SWE Announcement: August 26, 2015
Gambella Basin - Full Tensor Gravity (FTG) Acquisition and Analysis Complete
SouthWest Energy, in partnership with ARKeX, has successfully completed acquisition, processing and interpretation of 17,906 km’s of FTG, magnetics and Lidar data in the Gambella basin. The survey proved once again the ability of SWE’s team to manage projects that come in on-time and to budget. Good groundwork and precautions also resulted in blemish free security and health and safety reports over the full length of the 136 day project.
The interpretation of the acquired data is complete and very promising. In total, 156 structures and 48 lead concepts have been identified. The new 3D inversion work reveals morphology of the basement top and other horizons in great detail and sediment thickness reaching 9km is estimated. In an area such as this with a proven and prolific petroleum system and sufficient sediment thickness, a huge opportunity exists for oil to form and migrate upwards to charge the plethora of identified structures.
Image 1 shows the survey grid layout and the high and low grid densities which were designed based on SWE’s assessment of basin’s prospectivity.
Image 2 shows two isolated basins indicated by dashed yellow polygons, and a north western basin (solid yellow polygon) that is closed in the SWE block.
