... efficiency. Zhang et al. (2015) investigated heat loss and casing damage in the Steam-assisted gravity drainage (SAGD) process in the Liaohe oilfield. They indicated that VIT reduced heat loss by 60% when compared to conventional tubing. Furthermore, when VIT was applied, the possibility of damage...

... drainage (SAGD) are the most commonly used heavy oil extraction technologies globally(LI, et al., 2007). Abundant heavy oil resources are discovered in Bohai oilfield, and various fields such as NB35-2 and LD5-2N have been developed using steam flooding and steam drive methods since 2008. It provides...
