Reservoir characterization is critical in the assessment of enhanced oil and gas recovery processes. The members of the RC research team focus on characterization of fracture networks and fracture surfaces, permeability estimation for complex carbonate systems, and up-scaling:

Our research in the area of fracture surface characterization includes the experimental identification of fracture surface roughness:

This fills a significant gap in the area of fracture characterization, which is a need in modeling the fluid flow in a single fracture:
