Oando Energy Resources has announced the completion and testing of the Ebendo 5 well, which is expected to contribute additional 2,500 barrels of oil per day (bpd) from the field.

The development, according to a statement from the company, followed the successful resumption of 3,200 bpd gross production on the Ebendo field.

The Chief Executive Officer of OER, Pade Durotoye: “We’re extremely pleased to announce the successful completion of the Ebendo 5 well drilling programme, increasing our net capacity by 1,069 bpd.

“Ebendo currently has a total production capacity of up to 7, 000 bpd, but is currently subject to take away capacity restrictions as a result of the Kwale-Akri pipeline.

“In light of this, we are increasing our efforts to establish our alternative evacuation pipeline, the 53 kilometre, 45kboepd Umugini pipeline, that will further support the development of this field and reduce our dependence on one evacuation pipeline,” he said.

The Ebendo 5 well was spudded as a deviated appraisal/development well on October 12, 2012, mainly to appraise the intermediate reservoirs encountered by the earlier Ebendo 4 well.

The statement explained: “The Ebendo 5 well was drilled to a total vertical depth (TVD) of 11,513ft and encountered eight hydrocarbon bearing sands. A drill stem test was successfully completed on two of the sands (XVIIIc and XVIIId). Sand XVIIId flowed for 18 hours and 30 minutes during the final flow test on four choke sizes.

“On average, it flowed on choke 28/64”for three hours and 30 minutes, with an average oil and gas rate of 1,592 bpd and 2.45 mmscfpday, respectively. Sand XVIIIc flowed for 15 hours and 50 minutes during the final flow test on three choke sizes. On average, it flowed on choke 24/64” for eight hours and 23 minutes, with an average oil and gas rate of 840 bpd and 4.62 mmscfpday, respectively.

“Oil with API gravities of 47.2 degrees and 46.4 degrees were recovered from levels XVIIIc and XVIIId, respectively. Testing of sand XV is planned to occur during production, as there was a mechanical failure during testing of this sand after the completion of the well. However, from Modular Formation Dynamic Testing (MDT) pressure sampling, the fluid gradient in level XV was 0.272 pressure per foot (psi/ft), which is indicative of oil, there was no appreciable steady decline in the pressures during the Test.

“The Ebendo 5 well was dually completed and sand XV will be produced through the short string while sands XVIIIc and XVIIId will be produced through the long string via a sliding sleeve. The Acme Rig-5 was released on April 17, 2013 from the Ebendo 5 well site.”

The company further announced that a new rig, the Deutag T-26, has been mobilised and a sixth well (the Ebendo 6 well) was spudded on April 18, 2013.

TVD for the Ebendo 6 well is planned to be at 10,680 ft. To date, the Ebendo 6 well has been drilled to a total vertical depth of 6,231 ft. The results from this drilling programme will enable further appraisal of the shallow reservoirs encountered in the last two wells.

As pressure transient analysis or well-test interpretation has not been carried out, all results disclosed in this press release should be regarded as preliminary and are not necessarily indicative of long-term performance or ultimate recovery. The results will be updated when additional data becomes available.

Oando Energy Resources Inc. (OER) currently has a broad suite of producing, development and exploration properties in the Gulf of Guinea with current production of approximately 5,205 bpd from the Abo Field in OML 125 and the Ebendo Field.
