Petrobank Energy & Resources Ltd. said production from its Kerrobert in situ combustion project in southwestern Saskatchewan increased in March to an average 264 b/d of apparently upgraded bitumen (OGJ Online, Feb. 1, 2012).
The company is using its proprietary THAI technology in the project, production of which in January and February averaged 155 b/d. To support combustion, it injects air through vertical wells drilled near the toes of horizontal producing wells.
That the produced oil has average API gravity of 13-14º indicates upgrading is occurring in situ, Petrobank says. The reservoir oil is 10.4º gravity.
The company brought Kerrobert field on production last September.
