Carbonate reservoirs account for more than 50% of total known reserves in the world. Identifying this important reservoir rock and its porosity from seismic data is an essential task in exploring and exploiting carbonate reservoirs for the oil and gas industry. We demonstrate a data driven approach that utilizes bandwidth extension to increase resolution and aid in mitigating NMO stretch, followed by three-term AVA inversion and petro-elastic evaluation for rock properties conversion.

A case study is performed in the Middle Cretaceous aged Edwards reef of South Texas and the successful results confirmed by wells are presented.
