Advanced Reactive Chemistry Modeling for Reservoir Flow and Transport

The local equilibrium assumption is a well-known simplification to describe instantaneous processes, with widely different time scales when compared to flow time scales. In this proposed work, we employ this assumption for modeling both volumetric and surface processes. This work … Continue reading

An Improved 3D Polymer Model

This research aims to develop a three-dimensional, shear-thinning, non-Newtonian flow model to simulate field scale polymer flooding as a tertiary oil recovery mechanism. The viscosities are calculated based upon direction dependent shear-rates. This provides an accurate representation of the non-Newtonian … Continue reading

BIGDATA: Collaborative Research: IA: F: Fractured Subsurface Characterization Using High Performance Computing & Guided by Big Data (Funded by NSF)

Natural fractures act as major heterogeneity in the subsurface that control flow and transport of subsurface fluids and chemical species. Their importance cannot be underestimated, because their transmissivity may result in undesired migration during geologic sequestration of CO2, they strongly … Continue reading

For fractured reservoirs, the connectivity of fracture distributions is crucial for predicting production characteristics. In this case, since the … Continue reading

Homogenization for Upscaling Reservoir Flow and Transport

Upscaling reservoir properties is pivotal for reducing uncertainty during parameter estimation and history matching. Further the computational cost is also lowered due to a reduced number of degrees of freedom. Upscaling single-phase flow entails estimating coarse scale, effective permeability from … Continue reading

Model selection for reservoir characterization in CO2 sequestration

The ideal reservoir characterization is achieved from a closed-loop system that integrates geological modeling, upscaling/downscaling, reservoir simulation, history matching, and production forecasts associated with unbiased uncertainty quantification. The initial step of reservoir characterization is to identify reservoir models from all … Continue reading
