Conoil Hits Discovery In Offshore OPL 290

Indigenous oil independent, Conoil Producing, has made hydrocarbon discovery offshore southeast Niger Delta, sparking hopes of more exploration successes despite the lull in the industry. According to regulatory sources, the company which has gained reputation for searching out new reserves in deeper formations encountered over 320 feet of net hydrocarbon sands in about eight levels in Anim-1, in the Oil Prospecting Lease (OPL) 290.

The field is located in the prolific south east shallow water, offshore Niger Delta, and initial logging interpretations confirmed discovery while more logging work is ongoing for Conoil Hits Discovery In Offshore OPL 290 more detailed drilling results. According to industry specific magazine, Africa Oil and Gas Reports, five of those sands are at least 40 feet thick, the rest are between 20 to 25 feet.

The reservoirs are part of the Biafra sands sequence, which is ‘native’ to the south east offshore Niger Delta. “There was an ‘Amenam moment’ in the course of the drilling”, says a DPR source, referring to the French major TOTAL’s discovery of the Amenam field in 1990.

In the same south east offshore neighborhood, TOTAL famously drilled into 3,000 feet of shale in Amenam-1, without encountering a single pocket of sand, emerging, after the ordeal, into an entirely different deltaic sequence, hosting over six hydrocarbon reservoirs between 11,200 feet and 15,700 feet below sea level.

By the time a final investment decision on the field was taken eight years after, TOTAL was proclaiming Amenam as a Billion barrel tank. The drilling experience in Conoil‘s Anim-1 was not so dramatic. In chugging through the massive shale, there were small sand intercalations.

But the DPR sources think that this well may be significant. Anim-1 was spud on June 30, 2015 with the Monarch rig, operated by Depthwize. The well is proposed to reach total depth at 12,500 feet True Vertical Depth, or 13,200 feet Measured Depth.

The well also fulfils the obligations of the Production Service Contract (PSC) on mandatory work programme. Conoil, with production of around 9,000BOPD, has been aggressive on exploration plays in the last three years; and it has had a string of discoveries to show for it, the most widely discussed of which is the Ango field, in Oil Mining Lease (OML) 59, which is now being completed and will soon be tied to existing production facilities in the lease.
