This is the most common method of a contingency well kill. If there is a sudden need to kill a well quickly, without the time for rigging up for circulation, the more blunt instrument of bullheading may be used. This involves simply pumping the kill fluid directly down the well bore, forcing the well bore fluids back into the reservoir. This ...
Well control is the technique used in oil and gas operations such as drilling, well workover and well completion for maintaining the hydrostatic pressure and formation pressure to prevent the influx of formation fluids into the wellbore.
“Kill” the well (prevent the flow of formation fluid, influx, from the reservoir into the wellbore); Seal the wellhead (close off the wellbore); Sever the casing or drill pipe (in case of emergencies). In drilling a typical high-pressure well, drill strings are routed through a blowout preventer stack toward the reservoir of oil and gas
Gas lift well: gas is fed into valves installed in mandrels in the tubing strip. The hydrostatic head is lowered and the fluid is gas lifted to the surface. Single-well alternate completions: in this instance there is a well with two zones. In order to produce from both the zones are isolated with packers.
Well intervention vessel Skandi Constructor. A well intervention, or well work, is any operation carried out on an oil or gas well during, or at the end of, its productive life that alters the state of the well or well geometry, provides well diagnostics, or manages the production of the well.
After lengthy preparations, BP (BP) and the government will begin a series of "injection tests" Monday evening to determine whether the damaged Deepwater Horizon oil well in the Gulf of Mexico is ...
Source: [42] A well kill procedure is an oil well control method. Once the well has been shut-in on a kick , proper kill procedures must be done immediately. The general idea in well kill procedure is to circulate out any formation fluid already in the wellbore during kick, and then circulate a satisfactory weight of kill mud called Kill Weight ...
Second, the various monitoring zones can be developed using standard well development equipment and procedures before the multilevel monitoring systems are installed in the wells. Finally, installing multilevel systems inside multi-screened wells may simplify the task of decommissioning the wells once they are no longer needed.
