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 method and system for analysis of a digital core image obtained from a sample are disclosed. The method includes performing segmentations on the digital core image using multiple approaches to obtain multiple segmented images which are statistically analyzed to select the most suitable approach of the multiple approaches. Thereafter, a digital core model is generated using the segmented image corresponding to the most suitable approach. A simulation test may be performed on the digital core model to obtain a model test result and an oilfield operation may be performed based on the model test result. The system includes measurement and testing equipment to obtain the digital core image and a computing system including a data repository for storing a digital core image and a digital core model, and a digital core modeling tool. The digital core modeling tool performs the segmentations, statistical analysis, and generates the digital core model.

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.
