An Attempt to Revitalize Watered-Out Gas Condensate Fractured Reservoir by Gas Injection

This work challenges to the redevelopment of a mature gas condensate fractured reservoir with strong aquifer. Typically, fractured basement reservoirs have the inherent disadvantages; rapid decline rate, limited reserves, early water coning, and so on. Flow simulation model is built by an actual field data to evaluate lean gas injection even in watered-out gas condensate reservoirs. We verified the potentiality of gas injection method as EOR/EGR techniques in simulation case studies. The result of simulation study indicates that considerable amount of condensate can be recovered and the native gas can be recovered durng gas injection and reproduction.
