Abstract:

A method for performing a simulation of a field having a subterranean formation is described. The method includes obtaining phase behavior data of subterranean fluids of the field, generating an equation of state (EOS) model of the fluids based on the phase behavior data, generating a Helmholtz free energy model that reproduces predictions of the EOS model over a pre-determined pressure and temperature range, and performing the simulation of the field using the Helmholtz free energy model. The method may further include reducing the EOS model to a reduced EOS model having a reduced number of components to represent the EOS model over a pre-determined pressure and temperature range, generating the Helmholtz free energy model based on the reduced EOS model, and obtaining and using phase behavior data of injection fluids used. A computer system data.

Abstract:

A system and method for showing heterogeneity of a porous sample by evaluating the porous sample to generate a digital core image, performing segmentations on the digital core image using multiple approaches to obtain a segmented volume, dividing the segmented volume into one or more sub-volumes of differing size, calculating one or more petrophysical or fluid flow parameters or porosity from the one or more sub-volumes, and presenting data as a structure composed of grid blocks representing an exact representation of the one or more sub-volumes positioned according to a spatial location of the one or more sub-volumes based on selected parameters or values from the one or more petrophysical or fluid flow parameters or porosity.

Abstract:

Methods of well treatment include modeling approaches that account for the effect of pore structure during well stimulation treatments. In one aspect, methods may include preparing a computer model of a porous medium; simulating an injection of a fluid into the computer model of the porous medium; measuring a pore-scale heterogeneity of the computer model of the porous medium, and designing a stimulating fluid treatment for the porous medium. Other aspects may include the development of a wellbore stimulation methodology that allows stimulation fluid breakthrough curves of differing formation samples to be plotted as a single curve that accounts for the varied pore structure of the respective samples.
