Abstract
Summary
Subsalt imaging is a challenging problem and one of the most difficult tasks that the oil and gas industry still faces today. Despite the use of advanced seismic acquisition technologies like wide-azimuth and full-azimuth geometries, processing techniques such as reverse time migration and anisotropic imaging, it is still difficult to use seismic data alone to solve subsalt and presalt imaging problems with great confidence. This work attempts to address subsalt imaging issues in hydrocarbon exploration by demonstrating a methodology of integrating the gravity and seismic data to eliminate or minimize the ambiguity of subsalt interpretation.
