Sub-Salt Studies in the Red Sea

GETECH, the oil services business specialising in the provision of exploration data and geological exploration studies, is pleased to announce a new Advanced Geophysical Services study with Aramco Overseas Company B.V. to map the sub-salt basin structures and depth to basement in a part of the Red Sea. The study will use new methodologies and techniques that have been developed by GETECH to specifically map sub-salt basin areas that are difficult to map with conventional seismic reflection data.

The Advanced Geophysical study results from over two years of developing and testing new 2D and 3D potential field inversion methods. The methods are mainly magnetic and provide clearer images of fault and basement structures using phase and wave number derivatives via our Tilt-Depth and Tilted block methods. The advantage of the phase and wave number methods is that they minimise the effects of rock magnetisation and allow better imaging and clearer understanding of deep basement structures. GETECH is particularly pleased to report this study contract, as it aims to validate our method to accurately map the Red Sea margin. Delivery is anticipated in the third quarter of 2012.

Prof Derek Fairhead, President and Founder of GETECH, commented "Having developed new technology and methodologies, it is very encouraging to be able to apply them to recently acquired high resolution airborne gravity, gravity gradiometer and magnetic data in an area where, because of the salt, conventional seismic is challenged to image the basement structure in a reliable way."
