May 21 – BP begins live underwater video broadcasts of the leak. [64] Flow Rate Technical Group established for "scientifically validated information about the amount of oil flowing from BP s leaking oil well." [26] The average daily oil collection rates is 2,000 barrels (84,000 US gallons; 320,000 litres) a day. [65] [66]
[7] [8] The second technique, placing a 125-tonne (276,000 lb) containment dome (which had worked on leaks in shallower water) over the largest leak and piping the oil to a storage vessel on the surface, failed when gas leaking from the pipe combined with cold water formed methane hydrate crystals that blocked the opening at the top of the dome ...
Shut-in drill pipe pressure (SIDPP), which is recorded when a well is shut in on a kick, is a measure of the difference between the pressure at the bottom of the hole and the hydrostatic pressure (HSP) in the drillpipe. During a well shut-in, the pressure of the wellbore stabilizes, and the formation pressure equals the pressure at the bottom ...
Pipe plugs are used with supplementary accessories such as air and water hoses, air and pressure control devices, gauges, adapters and chains depending on the type of the pipe plug and the process. Auxiliary equipment like compressors for inflating the pipe plugs, water tanks for filling the pipeline and pumps for some cases must be used.

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.
The Soviets lowered a specially made 30 kiloton nuclear physics package into a 6-kilometre (20,000 ft) borehole drilled 25 to 50 metres (82 to 164 ft) away from the original (rapidly leaking) well. A nuclear explosive was deemed necessary because conventional explosives both lacked the necessary power and would also require a great deal more ...
By 2012, corrosion leaks had only occurred in two large pipelines worldwide. Leaks due to military-type acts and mishaps were considered "very unlikely". The largest leak in the analysis was defined as a "full-bore rupture (>80 mm [3.1 in])", for example from a sinking ship hitting the pipeline. Such an unlikely large leak from 54 metres (177 ...
