... wells. Analysis of these data revealed that the early change in liquid yield above saturation point correlated well with changing trend of C1/C2 ratio with time. This would suggest release of C1 from the adsorbed gas as a viable mechanism for the producing CGR alteration. The classical Type I isotherms...

... and isotherms) under varying stress conditions. The objective of this work is to facilitate the interpretation of laboratory-scale experiments, at relevant conditions, in an attempt to bridge the gap in scales between laboratory- and field-scale observations. We have conducted a series of high-pressure...

..., and the isotherms used to model adsorption of CO 2 to shale are listed and their advantages and limitations are described. Another main focus of this research is the capacity of CO 2 that can be stored in shale via adsorption. The research therefore covers the adsorption capacity in scf/ton for different shale...

We then apply our model to three different pore geometries (i.e. slit, circular and triangular) to simulate nitrogen adsorption isotherm at 77 K, which is frequently used for pore size distribution and surface area characterization...

This change was assessed in the context of Langmuir and BET isotherm adsorption models. A 25-year EUR response surface model was created using a semi-analytical model from our previous work. Both OGIP...

This work shows that the non-ionic surfactant is able to reduce the reservoir oil-brine IFT from its original value (27 mN/m) down to 15 mN/m while...
