The confined phase behavior was incorporated in the model considering the critical property shifts and capillary pressure. Subsequently, we built a field-scale simulation model of the Eagle Ford shale reservoir. The fluid properties under different pore sizes were evaluated. Finally, a series of studies were conducted to examine the contributions of
Adsorption
Adsorption in shale gas play has an important role as storage gas source since the nanopores inside the kerogen and clay minerals generate and amazing surface area to adsorb gas molecules.
This category shows new researches and papers explaining this phenomenon and their impact in the shale production and reserves estimation.
Shale high pressure isothermal adsorption curve and the production dynamic experiments of gas well
The study results show that the isothermal adsorption law of the shale reservoir under high pressure was different from the conventional low pressure. The high pressure isothermal adsorption curve had the maximum value in excess adsorption with pressure change, and the corresponding pressure was the critical desorption pressure. The high
Molecular simulation of shale gas adsorption in organic-matter nanopore
Unconventional resource’s production under desorption-induced effects
Hence, it is essential to investigate the effects of induced permeability, porosity, and stress by desorption on ultimate hydrocarbon recovery. We have developed a numerical model to study the effect of changes in porosity, permeability and compaction on four major U.S. shale formations considering their Langmuir isotherm desorption behavior. These resources
Isothermal Adsorption and Desorption Properties of Marine Shales on Longmaxi Shale in South China
And adsorption potential theory was used to explain the adsorption and desorption process. According to the results, the shale samples have a high level of organic carbon content with the same organic matter type II1 and high degree of maturation. The volume of adsorption increases rapidly and slows down to
Investigation of methane adsorption on chlorite by grand canonical Monte Carlo simulations
Abstract In this paper, the methane adsorption behaviours in slit-like chlorite nanopores were investigated using the grand canonical Monte Carlo simulation method, and the influences of the pore sizes, temperatures, water, and compositions on methane adsorption on chlorite were discussed. Our investigation revealed that the isosteric heat of adsorption of methane
