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.
1. the activities and methods of preparing a well for the production of oil and gas or for other purposes, such as injection; the method by which one or more flow paths for hydrocarbons are established between the reservoir and the surface. 2. the system of tubulars, packers, and other tools installed beneath the wellhead in the production casing; that is, the tool assembly that provides the hydrocarbon flow path or paths.
Industry:Oil & gas
A circular device with a frictional gripping arrangement of slips and packing rings used to suspend casing from a casing head in a well.
Industry:Oil & gas
A survey used to determine the injection profile, that is, to assign specific volumes or percentages to each of the formations taking fluid in an injection well. The injection log is also used to cheque for casing or packer leaks, proper cement jobs, and fluid migration between zones.
Industry:Oil & gas
The method of producing a gas reservoir that is not associated with a water drive. Gas is removed and reservoir pressure declines until all the recoverable gas has been expelled.
Industry:Oil & gas
The methods used to control a kick and prevent a well from blowing out. Such techniques include, but are not limited to, keeping the borehole completely filled with drilling mud of the proper weight or density during operations, exercising reasonable care when tripping pipe out of the hole to prevent swabbing, and keeping careful track of the amount of mud put into the hole to replace the volume of pipe removed from the hole during a trip.
Industry:Oil & gas
A heavy, flanged steel fitting connected to the first string of casing. It provides a housing for slips and packing assemblies, allows suspension of intermediate and production strings of casing, and supplies the means for the annulus to be sealed off. Also called a casing spool.
Industry:Oil & gas
Water that is introduced into a reservoir to help drive hydrocarbons to a producing well.
Industry:Oil & gas
The fluid, usually a combination of gas, oil, water, and suspended sediment, that comes out of a reservoir. Also called well stream.
Industry:Oil & gas
The depth in a well at which casing is set, generally the depth at which the casing shoe rests.
Industry:Oil & gas
A well through which fluids are injected into an underground stratum to increase reservoir pressure and to displace oil. Also called input well.
