n: a wireline instrument for measuring bottomhole temperature or pressure. It contains a clock-driven recording section and either a pressure element or a temperature element. It is thin enough to pass downhole through small tubing.

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.

abbr: bottomhole temperature.

bottom hole temperature.

n: a thick-walled container, usually steel, used to hold devices that determine and record pressure or temperature in a wellbore. See bonomhole pressure.

a thick walled pressure container of pressure measuring instruments or a sample container.

n: a mechanism for anchoring a bottomhole pump in a well;located on the lower end of the pump. Compare top hold-down.

n: the portion of the drilling assembly below the drill pipe. It can be very simple - composed of only the bit and drill collars - or it can be very complex and made up of several drilling tools.

n: the lowest or deepest part of a well. adj: pertaining to the bottom of the wellbore.

n: a device with a restricted opening placed in the lower end of the tubing to control the rate of flow. See choke.

n: a contract providing for the payment of money or other considerations upon the completion of a well to a specified depth.

n: A contract that payment when well completion if this well is drilled to the authorized depth.

n: see bottomhole choke.
