Sahara Group has discovered commercial hydrocarbons in three onshore oil wells drilled at Oil Prospecting Licence (OPL) 274 in the Edo State block in Nigeria.
The company’s upstream affiliate Enageed Resources has completed drilling the third well, part of a three-well onshore drilling programme, in the block and demobilised HPEB-187drilling rig.
Oluegi-1 was drilled to a total depth of 14,887ft with a horizontal displacement of 2.7km north of the wellhead. It encountered five hydrocarbon zones, totalling 110ft of net pay.
Enageed Resources also drilled two appraisal wells, Oki-Oziengbe South 4 and 5.
Oki-Oziengbe South 4 was drilled directionally to a total depth of 12,520ft 1.1km southwest from the wellhead, logging 211ft of net pay in 13 hydrocarbon bearing zones, of which seven were new.
The well flowed 43° to 44° API oil to surface on two tests at rates of 2,400 barrels a day (bpd) and 3,200 bpd, with no water, on a 0.5in choke.

By GlobalDataOki-Oziengbe South 5 was also drilled directionally, to a total depth of 12,873ft 1km south of the wellhead. It logged 298ft of net pay in 19 reservoirs, 15 of which were oil-bearing and seven new.
The company’s drilling programme followed a two-phase, land-swamp 3D seismic survey in the 871km² license.
Sahara Group upstream COO Curtis Cohen said that the OPL 274 exploration programme realised a number of firsts for the company.
"We shot our first onshore 3D seismic, drilled and operated our first onshore wells, made our first oil discovery and first appraisal, and tested first oil at rates in excess of 5,600 bpd," he said.
"We drilled the three wells back-to-back in just ten months, from a common location and a minimal environmental footprint, and all three wells found commercial hydrocarbons."
