a perforating process involving pumping a slurry of liquid and size particles through a nozzle to cut through steel and rock.

n: a bottle-shaped steel cylinder located in a blowout preventer control unit to store nitrogen and hydraulic fluid under pressure (usually at 3,(XK)pounds per square inch). The fluid is used to actuate the blowout preventer stack.

n: a method of joining steel components in which acetylene gas and oxygen are mixed in a torch to attain the high temperatures necessary for welding. As an early type of welding (it was also called oxyacetylene welding),its primary disadvantage was the seepage of molten weld material onto the interior surface of the pipe, often leading to corrosion problems.

abbr: aluminum cable steel- reinforced conductor.

n: The drill pipe made by alloy of titanium and aluminium. It is lighter than the isometric drill pipe made by steel. It improves the drilling depth of rig, has good fatigue resistence and can absorb shake when connected above the drill collar.

n: an alloy of copper and aluminum that may also include iron, manganese, nickel, or zinc. aluminum cable steel-reinforced

a steel with a microstructure consisting of austentite at room temperature.

n: a cylindrical steel bar (similar to the handle or bail of a bucket, only much larger) that supports the swivel and connects it to the hook. Sometimes, the two cylindrical bars that support the elevators and attach them to the hook are called bails or links. v: to recover bottomhole fluids, samples, or drill cuttings by lowering a cylindrical vessel called a bailer to the bottom of a well, filling it, and retrieving it.

n: A rounded steel bar that supports the swivel and connects it to the hook. May also apply to the steel bars that connect the elevators to the hook (links).

remove solids or fluids from a well.

a steel, aluminum, brass or plastic ball pumped or dropped downhole to shift or operate a tool.
