Oando Energy Resources Incorporated yesterday announced the well test results of the EB-4 well’s second zone (Level XIX), which yielded 2,400 bopd of 49 degree API oil using a 28/64” choke.
The result according to the oil company “concludes a successful drilling programme and well tests on the two strings encountered.”
It said the Level XIX was the primary target for this well and is also the zone currently producing 2,100 bopd on a 28/64” choke in the EB-1 well.
“The EB-4 well is being completed as a dual-string producer, with Level XIX being produced from the short string and Level XXa producing from the long string. As was announced on August 13, 2012, Level XXa tested up to 950 bopd. Both strings are to be tied into the existing Ebendo Production Facility and will be put on stream as soon as the Drilling Rig skids to the next well (EB-5). The EB-5 well is intended to appraise the intermediate hydrocarbon bearing sands (Levels XV to XVIII) encountered during the drilling of the EB-4 well,” the company said.
However, it explained that the EB-4 well was spud on March 24, 2012 and was drilled to a total depth (TD -0.31 per cent, news) of 12,120ft measured depth (MD -0.67 per cent, news) on June 11th, 2012.
The well, which was intended to appraise the updip portion of the structure, encountered eight new hydrocarbon bearing sands over an interval from 9,667ft to 11,182ft, each with individual reservoir thicknesses of between 21ft and 110ft. These eight new sand zones were in addition to Level XIX, the producing sand target. These test results may not necessarily be indicative of the well’s long-term production performance or of ultimate recovery.
