a device that is attached to the shaft of the drawworks and used as a power source for making up joints of pipe. It is usually located on the driller’s side of the drawworks. Also called spinning cathead.
Industry:Oil & gas
a survey run in cased holes to locate the top of the cement in the annulus. Since cement generates a considerable amount of heat when setting, a temperature increase will be found at the level where cement is found behind the casing.
Industry:Oil & gas
1. the crown block or top of a derrick or mast. 2. the top of a piston. 3. a high spot formed on a tool joint shoulder as the result of wobble.
Industry:Oil & gas
tongs used for screwing one length of pipe into another for making up a joint. Compare breakout tongs. See also tongs.
Industry:Oil & gas
an operation used to determine temperatures at various depths in the wellbore. It is also used to determine the height of cement behind the casing and to locate the source of water influx into the wellbore.
Industry:Oil & gas
an assembly of sheaves or pulleys mounted on beams at the top of the derrick. The drilling line is run over the sheaves down to the hoisting drum.
Industry:Oil & gas
a pipe, coupling, or tool that has threads on the outside so that it can be joined to a female connection.
Industry:Oil & gas
1. the use of improved recovery methods that not only restore formation pressure but also improve oil displacement or fluid flow in the reservoir. 2. the use of any improved recovery method to remove additional oil after secondary recovery. Compare primary recovery, secondary recovery.
Industry:Oil & gas
a device mounted near the drawworks drum to keep the driller from inadvertently raising the traveling block into the crown block. A probe senses when too much line has been pulled onto the drum, indicating that the traveling block may strike the crown. The probe activates a switch that simultaneously disconnects the drawworks from its power source and engages the drawworks brake.
Industry:Oil & gas
a cylindrical bar, spindle, or shaft around which other parts are arranged or attached or that fits inside a cylinder or tube.
