The 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, in the North-Eastern part of Nigeria.

Drilling of the Kolmani River II Well was flagged-off in a ceremony by President Muhammadu Buhari on the 2nd of February, 2019.

The NNPC in a statement Friday in Abuja said it acquired 435.54km2 of 3D Seismic Data over Kolmani Prospect in the Upper Benue Trough, Gongola Basin. This was to evaluate Shell Nigeria Exploration and Production Company (SNEPCo) Kolmani River 1 Well Discovery of 33 BCF and explore deeper levels it said.

The well was drilled with “IKENGA RIG 101” to a total depth of 13,701feet encountering oil and gas in several levels. A Drill Stem Test (DST) is currently on-going to confirm the commercial viability and flow of the Kolmani River reservoirs.

The Corporation explained that on Thursday 10th October, 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.

Preliminary reports indicate that the discovery consists of 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.

Computation of hydrocarbon volume is on-going and will be announced in due course, the corporation said.

The NNPC added that it has also acquired additional 1183kmof 3D seismic data over highly prospective areas of Gongola Basin with a view to evaluating the full hydrocarbon potential of the Basin.

“NNPC deployed world class cutting-edge technologies including Surface Geochemistry, Ground Gravity/Magnetic, Stress Field Detection, Full Tensor Gradiometry aerial surveys to de-risk exploration in the frontier basins. The NNPC plans to drill additional wells for full evaluation of the hydrocarbon volume in the Gongola Basin,” the statement said.

President Muhammadu Buhari had during the spud-in ceremony of Kolmani River II, stated the commitment of his administration to the exploration for oil and gas in the frontier basins in the entire length and breadth of the country. The basins include: the Benue Trough, Chad Basin, Sokoto and Bida Basins.

He also stated that attention would be given to the Dahomey and Anambra Basins which have already witnessed oil and gas discoveries.
