... 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...

... to its high density, viscosity, and high pour point characteristics, heavy oil development faces significant challenges, rendering conventional techniques ineffective (Miao, 2018). Steam stimulation, steam drive, and steam-assisted gravity drainage (SAGD) are the most commonly used heavy oil extraction...

... Abstract This paper analyzed the steam communication among steam chambers made by the well pad system for steam assisted gravity drainage. The typical well pad system consisted of several well pairs so that steam communication between well pairs would be inevitable. This study introduced two...

... ABSTRACT This paper presented the optimal operation strategy of Fast-SAGD(Steam Assisted Gravity Drainage) process considering steam channeling among vapor chambers. To accomplish minimum cSOR(cumulative Steam to Oil Ratio), it was energetically efficient to start CSS(Cyclic Steam Stimulation...

... ABSTRACT SAGD (Steam Assisted Gravity Drainage) has been a primary production method with its successive performance for recovering viscous oil sands. If water- or gas-bearing zone is located nearby the bitumen layer, the significant heat loss occurs into these layers (i.e. thief zone) so...
