In order to save the space of offshore oil recovery platform and improve the space utilization rate, SanJack successfully developed Single column dual-well thermal recovery wellhead in 2011.
With a height of 3.6m and a weight of 7.8T, the wellhead can realize integrated operation of offshore steam injection and oil recovery.
It is two separate wellheads mounted in a single well slot that can work independently. The Single column dual-well thermal recovery wellhead effectively saves the platform space, improves the utilization rate of the platform, and relatively improves the oil recovery of the platform. The wellhead has obtained the national patent.
