A form of secondary production, gas injection is used on a well to enhance waning pressure within the formation. Systematically spread throughout the field, gas-injection wells are used to inject gas and effectively sweep the formation for remaining petroleum, boosting production.
Somewhat similar to water injection, or water flooding, gas injection is a pressure maintenance program that can be employed on a reservoir at the start of the production process or introduced after production has already started to lessen. Here, gas is injected into the gas cap of the formation, whereas in water injection, the water is injected directly into the production zone....was just a thought when people were dismissing the gas as of little value
