3D seismic data is being acquired over an area of 300 km2 including the CS-10/10A and CS-11 wells. The data will be used to refine the structural closure to allow detailed reservoir interpretation and to identify additional potential areas. The survey started in the second half of 2013 and is expected to be completed, processed and interpreted in the coming months. A new well based on the results of the 3D survey is planned to be drilled later in 2014.
