Africa-focused Impact Oil and Gas announced that it raised $12.3m through an underwritten open offer. The company, which has bases in Woking and Cape Town, said it would use the proceeds to pay for subsurface technical work on the firm’s portfolio, including 3D seismic surveys, Energy Voice informed. The open offer was underwritten by Deepkloof, which is a subsidiary of Hoskins Consolidated Investments and Helios Investment Advisers.

The 3D seismic survey will cover approximately 1900km² offshore Namibia, which started in early December, Offshore Engineer reported.

Impact Oil and Gas operates Block 2913B with 85% interest. The block covers 9000km², 300km offshore southern Namibia, immediately adjacent to the South Africa maritime boundary.

Block 2913B is 150km west of the Kudu gas field, but recently Impact stated that exploration wells along the outer fringes of the Orange basin have demonstrated that there is a rich oil prospective zone running through the block. The company has already acquired new 2D seismic data, which identified a number of prospects and leads.
