Background
The Ebok Field (Ebok) was awarded to Oriental in May 2007 by the ExxonMobil / Nigerian National Petroleum Corporation (NNPC) Joint Venture. The farm-out was structured such that the field benefits from the Nigerian Marginal Field Fiscal and Tax Regime.
Ebok is an undeveloped oil field located in OML 67, 50 km offshore in 135 ft of water in Nigeria's prolific south eastern producing area. The field was discovered by the ExxonMobil / NNPC JV in 1968 (M-QQ1 (Ebok-1)), and two subsequent appraisal wells were drilled in 1970 (Ebok-2 and Ebok-3). A total of 271 ft. (83m) of net oil pay was encountered in Ebok-1 in four sands between 2,600 ft. (800m) and 3,600 ft. (1,100m); none of the zones were production tested although 24°API oil was recovered from the Ebok- 1 well.
The Ebok area is covered with good quality (1992) 3D seismic data and an extensive data set is available for all well drilled to date. Ebok is also located close to several producing ExxonMobil / NNPC JV fields and 55 km south-east of ExxonMobil’s onshore QIT Terminal. The initially estimated mean STOIIP at Ebok (pre 2008/2009 appraisal drilling) was 118 mmbbls of which 25 mmbbls was estimated as recoverable by the Company.
Strong production performance
Gross production at the Ebok field was 35,102 bopd during the period to 30th September 2013, representing a year-on-year increase of 22 per cent.
During the period the Partners successfully drilled three production wells at the field, two from the North Fault Block (NFB) and one from the West Fault Block (WFB); the wells are producing at an average rate of approximately 3,925 bopd. A water injector well will be spudded shortly to optimise and support the existing producing wells on the North Fault Block.
Creating a production hub offshore south-east Nigeria
Our development strategy is to systematically bring each proven area of the Ebok field onstream and, through ongoing drilling, continue to increase the reserves base from the field over the coming months and years. We plan for the MOPU and FSO to become a central facility, not just for the immediately surrounding Ebok structure, but also for the broader Ebok/Okwok/OML 115 area. This will facilitate the economical and rapid tie-back of production from potential future developments on the acreage.
Outlook
The Central Fault Block Extension platform is expected to be installed in early 2014, and will target additional reservoirs in the Central Fault Block. The Partners are looking at development options for the NFB, which would likely involve the drilling of development wells from an extended WFB platform and with production achieved through to the existing MOPU.
