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
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.
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.
Log ASCII standard (LAS) is a standard file format common in the oil-and-gas and water well industries to store well log information. Well logging is used to investigate and characterize the subsurface stratigraphy in a well. A single LAS file can only contain data for one well, but it can contain any number datasets (called "curves") from that ...
A top kill is a procedure used as a means of regaining control over an oil well that has been producing or is experiencing well control issues with crude oil or natural gas in the well. It is not a procedure where control has been lost over the well, like a blowout. The process involves pumping heavyweight drilling mud into the well. This ...
