casing pressure การใช้

• Once all the contaminant has been circulated out, the casing pressure should have reached zero.
• To remedy this problem, a reinforced case was produced and Kynoch made a reduced load to lower the case pressure.
• Tubing and casing pressures cause the valve to open and close, thus allowing gas to be injected into the fluid in the tubing to cause the fluid to rise to the surface.
• He was assigned to work on secret projects : he constructed a radio mast to replace the Moscow one and built a huge underground refuge for the Moscow government, in case pressure from German troops forced their evacuation.
• On Nov . 11, 1999, barely into the first month of Marlin's operation, Bob Merchant, the man responsible for running the platform, was called out of his office to look at a casing pressure gauge at a wellhead.
• A "'squeeze manifold "'is a compact arrangement of valves and pressure gauges that allows monitoring of the drill pipe and casing pressures throughout the job, and facilitates quick switching of the pumping pressure to either side while the fluid returning from the other side of well is directed to the mud pit or a disposal pit or tank.
