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 approximately 18,734 square kilometers with water depths ranging from 200 meters in the north to 2,000 meters in the south. The Lower Cretaceous Post-rift Paddavissie Fairway, which contains the Brulpadda Prospect, is located within the southwest corner of the block.
Total’s 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-1AX well is being drilled in 1,432 meters of water to a total depth of 3,420 meters below sea level. The well will explore the oil potential in a mid-Cretaceous aged deep marine fan sandstone system within combined stratigraphic/structural closure. The prospect has been de-risked with 2D seismic and electromagnetic surveys. Four additional prospects have been defined within the fairway. In total, the five prospects have multi-billion-barrel resource potential. These 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 is a similar play to the smaller Oryx and Sable oil fields located to the northwest in the adjacent 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.
