The Ravva Field is located in the KG Basin, Eastern offshore India. The field was discovered in 1987 and has been on production for more than 20 years from Middle Miocene reservoirs and has recovered substantial amount of hydrocarbon till date. The Middle Miocene reservoirs have been deposited in shallow marine conditions and are thought to be shoreface and distributary channels in an overall wave dominated setting. Seismic-based reservoir characterization at flow unit levels, facies mapping, detailed rock and fluid characterization and identification of optimal completion technologies have helped to determine effective reservoir management strategy to maximize hydrocarbon recovery.
