Objectives of the Project: ? Provide a methodology that allows operators of oil reservoirs in carbonate reefs to better image the interior structure of those reservoirs and to identify those areas which contain the most oil remaining after initial production ? Crosswell seismic resolution of reservoir image is roughly 10 to 100 times higher than surface seismic techniques ? Technique will be used to examine and demonstrate the usefulness of such data for determination of lithology, fluid content, and pressure within producing fields in carbonates
