Oriental Energy, Afren Energy complete first devt oil well

19 June 2015, Lagos – Oriental Energy Resources Limited (OERL) and its JV Partners, Afren Energy Resources and Addax Petroleum have announced the completion and flow testing of their first development well, Okwok 13 in the Okwok marginal field in OML 67.


The companies stated that the completion followed an extensive field appraisal programme, the acquisition and processing of a 4-component OBC seismic and the approval of the Field Development Plan (Okwok FDP) by the Department of Petroleum Resources (DPR) in early 2014.

It was learnt in a statement issued on Thursday, that the Okwok-13 development well was drilled in early 2015 to a total measured depth of 9,002 feet and was  completed as a horizontal producer in the LD-1B Lower reservoir with over 1500ft pay section.

According to the statement, “Following the completion, the well was successfully tested to reconfirm commercial deliverability and reservoir connectivity.

“A facility-constrained rate of 5,400bopd, 24.5 deg API was tested on 36/64 choke with GOR of 355scf/bbl and wellhead pressure of 1,248psi. The test data showed no evidence of depletion and preliminary analysis indicates significant reserves addition is confirmed by this well.”

They noted that the well would be suspended in readiness for regular production when the planned Mobile Offshore Production Unit (MOPU) and the Okwok crude oil sales export pipeline are installed.

The Okwok wellhead jacket was installed in late 2014 and “this permitted the drilling of this first development well.” The pipeline to transport Okwok processed crude over the 15kilometre distance to Oriental’s Ebok Terminal has been procured and is currently awaiting installation.

The statement quoted the Oriental Chairman, Alhaji Muhammadu Indimi, as saying: “I am extremely pleased with the results of the testing of the Okwok-13 well at a rate over 5000 barrels per day of quality Nigerian crude oil, as it further confirms the commercial viability of the Okwok Field.

“The company looks forward to bringing Okwok production online within a short time. Produced Okwok crude will be stored for export in the Ebok Terminal Floating Storage and Offloading (FSO) Veer Prem operated by the Oriental JV.”

Okwok is the second asset that Oriental and its partners are developing under Farmout from ExxonMobil. The Oriental JV also operates the nearby EbokField development where a number of major technological innovations were deployed.

The Ebok field currently produces over 30,000 bopd and is believed to be the largest offshore ESP operation in Africa.

Founded in 1991, Oriental Energy Resources Limited appreciates the opportunity provided by the federal government with the support of the DPR to be an Indigenous Upstream Exploration and Production operator and the company disclosed that it is proud to be among the leaders in this laudable programme.
