... because of their high organic material content. This phenomenon is recognized as adsorption, and it is the mechanism by which the gas molecules become attached to the organic materials on the surface of the shale rock. Adsorption is a reversible process, and it impacts the gas production in gas reservoirs...

The time dependence of decane adsorption and desorption in the kerogen isolates was recorded using HF NMR T 2 distributions. The NMR results show potential for predicting hydrocarbon producibility from...

... Abstract Capillary condensation is the condensation of the gas inside nano-pore space at a pressure lower than the bulk dew point pressure as the result of multilayer adsorption due to the high capillary pressure inside the small pore throat of unconventional rocks. The condensation of liquid...

Oil produced from unconventional reservoirs is predominantly light, implying selective hindrance, which may be caused by a combination of size exclusion and preferential adsorption in matrix nano-pores/throats. If so, most of the remaining oil could be heavier than that produced...
