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 cone-shaped device, a hydrocyclone, designed to remove very fine solid particles from the drilling mud.
Industry:Oil & gas
The control valves, pressure gauges, and chokes assembled at the top of a well to control flow of oil and/or gas after the well has been drilled and completed. It is used when reservoir pressure is sufficient to cause reservoir fluids to rise to the surface.
Industry:Oil & gas
An employee of a drilling fluid supply company whose duty it is to test and maintain the drilling mud properties that are specified by the operator.
Industry:Oil & gas
To pass from one point throughout a system and back to the starting point. For example, drilling fluid is circulated out of the suction pit, down the drill pipe and drill collars, out the bit, up the annulus, and back to the pits while drilling proceeds.
Industry:Oil & gas
An accessory attached to the top of the drill pipe or tubing to form a connexion with the mud system to permit circulation of the drilling mud.
Industry:Oil & gas
A tubular, perforated device attached to the bottom of a suckerrod pump that helps to prevent gas lock. The device works on the principle that gas, being lighter than oil, rises. As well fluids enter the anchor, gas breaks out of the fluid and exits from the anchor through perforations near the top. Remaining fluids enter the pump through a mosquito bill (a tube within the anchor), which has an opening near the bottom. In this way, all or most of the gas escapes before the fluids enter the pump.
Industry:Oil & gas
The pressure generated by the mud pumps and exerted on the drill stem.
Industry:Oil & gas
A free-gas phase overlying an oil zone and occurring within the same producing formation as the oil. See reservoir.
Industry:Oil & gas
The recording of information derived from examination and analysis of formation cuttings made by the bit and of mud circulated out of the hole. A portion of the mud is diverted through a gas-detecting device. Cuttings brought up by the mud are examined under ultraviolet light to detect the presence of oil or gas. Mud logging is often carried out in a portable laboratory set up at the well site.
