Energia Ltd. and Oando Energy Resources Inc., Calgary, tested 49° gravity oil at the rate of 2,400 b/d on a 28/64-in. choke from a second zone at the EB-4 well in Ebendo marginal field on OML 56 in the central onshore Niger Delta in Nigeria.
The second zone tested, Level XIX, was the well’s primary target and is also the zone producing 2,100 b/d in the EB-1 well.
EB-4 is being dually completed with Level XIX being produced from the short string and Level XXa producing from the long string. Level XXa tested up to 950 b/d of oil. Both strings are to be tied into the existing Ebendo Production Facility and will be put on stream as soon as the rig is skidded to the EB-5 well location.
EB-5 is intended to appraise the intermediate hydrocarbon bearing sands, Levels XV to XVIII, encountered while drilling the EB-4 well.
EB-4 well was spudded on Mar. 24 and drilled to 12,120 ft measured depth. Intended to appraise the updip part of the structure, it encountered eight new hydrocarbon bearing sands over an interval from 9,667 ft to 11,182 ft, each with reservoir thicknesses of 21-110 ft. The eight zones were in addition to Level XIX, the producing sand target.
