Mechanical Integrity Test
Definition - What does Mechanical Integrity Test mean?
Mechanical Integrity Test is a test that consists of two parts conducted on an injection well to ensure that there is no leak in the well and the mechanical components of the well function in a way that is protective of human health and the environment. The injection well has two parts –internal and external. The internal part has mechanical integrity if no leakage is noted in the packer, casing or tubing. The external part has mechanical integrity if no movement of fluid is noted through the vertical channels that are adjacent to the injection borehole.
Petropedia explains Mechanical Integrity Test
Mechanical Integrity Test should be designed in a way that it determines if there is any leak found in the casing, packer or tubing of a well. It must also determine if there is movement of the injected fluid between or into the USDWs through the vertical channels that are adjacent to the borehole. If the test determines there are no leaks in the casing, tubing or packer of the well, it must include a tubing-casing annulus pressure test, timed run method or radioactive tracer survey. If no movement of the fluid is observed then the test is required to include a demonstration that consists of cement bond log.
