BP (BP) re-capped its leaking oil well in the Gulf of Mexico after an accident involving an underwater robot forced the company to remove the cap. It was refitted over the leak late Wednesday on ...
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.
These devices are known as packers and are used to make a seal between the borehole wall and the drill pipe, isolating the region of interest. [3] A valve is opened, reducing the pressure in the drill stem to surface pressure, causing fluid to flow out of the packed-off formation and up to the surface.
The leak was in one of the lines It delayed the test overnight because of a leak in the equipment on the seafloor. BP Fixes Leak That Delayed Key Test of Oil Well Cap
A well control company then will need to extinguish the well fire or cap the well, and replace the casing head and other surface equipment. If the flowing gas contains poisonous hydrogen sulfide , the oil operator might decide to ignite the stream to convert this to less hazardous substances.
After a 24 hour delay, BP (BP) is proceeding with an all important "integrity test" that will determine whether its damaged well in the Gulf of Mexico can be safely capped and closed prior to the ...
CITHP – closed-in tubing head pressure (tubing head pressure when the well is shut in) CIV – chemical injection valve; CK – choke (a restriction in a flowline or a system, usually referring to a production choke during a test or the choke in the well control system) CL – core log; CLG – core log and graph; CM – choke module
This is a welded/machined product which contains a "side pocket" alongside the main tubular conduit. The side pocket, typically 1" or 1½" diameter is designed to contain gas lift valve, which allows flow of High pressure gas into the tubing there by reducing the tubing pressure and allowing the hydrocarbons to move upwards.
