Pore-Scale Modelling of Solvent-Based Recovery Processes

A Pore Scale Evaluation of Produced Biosurfactants for Ex-situ Enhanced Oil Recovery

Microbial enhanced oil recovery (MEOR) is an economical method used to improve the oil recovery from reservoirs. In the MEOR techniques, by applying different microorganisms, a variety of products such as bioacid, biogas, biosurfactant, and biopolymer are generated, among which biosurfactant, one of the important metabolites, is produced by bacteria. It is worthy to note that bacteria are suita...

Pore-scale modeling: Effects of wettability on waterflood oil recovery

Scale-up Strategies for Membrane-Based Desalination Processes: A Review

Membrane-based technologies have increasingly been chosen in desalination processes, which is evidenced by the increase of large-scale plants constructed in recent years. Indeed, several appropriate strategies should be considered to minimize problems faced during the construction, such as membrane system designs, area requirement, energy requirement, operation and maintenance, and environmenta...

Imperial College Consortium on Pore - Scale Modelling Second Progress Report

We describe the early stages of a poreto coreto reservoir-scale investigation of wettability variation and its impact on flow during oil recovery. We use a threedimensional pore-scale network representation of a Berea sandstone to predict relative permeability and capillary pressure hysteresis. We successfully match experimental data for the water-wet case, and then focus upon the effect of var...

Pore Scale Processes Associated with Subsurface CO2 Injection and Sequestration

The injection of CO2 into the Earth’s subsurface drives the fluid-rock system into “farfrom-equilibrium” conditions, which means that the fluxes that return the system to equilibrium are nonlinearly related to the generalized driving forces (e.g., chemical affinities and gradients in the fluid pressures and chemical potentials). The nonlinear response results in emergent structures and self-org...
