Following discovery of the oil field on 2D seismic data in 2010, Central acquired 3D seismic data in 2012 to better define the structure. The 3D seismic survey was able to more accurately map the Surprise structure. It also showed that a previously mapped fault fully splits the structure in two. The undrilled eastern culmination is referred to as Surprise East. In 2020, a study will be undertaken to evaluate options for further development of Surprise and the appraisal of Surprise East.
Mamlambo 1 is 8km from the Surprise Field and will be drilled as a part of the CY2020 exploration programme. Any success in the well could provide significant cost-saving synergies in a combined development programme.
