The oil leak was discovered on the afternoon of 22 April 2010 when a large oil slick began to spread at the former rig site. [41] The oil flowed for 87 days. BP originally estimated a flow rate of 1,000 to 5,000 barrels per day [bbl/d] (160 to 790 m 3 /d).
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.
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 ...
Consider installing a flow-based water-leak detection device that automatically shuts off the water supply when a leak is detected. Some devices may even send alerts to your phone to notify you of ...
