Abstract
An integrated approach to estimate the hydrocarbon resource in carbonate pinnacles uses high end fit-to-purpose seismic velocities constrained by stratigraphic facies mapping as an essential input to pore pressure estimation. The calculated pressure profiles were used for hydrocarbon buoyancy estimation to model the possible column heights, which then assisted in risking, sizing and ranking the exploration prospect portfolio in this overpressured environment.
