This paper describes an integrated study of utilizing 3D seismic, open hole logs with simulation, pressure transient analysis and production data to define and map fracture network patterns to aid enhance the productivity from thick, tight and fractured deep gas-bearing carbonate reservoir in the Bahrain field. The Lower Permian K3 zone is a thick, tight, highly faulted and irregularly fractured Carbonate reservoir. The massive 800 ft thick reservoir with very low average permeability of the order of 1 md, poses challenge in efficient recovery of hydrocarbons. The present production from this thick reservoir accounts for less than 10 % of the total gas production from the Khuff Formation of the field. This has prompted a detailed integrated study to help enhance the well productivity. It is well known that seismic coherence data plays a pivotal role in defining and mapping fracture network and similarly well testing to understand the reservoir dynamics and connectivity. The approach involves identification of fracture network from seismic data and validating them with transient well testing & production data at and around well-bore. The study is applied to derive and input fracture network and related data of the K3 zone into the simulation model to define and map the reservoir fracture patterns to aid in increasing productivity and also recovery.
