... Abstract The density distribution of hydrocarbon molecules in Nano-pore media affects the storage of gas, particular for shale reservoir which contains rich organic matters. The density distribution can reveal the adsorption effect which is related to the gas storage mechanism. In literature...

... fracture closure stress. The measurements also revealed that gas adsorption, when an adsorbent gas was used for the mesurements, resulted in a reduction in the absolute permeability of the sample. Reservoir Characterization flow in porous media Upstream Oil & Gas adsorption net stress...

..., the measurement results with adsorbent gases indicated that the adsorbed gas layer thickness can significantly impact the gas transport and storage in organic rich shale reservoirs and needs to be considered for hydrocarbon in place calculation and production predictions. complex reservoir adsorption...

... of using strain gauges. An improved mixed gas adsorption isotherm model based on the extended-Langmuir theory has been shown to correctly model mixed gas sorption-induced strain based on pure gas strain data and a parameter accounting for gas-gas interactions that is independent of the coal substrate...

... not contain mercaptans or other odorants. However, there are instances when odorized gas from city distribution systems has been injected into underground gas storage fields. Mercaptan solubility in ground water and high adsorption to rock surfaces must be considered to prevent potential underground water...

... Although preliminary research has illustrated the effectiveness of gas injection, complete adsorption data on the pure gases methane, nitrogen and carbon dioxide and their mixtures is necessary before any meaningful, comprehensive understanding can be reached regarding the adsorption/desorption...

... from a producing gas well, while the oil used was taken from a gas well in West Virginia that is producing from the shale interval. Helium and methane isotherms were collected up to 1000 psia for analysis of the adsorptive properties of these substances. It is shown that about 50% of the gas...

... of such material is sufficient, the oil-water-matrix contact angle can be significantly greater than zero. The effect of increasing temperature in such a system will usually be to shift the adsorption equilibrium causing desorption of surface active material and a decrease in contact angle. A simple geometrical...
