The large, flanged spool in the drawworks on which the hoisting cable is wound. See drawworks.
Industry:Oil & gas
A part of the brake mechanism consisting of a flexible steel band lined with a material that grips a drum when tightened. On drawworks, the brake band acts on the drum to control the lowering of the travelling block and its load.
Industry:Oil & gas
A type of improved recovery in which heat is introduced into a reservoir to lower the viscosity of heavy oils and to facilitate their flow into producing wells. The pay zone may be heated by injecting steam (steam drive) or by injecting air and burning a portion of the oil in place (in situ combustion).
Industry:Oil & gas
To start the mud pump for restoring circulation of the mud column. Because the stagnant drilling fluid has thickened or gelled during the period of no circulation, higher pump pressure is usually required to break circulation.
Industry:Oil & gas
The system on the rig that performs all the lifting on the rig, primarily the lifting and lowering of drill pipe out of and into the hole. It is composed of drilling line, travelling block, crown block, and drawworks. See also hoisting components.
Industry:Oil & gas
One of a series of devices that continuously monitor the level of the drilling mud in the mud tanks. The indicator usually consists of float devices in the mud tanks that sense the mud level and transmit data to a recording and alarm device (a pit-volume recorder) mounted near the driller’s position on the rig floor. If the mud level drops too low or rises too high, the alarm may sound to warn the driller of lost circulation or a kick.
Industry:Oil & gas
1. to unscrew one section of pipe from another section, especially drill pipe while it is being withdrawn from the wellbore. During this operation, the tongs are used to start the unscrewing operation. 2. to separate, as gas from a liquid or water from an emulsion.
Industry:Oil & gas
The arm that connects the crank to the walking beam on a pumping unit by means of which rotary motion is converted to reciprocating motion.
Industry:Oil & gas
