Liquid condensate is an important product of gas condensate reservoir, and its recovery should be both efficient and economic. This paper discusses economic development models of all kinds during the last two decades in the engineering field of gas condensate reservoirs, including reinjection with 75% dry gas recycling, dumpflooding of gas, nitrogen injection, water injection, water and gas alternating injection, C〇₂ injection, etc. The results of the study indicate that these development models will be more effective than conventional pressure depletion methods and will be adaptable to complex cases of surface-underground gas condensate reservoirs.
