v: The operation of screwing one pipe into another female connection.

n: a temporary platform erected in the derrick or mast some 20 to 40 feet (6-12 metres) above the derrick floor. The derrickhand or another crew member works on the board while casing is being run in a well. The board may be wooden or fabricated of steel girders floored with antiskid material and powered electrically to be raised or lowered to the desired level. A stabbing board serves the same purpose as a monkeyboard but is temporary instead of permanent.

n: A temporary platform in the derrick ,20 to 40 feet above the floor,on which a crewman works while casing is being run to guide a joint while it is being screwed into the joint in the rotary table.

n: a protective device, usually made of rubber, that fits on the outside diameter of the box of the pipe that is in the hole. It has a funnel-shaped top and serves as a cushion and guide for stabbing pipe.

n: A device used to protect the female connection when stabbing .

n: a special drill stem valve that, when in open position, allows fluid to flow through it, thus allowing the valve to be stabbed into the drill stem.

n: I. the ability of a ship or mobile offshore drilling rig to return to an upright position when it has rolled to either side because of an external force (such as waves). 2. the ability of a measuring instrument to maintain its accuracy over a long period.

adj: said of a flowing well when its rate of production through a given size of choke remains constant, or, in the case of a pumping well, when the fluid column within the well remains constant in height.

n: the bottomhole flowing pressure that has been allowed time to reach a steady state.

n: the bottomhole shut-in pressure that has been allowed time to reach a steady state.

n: condensate that has been stabilized to a definite vapor pressure in a fractionation system.

n: 1. a tool placed on a drill collar near the bit that is used, depending on where it is placed, either to maintain a particular hole angle or to change the angle by control- ling the location of the contact point between the hole and the collars. See packR:d-hole as- sembly. 2. a vessel in which hydrocarbon vapors are separated from liquids. 3. a fractionation system that reduces the vapor pressure so that the resulting liquid is less volatile.

n: A downhole tool which has minor interspace with borehole,usually be fixed on the drill string.
