Nigerian National Petroleum Corporation (NNPC) has announced the discovery of hydrocarbon deposits in the Kolmani River II Well on the Upper Benue Trough, Gongola Basin, North-East Nigeria.

Concise News reports that this was achieved eight months after President Muhammadu Buhari inaugurated drilling of the Kolmani River II Well.

Spokesman for the corporation, Samson Makoji, said on Friday that NNPC acquired 435.54km2 of 3D Seismic Data over Kolmani Prospect in the area.

It was learned that the well was drilled with “IKENGA RIG 101” to a total depth of 13,701feet encountering oil and gas in several levels.

According to the NNPC, a Drill Stem Test is ongoing to confirm the commercial viability and flow of the Kolmani River reservoirs.

The corporation, in a statement, stated that on Thursday, October 10, 2019, at 18:02hours, one of the reservoirs was perforated and hydrocarbon started flowing to the well head at 21:20hours in which the gas component was flared to prevent air charge around the Rig.

The discovery, according to preliminary report, consists gas, condensate and light sweet oil of API gravity ranging from 38 to 41, found in stacked siliciclastic cretaceous reservoirs of Yolde, Bima Sandstone and Pre-Bima formations.

The corporation said it had also acquired additional 1183km2 of 3D seismic data over highly prospective areas of Gongola Basin with a view to evaluating the full hydrocarbon potential of the Basin.

NNPC stated that it deployed Surface Geochemistry, Ground Gravity/Magnetic, Stress Field Detection, Full Tensor Gradiometry aerial surveys to de-risk exploration in the frontier basins.

It said it plans to drill additional wells for full evaluation of the hydrocarbon volume in the Gongola Basin.
