The project goal is to develop innovative seismic-based methodologies and workflows for the incremental recovery of hydrocarbons from karst-modified carbonate reservoirs within the onshore continental United States. The project objectives are: 1) to calibrate new multi-trace seismic attributes for improved imaging of hydrocarbon reservoirs; 2) to develop attribute based, cost-effective workflows to better characterize karst-modified carbonate reservoirs and fracture systems; and 3) to improve accuracy and predictiveness of geomodels and reservoir simulations.
