Article Title: Gravity Support for Hydrocarbon Exploration at the Prospect Level
by B. S. Badmus, N. K. Sotona and Krieger, M

Abstract:
Exploration sites with complex geophysical structures like salt bodies, significant to hydrocarbon exploration are difficult in seismic interpretation to delineate. An integrated approach using land gravity information with integrated seismic horizons in building a model for these complex structures via a 3-D gravity forward modelling was used. The acquired Bouguer gravity data was filtered using low, high and band pass filter, removing regional trends and high frequency anomalies. First horizontal derivatives and second vertical derivative maps were obtained from the Bouguer gravity, revealing the pattern of faulting and enhance near-surface features. A 3-D body was created and modelled with seismic horizons as constraint until the calculated gravity effects of the model match the observed gravity or are deemed close enough
Keywords: bouguer gravity, salt domes, hydrocarbon traps, contour maps and seismic horizons
