A 3D seismic campaign is being launched on the Dussafu Marin offshore Gabon. The survey is being carried out by Polarcus and covers approximately 1,260 sq km in the outboard part of the license according to Panoro Energy.
The primary objective is to upgrade leads that have previously been identified on 2D seismic data to be drillable prospects. These leads, which are expected to contain pre-salt Gamba and Dentale sandstones, have recently become more attractive following the identification of the high-quality oil bearing Dentale reservoirs in the Tortue discovery.
The 3D data set is expected to provide a better understanding of the size and risking of the prospects prior to any future exploration drilling decision in this area. The survey will also cover the Ruche and Tortue discoveries made in 2011 and 2013 respectively. The seismic survey will also cover re-shooting a portion of the existing 3D seismic originally acquired in 1994.
A subset of the 1994 3D seismic survey is currently being reprocessed over the discoveries to better define the discovered volumes, the new 3D survey is expected to provide data of significantly higher quality. The new seismic data should allow for better placement of future development wells once a field development decision is taken for the Ruche and Tortue discoveries.
The new 3D seismic acquisition program is expected to be completed by mid-November 2013, with the first high quality seismic products available during Q2 2014. The fully processed seismic data is expected to be available for interpretation and mapping in the second half of 2014.
