Abstract: An equation state with a mixing rule that captures a multi-component layering within nanopores may be used to model (1) fluid mixture in the nanopores of the reservoir and (2) movement of fluid between the nanopores and large pores of the reservoir. Such modeling of fluid behavior in large pores and nanopores of the reservoir may enable more accurate simulation of the reservoir (e.g., for hydrocarbon recovery).

Abstract: A method of improving a field operation that comprises a gas injection may include assessing a plurality of potential injection gases against a plurality of values of a plurality of parameters associated with a plurality of samples, where each of the plurality of potential injection gases comprises an acidic component, and where the plurality of parameters comprises fluid chemistry parameters and rock properties. The method may also include determining a proposed injection gas from among the plurality of potential injection gases for the field operation that comprises the gas injection to be performed using a first wellbore in fluidic communication with a first subterranean formation, a second wellbore in fluidic communication with the first subterranean formation, a third wellbore in fluidic communication with a second subterranean formation, or any combination thereof.
