Experimental Studies on Solvent Screening and Performance Analysis for Bitumen Recovery Using ES-SAGD
… 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 Solvent Steam Assisted Gravity Drainage (ES-SAGD) process is a hybrid …

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 …
