A broken pipe was taken out on July 11 and replaced with a flange spool resembling a pipe, on top of which the new cap was located. [26] [27] The well integrity test was scheduled to take place after the installation of a three-ram capping stack over the lower marine riser package of the Deepwater Horizon semi-submersible rig on July 13. On ...
April 19, 2011 – Well blowout in Bradford County, Pennsylvania. [136] March 28, 2012 – An explosion at a natural gas compression station in Susquehanna County. [137] May 19, 2012 – Leroy Twp., Contamination from leaking gas well, [138] May 15, 2013 – A fire and possible explosion, at a Susquehanna County gas compressor station. [139]
May 7 – A 125-tonne (276,000 lb) container dome is lowered over the largest of the well leaks and pipe the oil to a storage vessel on the surface. [54] May 8 – BP reports that methane is freezing at the top of the dome making it ineffective. [51] May 9 – Tar balls reported on Dauphin Island in Alabama.
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.
The result was 25 – 28 leaking well heads buried beneath the sea floor at approximately 475 feet (145 m) below the surface. [10] At the moment of capsizing, more than 600 barrels of crude oil, each containing 42 gallons, tumbled into the Gulf. The rig, leaking oil, was buried in 150 feet of mud. [4] [11] [10]
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.
Spectral noise logging (SNL) is an acoustic noise measuring technique used in oil and gas wells for well integrity analysis, identification of production and injection intervals and hydrodynamic characterisation of the reservoir. SNL records acoustic noise generated by fluid or gas flow through the reservoir or leaks in downhole well components.
Pipe replacement by pipe bursting. Pipe bursting is a trenchless method of replacing buried pipelines (such as sewer, water, or natural gas pipes) without the need for a traditional construction trench. "Launching and receiving pits" replace the trench needed by conventional pipe-laying.
