A leak changes the hydraulics of the pipeline, and therefore changes the pressure or flow readings after some time. Local monitoring of pressure or flow at only one point can therefore provide simple leak detection. As it is done locally it requires in principle no telemetry. It is only useful in steady-state conditions, however, and its ...
Over many years, downhole noise logging tools proved effective in inflow and injectivity profiling of operating wells, [3] [4] leak detection, [5] [6] location of cross-flows behind casing, [7] and even in determining reservoir fluid compositions. [8] Robinson (1974) described how noise logging can be used to determine effective reservoir ...
The oil slick as seen from space by NASA's Terra satellite on 24 May 2010. The 2010 Deepwater Horizon oil spill in the Gulf of Mexico has been described as the worst environmental disaster in the United States, releasing about 4.9 million barrels (210 million US gal; 780,000 m 3) of crude oil making it the largest marine oil spill in history.
Cover outside water spigots. Before the temperature drops below 32 degrees, outdoor water spigots attached to homes should be opened to allow to drain water out, closed and then covered.
Pressure test wrongly interpreted. Drill pipe was run to 8,367 ft and was thought to be ready for mud displacement. During the "negative pressure test", for which there was no detailed procedure, a "no flow" result from the kill line was accepted, while a 1,400-psi result on the drill pipe was ignored. Leak not spotted soon enough.
Three men accused Sean “Diddy” Combs of rape and sexual assault in separate lawsuits filed Thursday that allege the rap impresario plied them with doctored drinks and then attacked them while ...

A leak noise correlator is an electronic device used for Leak Detection and as a leak locator to find leaks in pressurized water or gas lines.. Typically, microphones or acoustic sound sensors are placed in contact with the pipe, at two or more points, to record the sound emitted by a leak (e.g. a hissing noise) somewhere between the points.
