Extensive 3D seismic survey progressing offshore Namibia

11th April 2014

A Tullow Oil-led joint venture has announced that an extensive 3D seismic survey has been completed within its highly prospective offshore acreage in licence area EL 0037 offshore Namibia, southwest Africa.

Drilling results from elsewhere in the Walvis Basin have proved encouraging for the presence of mature source rocks, and regional wells show good evidence of reservoir quality sands in the Cretaceous interval.

A Tullow Oil-led joint venture has announced that an extensive 3D seismic survey has been completed within its highly prospective offshore acreage in licence area EL 0037 offshore Namibia, southwest Africa.

Australian firm, Pancontinental Oil and Gas (a 30 per cent stake holder in the venture), has reported that the 3D acquisition, over approximately of 3,000 square kilometres, covers a number of strong ‘leads’ that have already been mapped on existing 2D seismic data. A second 2D acquisition phase will cover approximately 1,000 km. The survey is designed to prove a number of prospects for drilling.

EL 0037 covers an area of 17,295 square kilometres in the Walvis Basin. Offshore Namibia is considered highly prospective for oil and gas, lying south of the prolific producing areas offshore Angola, with which it shares some geological characteristics. High quality oil-prone source rocks have been seen in regional wells, and two of these source rocks have been reported to be oil mature and considered to be generating oil in the Wingat-1 well in an area immediately south and geologically on-trend to EL 0037.

Joint venture participants in neighbouring Block EL 0010 have reported that preparations are being made to commence drilling the Welwitschia-1 exploration well in mid-April 2014. The Welwitschia-1 drilling site is approximately 75km from the north-east boundary of EL 0037. Drilling results from elsewhere in the Walvis Basin have proved encouraging for the presence of mature source rocks, and regional wells show good evidence of reservoir quality sands in the Cretaceous interval.
