A homogeneous model of a gas storage aquifer was designed to investigate the effects of the primary reservoir parameters and gas injection...

We also analyze the effects of gas injection/withdrawal schemes and well perforation schemes on aquifer gas storage performance.

... allows the reservoir liquids to enter the wellbore at a higher flow rate. The injection gas is typically conveyed down the tubing-casing annulus and enters the production train through a gas-lift valves. The gas-lift valve position, operating pressures and gas injection rate are determined to ensure...

... injection stops by using energy in place. The results of a laboratory experiment and corresponding numerical history matching are reported in this paper. The study showed that the hot chamber continued its expansion after steam injection was stopped and a gas injection was initiated. The continuous...

We have seen several cases where standpipe pressures went up rapidly with known reasons in gas drilling. After tripping out of the hole, nothing was found...

Based on the success of this NCG-steam wind-down strategy, a four month flue gas injection test was conducted in 2001 to investigate the possibility of using the more cost effective flue gas than the natural gas as an injectant.
