A new pressure control scheme on steam-assisted gravity drainage for heavy oil production Can. J. Chem. Eng. (IF 2.1) Pub Date : 2024-03-17 Xinfeng Jia, Kangkang Wang, Jian Xiong, Binhai Jiao, Dong Liu, Zhangxin Chen, Liangliang Jiang, Zhanxi Pang
As one the most important recovery mechanisms of steam-assisted gravity drainage (SAGD), gravity drainage is largely dependent on the inclination angle of the steam chamber edge. The existence of solution-gas causes an ellipsoid-shaped chamber that has small inclination angle at the bottom, which leads to inefficient gravity drainage and slows down oil production. To address this problem, this study
