... of that of scenario 1, and the duration of the injection in scenario 3 is increased compared to scenario 1. The rate and duration of injection are adjusted to ensure a similar volume of stored gas in each simulation run. The outcomes show that fast injection prevents significant compaction in the reservoir. Besides...

... closure characteristics was observed. It was found that injectivity was controlled by the interplay of fines transport away from the injection region, resulting in injectivity increase, and the permanent compaction of the sand around the cavity, resulting in injectivity decrease. The first-time insights...
