Abstract

Gandhar field of Ankleshwar Asset is consisting of multilayered sandstone reservoir of Eocene age. The field is producing from fourteen different sand units of highly heterogeneous in nature. Presently the field is in tertiary recovery stage of production and IOR / EOR scheme is under implementation. Efforts are on from asset team to improve the recovery factor from its current average value of 39. But severe heterogeneity and complexities in the reservoir properties are the main hindrance to achieve this goal. Sometimes it is difficult to plan a proper exploitation strategy to increase the Producibility for some of the sand units
