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]
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.
A leak appearing within an analytic region (a rule added to the camera) is immediately analyzed for its attributes, including thermal temperature, size, and behaviour (e.g. spraying, pooling, spilling). When a leak is determined to be valid based on set parameters, an alarm notification with leak video is generated and sent to a monitoring station.
Regularly, for example once a month per well, the flow from one and only one selected well is led into the test separator for determining well flow rate for the selected well. [3] The separator divides the flow from the well into the streams of individual products which typically are oil, gas and water, but may include natural-gas condensate ...
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 ...
[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 ...
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 ...
The blue plastic disks seal against the inside of the pipe to propel the device and to remove loose sedimentation or scale buildup. The black rectangles at the top and the circular disks in the center are magnets to attract and remove any loose metal objects in the pipe. An ultrasonic leak-detection pig.
