Afren plc issued an update of its activities across Africa, including Nigeria in its Interim Management Statement for the first nine months ending September 30. At the Ebok field, the company saw gross production average 27,277 bpd during the period. Adverse weather conditions have delayed the installation of the CFB extension platform and the planned three producers targeting additional reservoirs in the CFB. The installation of the CFB extension platform is now expected to complete in Q4 as soon as the weather conditions permit. Batch drilling from the North Fault Block (NFB) targeting three producers and one water injector in 2014 continues to make good progress with one producer currently onstream which has tested at rates as high as 5,000 bpd and production from the second well is to start imminently.
Production operations continue to run smoothly at the Okoro field where gross production at the field averaged 16,184 bpd in the period, incorporating planned downtime earlier in the year. As part of the development program at Okoro this year, the Okoro-15 producer was completed and brought onstream in September at a rate of 2,000 bpd. The planned second producer, Okoro-12 ST1 was brought onstream late October and is also expected to produce approximately 2,000 bpd.
Afren reported that the partners sanctioned the FID for the Okoro Further Field Development. The rig for the Mobile Offshore Platform Unit (MOPU) has been procured and is on its way to the construction yard in Singapore. Construction of the wellhead platform has commenced and is expected to complete by March 2015. The wellhead platform will be installed at the field during Q2 2015 with development drilling commencing shortly thereafter.
At Okwok, the wellhead jacket has been fabricated and is currently awaiting installation and is expected to be completed in Q4 2014 prior to development drilling.
On OML 26, following Field Development Plan approval, the first of the five new wells, Ogini-22, was spud in late July 2014. Ogini-22 achieved a horizontal drain hole of 1,342 ft length within a total depth of 9,940 ft with initial test results indicating a production rate of over 2,300 bpd. The second well is underway and the partners expect to complete this shortly. Following this, a third producer will be spud prior to year end and it is expected that it will come onstream in January 2015. The LACT unit is undergoing Site Acceptance Testing (SAT). Estimated volumes delivered prior to commissioning and SAT of the LACT unit are subject to reconciliation and agreement with Shell which is expected after SAT is completed.
In October the JV partners on OML 113 sanctioned the FID for the first phase of the Cenomanian development in the Aje field that will include two subsea production wells tied back to a leased FPSO. First oil from the Aje field is expected late 2015.
The company saw the processing of the 2,716 sq km of marine 3D seismic data acquired across OPL 310 in H1 2014 and seismic acquisition on OML 113 is ongoing and the fast track post stack time migration from the survey was delivered in August. The final production pre-stack time migration will be delivered in late Q4 2014 and the pre-stack depth migration is due in Q1 2015. The interpretation of these data-sets will be used to finalize a well location. Various rig options are being investigated for appraisal drilling in 2015.
The data from the seismic campaign will also assist with the Phase 2 development on Aje (OML 113) and to further de-risk the exploration potential over the whole block, including the syn-rift exploration potential following the discovery at Ogo in 2013. The first exploration well to be drilled by the Afren-Oriental JV in Nigeria this year will be the Ebok deep exploration tail planned for Q4 2014, targeting the deeper Qua Iboe and Biafra reservoirs. The exploration tail will be targeting gross Pmean resources of 50 million barrels.
On OML 115, preparations are underway for the drilling of the Ameena East prospect, scheduled to spud in November 2014, using the Adriatic I rig. The Ameena East-1 exploration well will be targeting gross Pmean resources of 65 million barrels, in Biafra sands below the regional basal Qua Iboe unconformity.
