Abstract

Twenty-eight geologically targeted, field development opportunities, including a variety of deeper pool opportunities that could significantly add to Maraven's (affiliate of PDVSA) reserve base, are identified in Lower Eocene Misoa reservoirs in the Stage 2 Area in Block I in north-central Lake Maracaibo, Venezuela with the help of integrated geophysical, geological, petrophysical, and engineering analyses. Seismic rms amplitudes are instrumental in detecting and mapping trends of lithofacies and were integrated into stratigraphic models. Amplitude response to net sand thickness is a linear relationship. The amplitude signature also captures hydrocarbon charge as evidenced by bright amplitudes coincident with structural, fault-bounded culminations. These direct hydrocarbon indicators (DHI) can result from as low as 2% miscible gas fraction within the hydrocarbon column.
