In late July 2018, Eland Oil & Gas plc, part of the Joint Venture Elcrest Exploration and Production Nigeria Ltd (Eland Oil & Gas 45% and Starcrest Nigeria Energy Ltd 55%) was completing Opuama 10 in OML 40, using OES âTeamwork Rigâ. The company will now test D1000 and D5000 reservoirs (main targets) in Opuama 10 with a Maximum Efficient Test (MER Test) before being put onstream. With this well, a daily production of 30,000 bo is targeted from the field. To date, Opuama is the only productive oil field in OML 40 and it is located onshore in the northwestern Niger Delta.

All were discovered between the early 1970s and the early 1990âs. There are also a number of potential prospects and leads within the acreage that could increase prospective resources (e.g. Polobo East and Tsekelewu Northwest). 2P recoverable reserves for OML 40 are estimated to reach 197 MMbbl of oil and 316 Bcf of gas, half of it comes from the Opuama field.  OML 40 covers 484 sq km. It is located north of Chevronâs OML 49, which has extensive production and export infrastructure connected to the Escravos terminal. Elcrest holds 45% operated interests in OML 40, whereas the Nigerian National Petroleum Co remains the balance (55%).
Opuama 10 pos. appr. (Eland 45% op, NNPC 55%) in OML 40 block, encountered six oil bearing reservoirs, with significant amounts of net pay of 93,5m, TD=2476m.
