As an important achievement of the Foam Cementing Technology of the Petroleum Engineering Technology Research Institute and the large-scale cementing equipment independently developed at home, the liquid nitrogen foam cement cementing automation equipment adopts advanced ultra-low temperature liquid nitrogen evaporation control technology and unique high-pressure gas injection
What Westport has done is take direct high-pressure gas injection
to another level of technological innovation and adaptability.
are currently doing a job they were not designed to do, which is withstand cycles of high-pressure gas injections
and withdrawals - many through a single pipe without backup safety valves to prevent blowouts (i.e., 'Aliso Canyon-type' wells).
