Abstract

Analyses of hydrocarbon-related bright amplitudes in overburden rocks have demonstrated that such amplitude anomalies can often be associated with gas leakage from faults or fault intersections that offset underlying reservoirs. The position of the gas water contact frequently coincides with the depth of the top reservoir surface where it is intersected by the faults. The acoustic expression of the leaked gas differs significantly among areas, and is largely controlled by the caprock lithology.
