Evaluation of Propane-Butane Mixtures as Solvent in ES-SAGD
SAGD (Steam Assisted Gravity Drainage) is a thermal recovery process for production of nearly immobile bitumen from the deeper oil-sand formation. In this method, two parallel horizontal wells are drilled near the reservoir bottom, one about 5 m higher than the other. Steam injected through the …

Experimental Studies on Solvent Screening and Performance Analysis for Bitumen Recovery Using ES-SAGD
… of highly viscous bitumen from oil sands reservoirs requires energy-intensive in-situ thermal methods, notably Steam-Assisted Gravity Drainage (SAGD). While SAGD is commercially proven, it is limited by a high Steam-to-Oil Ratio (SOR) and substantial environmental impact. The Expanding …

Quantification of Phase Behaviour and Physical Properties of Solvents-Heavy Oil/Bitumen-Water Systems at High Pressures and Elevated Temperatures
Due to the excess heat loss of steam assisted gravity drainage (SAGD) processes and low oil production rate of solvent-based processes, the expanding solvent SAGD (ES-SAGD) process has been considered as a promising technique for enhancing heavy oil/bitumen recovery. The main ES-SAGD mechanisms …
