Erin Energy Corporation on Wednesday announced that it has completed the drilling of the Nigeria’s Oyo-NW well, and based on the preliminary evaluation, discovered hydrocarbons in the Miocene Formation.
The well is located approximately 9.5 kilometers northwest of the Oyo Central field on the Company’s offshore Nigeria block 120, according to the company’s statement on the website, seen by Businessamlive.
The Miocene formation is where several of Erin Energy’s neighbours have discovered billions of barrels of hydrocarbons and from which several hundred thousand barrels per day are produced offshore Nigeria.
The Company is currently completing well-suspension activities so it can re-enter the well in the future for possible production.

Femi Ayoade, the company’s chief executive officer said, according to the press release, that “these results are very encouraging and support our technical team’s evaluation of the prospectivity of the Miocene and have significantly de-risked the other major Miocene prospects in blocks 120 and 121.”
“We will move quickly to appraise the discovery. The Miocene is the most prolific producing zone offshore Nigeria, and the presence of these hydrocarbons is a significant step forward in unleashing the value of the Miocene Formation in our blocks,” Femi said.
The well was successfully drilled to the proposed total vertical depth subsea (TVDSS) of 12,218 feet and penetrated multiple sand units with a total gross thickness of 260 feet in the depth range from 7,052 – 10,873 feet TVDSS as interpreted from wireline log data.
Preliminary evaluation of the well data shows that the two main sand units, the Miocene U7.0 and U8.0, with a gross thickness of approximately 83.6 feet are hydrocarbon-bearing. Work has commenced to estimate the discovered volumes and to determine the relevant appraisal and development program.
