.... Previously we showed using a combination of experimental methods and molecular simulation studies that kerogen type, thermal maturity, and reservoir temperature conditions affect the contact angle of the water droplet on kerogen surface, and therefore, wettability of kerogen. Wettability affects...

... Abstract Understanding why injected water flowback rates are so low is of primary interest from operating and environmental standpoints. In this work, matrix and fracture flow mechanisms are explored using a new fully-coupled fluid flow and geomechanics simulator. Specifically, we look...

Hydrocarbon properties from pressure-volume-temperature laboratory analysis (PVT) and well production data allowed separation of hydrocarbon types into several different oil and gas-condensate categories. Gaussian simulation is used to generate most of the property models. Hydrocarbon...

The incorporation of shear stress into the simulation generates DSS/DAS time histories that entail complexities beyond what is observed in cases where tensile stress is the unique failure mechanism...

... Splines, respectively. The 3D geomodeling was reconstructed using the variogram-based algorithms of Sequential Indicator Simulation (SIS) for lithofacies/electrofacies and Sequential Gaussian Simulation (SGS) for permeability and porosity. Even though the reservoir has a complex structure, the SIS...

Abstract Understanding the adsorption characteristics of kerogen with respect to reservoir fluids can have significant impacts on distribution of fluids in organic-rich mudrocks and consequently on electrical and mechanical properties. Recent experimental and molecular dynamics (MD) simulation...

In this paper, we present a modeling study of the problem using an advanced simulator "GeoFrac-3D" that can consider irregular fracture geometries and non-orthogonal intersection between the HF and NF, thereby capturing realistic flow and proppant...

... evidence of crowding effect on diffusion in nanoporous shale reservoirs. Effect of crowding is recognized by the reduction of diffusivity and deviations of diffusion characteristics from those of classical (normal) diffusion under confinement. We used molecular dynamics simulations at 239°F to investigate...

Spontaneous-imbibition simulations indicate that the low salinity fluids promote a change in water-oil capillary pressure, leading to increased water uptake in the cores...
