Rotork pneumatic actuators installed on Canadian well pads

摘要

Over 80 Rotork CP, GP and RC200 pneumatic actuators have been installed on well pads in Alberta, Canada where they will be part of an in situ steam assisted gravity drainage (SAGD) oil sand extraction project. SAGD technology is used to extract bitumen oil from 800 metres below the surface of the earth. This process is a form of steam stimulation in which two horizontal wells drill into an oil reservoir, one a few metres above the other. High pressure steam is continuously injected into the upper wellbore to heat the oil and reduce its viscosity. The heated oil then drains into the lower wellbore where it can be pumped out. The water and oil are taken to a separation facility, where the water is then taken, recycled and re-converted into steam so the process can begin again. This process significantly reduces the impact on the environment, when compared to historic methods.
