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 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. A cleaning pig for a 150-millimetre (6 in) oil pipeline. The wire brush encircles the shaft and scours the interior of the pipeline.
A detailed inventory of greenhouse gas emissions from upstream oil and gas activities in Canada for the year 2000 estimated that fugitive equipment leaks had a global warming potential equivalent to the release of 17 million metric tonnes of carbon dioxide, or 12 percent of all greenhouse gases emitted by the sector, [9] while another report put fugitive emissions at 5.2% of world greenhouse ...
Pipe cleaners are usually made two at a time, as the inner wires of each pipe cleaner have the yarn wrapped around them, making a coil, the outer wires trap the wraps of yarn, which are then cut, making the tufts. Chenille yarn is made in much the same way, which is why craft pipe cleaners are often called "chenille stems". The word "chenille ...

A Larimer County man's 11-month journey to stop leaks at an oil storage facility near his home illustrates gaps in enforcement, conservationists say.
In addition to casings, oil wells usually contain a "production liner" or "production tubing", which is another set of steel pipes suspended inside the casing. The "annulus" between the casing and the production liner is filled with "mud" of a specific density to "balance" the pressure inside the casing with the "pore pressure" of fluids in the ...
