Abstract: A coreflood experiment may be modeled by generating a three dimensional computer simulation model of a core plug and modeling within the three dimensional computer simulation model one or both of a fluid introduction element or a fluid extraction element of a core holder used in the coreflood experiment. Once generated, the model may be loaded and used when running a simulation to model a heterogeneous distribution of fluid flow proximate one or more faces of the core plug.

Abstract: A method, apparatus, and program product model an Enhanced Oil Recovery (EOR) process in a subsurface volume by computer modeling a variable-concentration injection of an EOR agent in multiple grid blocks of a reservoir grid, where the variable-concentration injection includes an injection of the EOR agent at multiple injection concentrations. For a first grid block among the multiple grid blocks within which EOR agent is present, a viscous fingering effect is modeled by modifying a fluid mobility in the first grid block based at least in part upon the injection concentration of the EOR agent present in the first grid block.

Abstract: A well stimulation modeling method and simulation model for modeling a stimulation treatment involving a chemical reaction between a treatment fluid and a porous medium, such as acid treatment of a carbonate formation. In a wormhole initiation stage or mode, the medium of the cells having a solid saturation above a respective critical solid saturation is comprised of matrix material behaving as a single permeability, single porosity system; and in a wormhole growth stage or mode, the cells having a solid saturation equal to or less than the respective critical sold saturation comprise two different interconnected media, the matrix material and a wormhole material, defined to include wormhole-forming material as well as mature wormholes, having fluid mobility as a function of the solid saturation.

Abstract: A method, apparatus, and program product may generate and/or utilize a three-dimensional computer simulation model of a core plug suitable for use in a computer-implemented general purpose reservoir simulator. Simulation studies may be performed on the simulation model to establish a water base case for the simulation model, and to establish one or more Enhanced Oil Recovery (EOR) chemical properties and further validate the simulation model.

Abstract: An apparent viscosity of an aqueous polymer composition used in a polymer flood may be determined by generating a relative permeability interpolation computer simulation model that is associated with a capillary desaturation function and that interpolates relative permeability curves for a coreflood experiment, validating the relative permeability interpolation computer simulation model using experimental data generated from the coreflood experiment using a water flood performed at a plurality of incremental flow rates on a core plug, determining an interpolated relative permeability to water for the aqueous polymer composition using experimental data generated from the coreflood experiment using a multi-phase flood with the aqueous polymer composition, and determining an apparent viscosity of the aqueous polymer composition from the interpolated relative permeability to water. The determined apparent viscosity may then be used to run a simulation to model the flow of the aqueous polymer composition.
