5,445 km of MC2D seismic data acquired offshore Ghana as a part of WEASPAN™ project, in partnership with ION. PSTM data available Q3 2018. Ghana’s first licensing round will launch Q4 2018.
The survey objective is to image the basin architecture, define the limits of the various basins along the equatorial margin and identify petroleum systems offshore West Africa. It integrates available offshore well data to calibrate key stratigraphic horizons regionally and place this part of the margin in a larger (continental) context.
The uniform acquisition and processing of the new data provides a valuable calibration for AVO, phase rotation & amplitude balancing of existing datasets and for application of future technologies.
