1904 oil well fire at Bibi-Eibat (near Baku, Azerbaijan). Oil well control is one of the most important aspects of drilling operations. Improper handling of kicks in oil well control can result in blowouts with very grave consequences, including the loss of valuable resources and also lives of field personnel. Even though the cost of a blowout ...
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.
CK – choke (a restriction in a flowline or a system, usually referring to a production choke during a test or the choke in the well control system) CL – core log; CLG – core log and graph; CM – choke module; CMC – crown mounted compensators; CMC – critical micelle concentration; CMP – common midpoint (geophysics)
the drilling and operating companies well control policies. For workover or completion operations, other methods are often used. Bullheading is a common way to kill a well during workovers and completions operations but is not often used while drilling. Reverse circulation is another kill method used for workovers that are not used for drilling ...
Example of a map used by reservoir engineers to determine where to drill a well. This screenshot is of a structure map generated by contour map software for an 8500 ft deep gas and oil reservoir in the Earth field, Vermilion Parish, Erath, Louisiana. The left-to-right gap near the top of the contour map indicates a fault line. This fault line ...
The BOP valve affixed to the wellhead could be closed in the event of drilling into a high pressure zone, and the well fluids contained. Well control techniques could be used to regain control of the well. As the technology developed, blowout preventers became standard equipment, and gushers became a thing of the past.
This, of course, runs a high risk of causing well damage. The most effective way is to use coiled tubing, pumping the gas/diesel down the coil and circulating out the bottom into the well bore, where it will displace the kill mud to production. (Of course, getting a coiled tubing spread to the location may take weeks of work and logistics.)
Founded in 1975, Wild Well is the world's leading provider of onshore and offshore well control emergency response, pressure control, relief well planning, engineering, and training services. Wild Well Control was founded by Joe R. Bowden Sr. in 1975 (July 15, 1932 – November 12, 2006). [3] Its main competition was Red Adair and Company.
