To determine if metal loss is occurring on the internal or external surface of a pipe, a separate eddy current sensor is utilized to indicate wall surface location of the anomaly. The unit of measure when sensing an MFL signal is the gauss or the tesla and generally speaking, the larger the change in the detected magnetic field, the larger the ...
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.
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]
A pipe-in-pipe system [1] is a form of plumbing where all water pipes are running inside another pipe. Its purpose is to ensure that any leaks in the innermost pipe will not leak into the building structure and can be detected, as well as make for easier change of any internal pipes with leakage without opening the walls.
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.

For deep well designs, the Sealed Gauge measuring principle is also used. From a depth of approx. 20 m, the relative pressure can only be compensated to a limited extent by the thin hose. The level sensor is then designed as an absolute pressure transmitter whose zero point is adjusted to the desired mean air pressure depending on the location ...
