Oil and Gas Exploration in Africa


South Africa, Block 11B/12B

Block 11B/12B is located in the Outeniqua Basin approximately 175 kilometers off the southern coast of South Africa. The block covers an area of 18,734 square kilometers with water depths ranging from 200 meters in the north to 1,800 meters in the south. The Lower Cretaceous Post-rift Paddavissie Fairway, which contains the Brulpadda discovery, is located within the southwest corner of the block.

Total鈥檚 first attempt to drill the Brulpadda Prospect in 2014 was suspended prior to reaching target due to difficulties experienced by the drilling rig in the harsh deepwater environment. After extensive review of the challenging surface conditions, Total contracted the Odfjell Deepsea Stavanger semi-submersible rig to drill the Brulpadda-1AX re-entry well in December 2018.

The Brulpadda well was drilled in approximately 1,400 meters of water by the Odfjell Deepsea Stavanger semi-submersible rig. The well targeted two objectives in a deep marine fan sandstone system within combined stratigraphic/structural closure. Following the success of the main objective, the well was deepened to a final depth of 3,633 meters and was successful in the Brulpadda-deep prospect.

The well encountered oil pay and a total of 57 meters of net gas condensate pay over two Middle to Lower Cretaceous high-quality reservoirs. Core samples were taken in the upper reservoir, and a comprehensive logging and sampling program was performed over both reservoirs..

Four additional prospects have been defined within the fairway. These de-risked prospects have clear amplitude anomalies with excellent structural conformance and flat spots indicating presence of hydrocarbons.

The Paddavissie Turbidite Play covers an area in excess of 2,000 square kilometers and lies at the distal end of a major fan system within the Bredasdorp Basin. These complexes contain stratigraphically and structurally trapped oil and gas within excellent reservoir quality channel sandstones that form feeders to the outboard Paddavissie Fan Systems. Source rocks in the fetch area comprise both mid-Aptian and Hauterivian shales that entered maturity in early Tertiary and are presently within the main stage of oil generation.

Africa Energy holds a 4.9% effective interest in the Exploration Right for Block 11B/12B. The Company owns 49% of the shares in Main Street 1549 Proprietary Limited, which has a 10% participating interest in the block. Total as operator holds a 45% participating interest in Block 11B/12B, while Qatar Petroleum and CNRI hold 25% and 20%, respectively.
