Diffusion and dispersion play significant roles in miscible displacements. In the present study, the frontal instabilities in miscible displacements incorporating both concentration-dependent diffusion coefficient (CDDC) and velocity-induced dispersi

The nonlinear dynamics of miscible flow displacements in homogeneous porous media are examined for the special case of concentration-dependent diffusion coefficient (CDDC) models. Highly accurate numerical methods are used to simulate the time evolut

Mass transfer plays an important role in influencing the efficiency of miscible displacements in solvent-based processes in enhanced oil recovery. The mass transfer rate because of the pure molecular diffusion is very slow. However, this process can

The wettability of tight reservoir rock plays a critical role in affecting relative permeability and in turn oil recovery. However, the link between wettability and its effects on oil recovery remains poorly understood, and the potential to boost oil

The frontal instabilities are a key control factor which can significantly affect the sweep efficiency and oil recovery in miscible flooding processes. Under unfavorable viscosity ratio between injection solvent and oil, the frontal instabilities are

For waterflooding in argillaceous reservoirs, the injection water needs to be carefully designed to avoid formation damage by clay swelling and migration. Common methods of achieving this are compatibility tests of injection water with formation wate

This research sought to determine whether surfactants and other steam additives can further improve oil recoveries in steam-assisted gravity drainage (SAGD), and to identify plausible mechanisms. It involved extensive experimental study and method de

Laboratory evaluation of tight oil production processes requires a unique coreflood apparatus that portrays both the tight rock matrix and fractures—a dual-permeability system. However, with some tight formations such as the Bakken having no availa

Solvent vapor extraction (SVX) process has been proposed as an approach to improve heavy oil production after cold production. The wormholes formed during cold production can be utilized as conduits available to produce diluted oil in SVX process. Th
