Namibia Update and statement regarding the Graff-1 exploration well
Tower Resources plc (the "Company" or "Tower" (TRP.L, TRP LN), the AIM-listed oil and gas company with a focus on Africa, is pleased to provide an update on activity in respect of license PEL 96 in Namibia, covering blocks 1910A, 1911 and 1912B (the "Namibian Blocks") and in particular the recent news regarding the Shell-operated Graff-1 exploration well.
Tower has noted the announcements by the National Petroleum Corporation of Namibia ("Namcor"), and also operator Shell Namibia Upstream B.V. ("Shell"), and partner QatarEnergy, confirming that the Graff-1 well on PEL 39 has made a discovery in both its primary and secondary targets, and proved a working petroleum system for light oil in the Orange Basin, offshore Namibia. The partners' announcements say that they intend to perform further laboratory work and also intend to drill a second exploration well, to determine the size and recoverable potential of the discovery. The Graff-1 well was drilled, apparently without incident and in around 50 days, to a total depth of 5,376 metres in water depths of approximately 2,000 metres.
Other press reports have indicated that the well has been drilled in a slope channel system with a startigraphic trap, and has encountered at least one 60-metre layer of hydrocarbons, holding an estimated 250-300 million barrels of light oil, in an Upper Cretaceous sandstone reservoir. While the announcements say nothing about the source rock, it appears reasonable to infer that the light oil has been generated in Lower Cretaceous (probably Aptian-Barremian) or possibly older/deeper source rocks.
Tower's net acreage position of 18,637 km2 is believed to be the third largest net acreage position in the Namibian offshore, after Exxon and Eco Atlantic Oil & Gas.
Tower's Namibian Blocks, covering a gross area of 23,297 km2, are in the Northern area of Namibia's offshore, in the Walvis basin which is closer to the border with Angola and the Namibe basin, approximately 950 kms away from Graff-1. While this is a considerable distance, certain conclusions can nevertheless be drawn that are relevant to our Namibian Blocks.
1. Initial conclusions
The most important point is that the Graff-1 well demonstrates conclusively the potential for source rocks in the Namibian offshore to have been buried sufficiently to generate light oil in substantial quantities. In the past, this had been open to question, as the only potentially commercial reservoir previously encountered in the Namibian offshore had been the Kudu gas discovery, and the Lower Cretaceous source rock at Wingat-1 (about 250 kilometres to the South of our Namibian Blocks) had produced light oil but until now no substantial oil-charged reservoir was found. The result at Graff-1 therefore reduces the
