摘要

Experimental results in the literature indicate that the water solubility in the oleic (L) phase (x(wL)) can be high at reservoir conditions in thermal oil recovery processes. However, the effect of x(wL) on oil recovery has not been fully understood, especially for steam-assisted gravity drainage (SAGD) for in-situ bitumen recovery. This research presents a framework for reliable characterization of water/reservoir oil mixtures for numerical simulation of steam injection processes. The Peng-Robinson equation of state (PR ECG) is used with the van der Waals mixing rules.
