Offshore staff
(West Africa) - Peak Petroleum Industries Nigeria Ltd. and Equator Exploration Ltd. have compled operations with successful production flow tests on the B-DX1 well, located on OML 122, offshore Nigeria.
The OML 122 license area is located 25 - 60 km offshore in water depths of 40 - 300 m and covers an area of 1,295 sq km on the Western Niger Delta, east of the Bonga field (estimated 1.4 Bbbl) on OML 218 and southwest of EA field on OML 79.
B DX1 is an exploratory-appraisal well on one of the discoveries made in OML 122 in the 1970s.
Production flow testing of a selected perforated interval (2314-24 m subsea) in the main gas reservoir is now complete.
After a clean-up period and a multi-flow test, the well was flowed for 12 hours on a 56/64-in.choke. A stabilied rate of 26.5 MMcf/d was achieved with a wellhead flowing pressure of 1,682 psig.
Subject to further drilling, the independent technical advisers to Equator, Horizon Energy Partners BV estimate the oil-in-place to be 130 MMbbl.
They estimate the total gas-in-place in the zones that could be evaluated to be 900 bcf, not including the deep gas zone penetrated but not evaluated because of its high pressure.
Production testing and wireline logging information indicate that all of the reservoir horizons, which are located in the paralic sequence in the Agbada formation, have excellent properties.
Peak and Equator continue engineering work on a scheme for the immediate development of the oil reservoir based on subsea horizontal wells and an FPSO.
Orders for long-lead time equipment are being placed. and negotiations for a suitable FPSO continue.
Subject to further engineering, reservoir evaluation, and drilling, it is anticipated that oil production could begin in the first half of 2007.
Equator is funding the cost of two wells in the field to earn a 40% economic interest in the field area.
The B-DX1 well has been suspended for later oil production service and the rig is now being moved 18 miles to the south to the second location in the OML 122 drilling campaign.
In the next few days it will spud Owanare AX1 on the Owanare prospect, which lies in a water depth of 135 m.
The 3D seismic data covering the prospect has been re-processed and interpreted by Peak, Equator, and its independent technical advisors, Horizon, indicating that Owanare has undiscovered gas-in-place in excess of 3 tcf.
The aim of the initial two wells being drilled by Peak/Equator is to prove-up significant volumes of gas as potential supply for the numerous gas-utilization projects currently underway or in planning stages in Nigeria within close proximity to OML 122.
A secondary objective is to find commercial volumes of oil and condensate on the block.
Additional appraisal and development wells will follow the drilling of the Owanare prospect.
