Marine geophysical company Polarcus completed a 3000sq km 3D sesmic survey in license area EL 0037 in the Walvis basin offshore Namibia for operator Tullow Oil.
A second 2D acquisition phase has now started. It will cover approximately 1000km and will take about two weeks to complete, said Perth-based partner Pancontinental Oil & Gas.
The 3D survey was acquired using seismic vessel Polarcus Asima, and was designed to prove up prospects for drilling. The 3D data will now be processed, with final results expected in about five months.
Fast-track processed 3D data are expected within about 10 weeks, enabling Tullow to commence mapping the prospects, said Pancontinental.
Exploration License 0037 was issued in 2011 and covers 17,295sq km. Tullow Oil farmed-in to EL 0037 in September 2013 and subsequently identified a number of geological leads to check with the 3D survey.
The joint venture participants in Block EL 0010, which adjoins EL 0037, have reported that preparations are underway to begin drilling the Welwitschia-1 exploration well in mid-April 2014. The Welwitschia-1 drilling site is about 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,” said Pancontinental.
The Namibia EL 0037 consortium consists of: Tullow Kudu Ltd. (operator, 65% interest), Pancontinental (30%), and Paragon Oil & Gas (5%).
