Compositional reservoir models have many uses, including petroleum reservoir simulation,
the simulation of flow and remediation of nonaqueous petroleum liquids, and the study of …

The formation of three phases with CO2/oil mixtures at temperatures below about 120° F is
well established. Several West Texas crude oils form three phases at CO2 concentrations …

Miscible gas flooding is a common method for enhanced oil recovery. Reliable design of
miscible gas flooding requires compositional reservoir simulation that can accurately predict …

Compositional simulation of solvent injection requires reliable characterization of reservoir
fluids by use of an equation of state (EOS). Under the uncertainty associated with …

Equations of state (EOSs) are typically tuned to black-oil pressure/volume/temperature (PVT)
data such as constant volume-depletion, constant-composition-expansion, differential …

An equation-of-state (EOS) fluid characterization has been developed to model three-
hydrocarbon-phase equilibria as part of the enriched-gas EOR research program for the …

This paper describes an instrument to measure the interfacial tension (IFT) of aqueous
surfactant solutions and crude oil. The method involves injection of a drop of fluid (such as …

Reliable design of gas and/or steam injection for enhanced oil recovery requires
compositional reservoir simulation, in which phase behavior of reservoir fluids is …

Petroleum fluids can in the presence of CO2 present a complex phase behavior. Both two-
phase (VLE and LLE) and three-phase regions (VLLE) might occur within certain ranges of …
