Spectrum, in collaboration with the Direction Generale des Hydrocarbures (DGH), has completed the first phase of its 3D Multi-Client seismic acquisition program offshore Gabon.

The 11,400 km2 Gabon South 3D survey which collected data at water depths of 28-850 m over the Gryphon blocks, was successfully accomplished at the end of July ahead of schedule and without incident. Gravity and magnetic data was also acquired in conjunction with the seismic data. The survey now offers the most up-to-date 3D imaging of an area which covers a number of under-explored shallow water open blocks on trend with existing production in Gabon and major new discoveries in the Congo. It will significantly accelerate evaluation of the area for future License Rounds, facilitating immediate activity when the blocks are awarded.

Spectrum plans to continue this shallow water program through the acquisition of a 5,500 km2 3D survey over open acreage in Northern Gabon.

In addition to this new 3D seismic, Spectrum holds over 20,000 km of 2D seismic data offshore Gabon. This data gives a regional overview and highlights key areas of exploration. Spectrum also offers gravity gradiometry data and basin modelling information relating to southern offshore areas.

The optimum design and acquisition parameters for the Gabon South 3D survey were selected following an extensive review of these vintage 3D surveys over the open blocks which resulted in the best possible image of the pre-salt section without compromising the post-salt imaging.

Fast track products are expected to be available toward the end of 2017 ahead of anticipated future Licensing Rounds.
