Afren and its partner Oriental Energy Resources have announced the completion of the Ebok-5 appraisal well.


  • The Ebok- 5 appraisal well has been drilled to a total depth of 3,743' md
  • Ebok-5 has encountered a further 54 ft of gross oil pay in the D2 and LD1F reservoirs
  • The oil column is full to base in both reservoirs
  • Extensive log and pressure data has been acquired over these intervals, which are currently being analysed
  • A total of four oil-bearing reservoirs were encountered ranging in measured depth from 2,341 ft. to 3,090 ft.

The Ebok-5 well, which was drilled by Transocean's GSF Adriatic IX jackup drilling unit, has been drilled to a total depth of 3,743'. The well encountered a total gross oil column of 266 ft in the D1 and LD-1E reservoir sands ranging in measured depth from 2,341 ft to 3,090 ft, in addition to a further 54 ft of gross oil pay in the D2 and LD1F reservoirs.

Analysis of an extensive logging and sampling program on the D1, LD1E, D2 and LD1F sands is ongoing.

Osman Shahenshah, Chief Executive of Afren, commented, "The Ebok-5 well results have exceeded pre-drill estimates, and provide an important additional calibration point for the amplitude model, which will assist in further appraisal and de-risking of the remaining upside potential in the Ebok - Okwok complex."

Alhaji Mohammed Indimi, Chairman of Oriental, commented, "We are delighted with the successful results of the Ebok-5 appraisal well. Since Afren and Oriental established our partnership, we have grown the resources base on Ebok from a pre drill minimum economic field size of circa 25 million barrels to a current recoverable reserves base in excess of 78 million barrels. We look forward to further increasing our presence in the Ebok-Okwok area."
