Company Profile:
The Petroleum Extension Service (PETEX) is a unit of the Division of Continuing Education at The University of Texas at Austin and has been training companies and individuals since 1944.
A device mounted near the drawworks drum to keep the driller from inadvertently raising the travelling block into the crown block. A probe senses when too much line has been pulled onto the drum, indicating that the travelling block may strike the crown. The probe activates a switch that simultaneously disconnects the drawworks from its power source and engages the drawworks brake.

Ram
The closing and sealing component on a blowout preventer. One of three types—blind, pipe, or shear—may be installed in several preventers mounted in a stack on top of the wellbore. Blind rams, when closed, form a seal on a hole that has no drill pipe in it; pipe rams, when closed, seal around the pipe; shear rams cut through drill pipe and then form a seal.
Industry:Oil & gas
A blowout preventer that uses rams to seal off pressure on a hole that is with or without pipe. It is also called a ram preventer. Ram-type preventers have interchangeable ram blocks to accommodate different O.D. drill pipe, casing, or tubing.
Industry:Oil & gas
Unrefined liquid petroleum. It ranges in gravity from 9°API to 55°API and in colour from yellow to black.
Industry:Oil & gas
In sucker rod pumping, the difference between the polished rod peak load on the upstroke and the minimum load on the downstroke.
Industry:Oil & gas
A measure of the speed at which the bit drills into formations, usually expressed in feet (meters) per hour or minutes per foot (meter).
Industry:Oil & gas
The speed, measured in revolutions per minute, at which the rotary table is operated.
Industry:Oil & gas
An area of deck grating removed to clear an obstruction or to permit pipes, ducts, columns, and the like to pass through the grating.
Industry:Oil & gas
A strong but relatively lightweight device used on some rigs that employ a top drive to rotate the bit. Although a conventional rotary table is not required to rotate the bit on such rigs, crew members must still have a place to set the slips to suspend the drill string in the hole when tripping or making a connection. A rotary support table provides such a place but does not include all the rotary machinery required in a regular rotary table.
Industry:Oil & gas
The fragments of rock dislodged by the bit and brought to the surface in the drilling mud. Washed and dried cuttings samples are analysed by geologists to obtain information about the formations drilled.
