Agoco’s Y3-51 Shows Encouraging Results

Sunday, March 31, 2019

AGOCO, a subsidiary of Libya’s NOC, saw promising results from its Y3-51 appraisal well in the Sirte Basin. According to a statement on the NOC website, the well has the potential to flow at rates of 8,500 bpd of oil and 1.82 Mmcf/d of gas.

The well is located north-east of the Nafoura oil field. While the well was drilled in January 2018 to a total depth of 11,300 ft, a thorough testing of the well was not conducted until March 24.

Initial production testing from the Bahi Formation and Upper Cretaceous layer saw the well flowing at a rate of 2,860 bpd of oil and .54 Mmcf/d of gas from the Bahi Formation and 5,635 bpd of oil and 1.28 Mmcf/d of gas from the Upper Cretaceous. The tested interval was between 10,520 – 10,765 ft.

The Y3-51 well was drilled to delineate structure Y to the north-west of discovery well Y1-51, drilled in 2000, with promising test results of 3,892 bpd. This was followed by the Y2-51 in 2003, however the results were not encouraging. AGOCO is currently drilling appraisal well Y4-51.

NOC and AGOCO are working on developing these fields and increasing production. Full exploration of structure Y is a strategic priority, as it is expected to add 38 million bpd of oil, and 12 Bcf of gas, with recoverable reserves of 11 million barrels of oil, and 10 Bcf of gas.
