Effect of CO2 Content on the Natural Gas Production from Tight Gas Sandstone Reservoirs [PDF]
SPE Middle East Oil & Gas Show and Conference, 2017 Abstract The simulation of the gas flow in tight sandstone reservoir is a very complicated process. Several mechanisms contributed to the natural gas production in tight sandstone reservoirs. One of the main mechanisms is the gas desorption from the rock surface to the pore body. All the existing models did not consider the effect of CO2
