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.
Organic compounds of hydrogen and carbon whose densities, boiling points, and freezing points increase as their molecular weights increase. Although composed of only two elements, hydrocarbons exist in a variety of compounds, because of the strong affinity of the carbon atom for other atoms and for itself. The smallest molecules of hydrocarbons are gaseous; the largest are solids. Petroleum is a mixture of many different hydrocarbons.
Industry:Oil & gas
1. a pipe fitting on which the external thread is larger than the internal thread to allow two pipes of different sizes to be connected. 2. a removable lining or sleeve inserted or screwed into an opening to limit its size, resist wear or corrosion, or serve as a guide.
Industry:Oil & gas
A type of corrosion that occurs when metals are exposed to hydrogen sulphide gas; it is characterised by minute cracks that form just under the metal’s surface.
Industry:Oil & gas
The reservoir drive mechanism in which oil is produced by the expansion of the underlying water and rock, which forces the oil into the wellbore. In general, there are two types of water drive: bottom-water drive, in which the oil is totally underlain by water; and edgewater drive, in which only a portion of the oil is in contact with the water.
Industry:Oil & gas
1. a rope of wire, hemp, or other strong fibers. 2. braided wire used to conduct electricity, often called power cable.
Industry:Oil & gas
The force exerted by a body of fluid at rest. It increases directly with the density and the depth of the fluid and is expressed in many different units, including pounds per square inch or kilopascals.
Industry:Oil & gas
On an engine, a device, powered by the engine, that moves coolant (water) through openings in the engine block, through the radiator or heat exchanger, and back into the block.
Industry:Oil & gas
A record showing variations in wellbore diameter by depth, indicating undue enlargement due to caving in, washout, or other causes. The calliper log also reveals corrosion, scaling, or pitting inside tubular goods.
Industry:Oil & gas
The water tank is used to store water that is used for mud-mixing, cementing, and rig cleaning.
Industry:Oil & gas
A mast mounted on a truck and capable of being erected as a single unit. See telescoping mast.
