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 large BOP (q.v.) valve that forms a seal in the annular space between the wellbore and the drill pipe. It is usually installed above the ram type preventers in the BOP stack.

a elastomer bag or donut type seal, pushed into contact with the pipe or tools in the blow out preventer (BOP). It is designed to seal around pipe or any other irregular surface tool (packers, guns, pumps, etc.) that may be in the BOP. May also be called

n: the assembly of well-control equipment including preventers. spools. valves. and nipples connected to the top of the wellhead.

abbr: blowout preventer equipment. BOP stack n: the assembly of blowout preventers installed on a well.

n: a pipe attached to the blowout preventer stack out of which kick fluids and mud can be pumped to the choke manifold when a blowout preventer is closed in on a kick.

n: A high-pressure pipe leading from an outlet on the BOP stack to the backpressure choke and associated manifold. During well-control operations, the fluid under pressure in the wellbore flows out of the well through the choke line to the choke, reducing th

a drilling and workover pressure control device. A line that attached to the BOP stack and through which kick fluids can be circulated when the BOP is closed.

n: the equipment for transporting and using coiled tubing, including a reel for the coiled tubing, an injector head to push the tubing down the well, a wellhead blowout preventer stack, a power source (usually a diesel engine and hydraulic pumps),and a control console. A unique feature of the unit is that it allows continuous circulation while it is being lowered into the hole. A coiled tubing unit is usually mounted on a trailer or skid.

n: a condition in which clay platelets remain stacked by a polyvalent cation, such as calcium, and are deflocculated by use of a thinner.

n: The condition in which the clay platelets are maintained stacked by a polyvalent cation, such as calcium.

n: 1. a buried anchor to which guy wires are tied to steady the derrick, mast, stacks, and so on. 2. an anchoring point against which the winch on a boring machine for pipe lining can pun.

n: A buried anchor to which guy-wires are tied to steady the derrick, boiler stacks, etc.

buried anchor.

n: refer to diverter
