Systems and Methods for Modeling Subterranean Formations that Include Gaseous Hydrocarbons and Adsorbed Hydrocarbons

摘要

Systems and methods for modeling subterranean formations that include both gaseous hydrocarbons and adsorbed hydrocarbons. The systems and methods include determining a formation volume factor for gaseous hydrocarbons that may be present within the subterranean formation and correcting the formation volume factor to generate a compensated formation volume factor. The systems and methods further may include simulating a fluid flow within the subterranean formation, with the simulating being based, at least in part, on the compensated formation volume factor. Correcting the formation volume factor may include adjusting the formation volume factor based, at least in part, on a fraction of the adsorbed hydrocarbons within the subterranean formation that desorbs from the subterranean formation and/or transitions to gaseous hydrocarbons during production of the gaseous hydrocarbons from the subterranean formation.
