a failure mode that can cause the cancellation-of or immediate-halt-to a project or event. Generally expressed as a percent probability.

canisters of hydraulic fluid, pressurized with a nitrogen gas cap of sufficient pressure and volume to operate all the rams on a BOP in case of power failure to the BOP.

(failure/crack development): characteristic markings (ridges, tears, risers, etc.) on fracture surfaces after fatigue crack of fracture propagation (also known as beach marks, clamshell marks, and conchoidal marks).

characteristic markings (ridges, tears, risers, etc.) on fracture surfaces after fatigue crack of fracture propagation (also known as clamshell marks, conchoidal marks and arrest marks).

an engineered sequence of choke settings in the start-up of a well to apply stresses in the formation in a manner that will strengthen the formation and avoid failure.

n: 1. a failure of equipment.2. in a fracture treatment or a squeeze job, the failure of formation rock to withstand pressure, allowing it to rupture. adj: pertaining to the amount of pressure needed at the wellhead to rupture the formation in a fracture treatment or a squeeze job (as in formation breakdown pressure).

fracture.

n: The abruption whose feature is not ductile or scuffing.

venting of fluids to surface through channels in cement or behind pipe (well control barrier failure) or unintended fracturing into a adjacent formation.

n: The casing fractures or wear out due to corruption, friction or striking.
