Thelma Project (80 square kilometers)
The Thelma Project is a shallow oil prospect located on the well documented Ruston-Sevango dome in the Danhauser area on the northeast edge of the northern Karroo Basin of South Africa. The prospect covers about 2.6 Km2 of the 80km2 project area. The dome is a draping of Ecca age sediments over a paleo-relief high and has a well defined closure of about 30 meters.

Previous engineering evaluations indicate recoverable reserves of 1.7 to 6 million barrels of oil. Government geologic reports suggest that the structure could be at least twice as large, thereby containing more than 25 million barrels of oil in place with correspondingly higher recoverable reserves. The primary objectives of this project are the Mid-Lower Ecca Sandstones found at depths of 90 to 180 meters. The project is easily accessible and is located within a few miles of an oil pipeline that runs directly to an oil refinery. This refinery is dependent on imported crude and it is currently operating at less than full capacity.
