Abstract

Multi-layered limestone reservoirs of Mumbai High field are heterogeneous in nature. This field is under oil production for more than three decades now and presently under active water-injection. Reservoir complexity and heterogeneity adds additional challenge for proper understanding of these reservoirs. To sustain oil production and reducing water-cut, formation evaluation behind casing is a powerful tool to determine the present day reservoir scenario. Present paper includes two case studies of two development wells from the same platform using analysis behind casing. Based on the data of cased hole logs, work- over jobs were carried out in these wells which resulted in increase in oil production.
