $3.5 bn Erha and Erha North developments consist of 32 subsea wells tied to the FPSO vessel. Associated gas production, 300 MCF/d, is reinjected for reservoir management. ExxonMobil's Esso Exploration and Production Nigeria Ltd (Esso) operates Erha and Erha North. Erha North's Phase-II, 30,000 b/d, is to be on stream in 2012/13.
MPN in mid-2008 completed the $1.3bn East Area NGL-II project yielding 275m barrels of NGL from associated gas produced in East Area reservoirs from OML-67, 68 and 70. This includes an offshore NGL extraction complex, more than 200 km of gas and NGL pipelines and expansion of the onshore Bonny River Terminal's fractionator for sales liquids and offloading. This is part of an integrated approach to greatly reduce flaring in conjunction with the East Area Additional Oil Recovery project. East Area NGL-II will peak at 50,000 b/d NGL. It is to use 950 MCF/d gas. The project is about 28 km off the coast and on Bonny Island. MPN holds 51% and NNPC has 49% in this project.
Bosi field went on stream in mid-2008 at 110,000 b/d, to reach 135,000 b/d in 2011.
Esso in May 2006 made a big oil find in OPL214. Uge-1 was drilled in 1,263 metres of water to a depth of 16,831 ft (5,130m) and encountered more than 300 net ft of oil. Uge is about 145 km south-south-east of Erha. Transocean's Deepwater Pathfinder drilled the well. Esso is the operator with 20%. Its partners are Chevron (20%), ConocoPhillips (20%, Oxy (20%), NPDC (15%) and Sasol (5%).
In mid-2006, Sr ExxonMobil VP Stuart McGill said: "Liquids productionExxonMobil [units] either operate or participate in offshore Nigeria currently exceeds 1.1m b/d" (see background in gmt6NigrFieldsAug6-07).
