Experimental Investigation of Salt Precipitation during Gas Injection into a Depleted Gas Reservoir

Abstract: Water vaporization and its induced damage around the wellbore are important issues with a wide application. This phenomenon could be observed wherever dry gas is injected into gas and oil reservoirs in presence of connate water. Gas injection for EOR, pressure maintenance or storage purposes and carbon dioxide sequestrations in aquifers are examples where it could happen. There are two counteracting factors existing in vaporization phenomenon, water saturation decrease and induced permeability impairment by sa… Show more

“…Further, the storage capacity is affected by the distribution of pore and throat in the reservoir and water lock [742]. Moreover, the salt precipitation in the porous medium reduces the injectivity and induces damage [743]. Finally, the retention time affects the storage process because the gas is trapped in water, and only a small fraction can be recovered [744].…”

“…Also other researchers have performed different simulations on natural gas storage process. Golghanddashti et al [10] studied the gas storage in a depleted gas reservoir with edge aquifer at ambient pressure and high flow rates. Also Chun et al investigated the gas storage process at atmospheric pressure.…”
