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 tubular section of pipe that is threaded inside and used to connect two joints of casing.
Industry:Oil & gas
An electric well log in which the conductivity of the formation rather than the resistivity is measured. Because oil-bearing formations are less conductive of electricity than water-bearing formations, an induction survey, when compared with resistivity readings, can aid in determination of oil and water zones.
Industry:Oil & gas
A wrench that is used to make up or break out drill pipe, tubing, or casing on which the torque is provided by air or fluid pressure. Conventional tongs are operated by a mechanical pull provided by a jerk line connected to a cathead.
Industry:Oil & gas
The employees of a company that specialises in preparing and running casing into a well.
Industry:Oil & gas
A packer with an element that inflates by means of gas or liquid pumped from the surface through a line. It is deflated by means of slots that can be opened to allow the gas or liquid to flow out. They are used when a temporary packer is needed in a hole.
Industry:Oil & gas
A heavy cylindrical body, fitted with a set of knives, used to cut and free a section of casing in a well.
Industry:Oil & gas
The hole made by the drilling bit, which can be open, cased, or both. Also called borehole, hole, or wellbore.
Industry:Oil & gas
1. a high-pressure gas injected into a formation to maintain or restore reservoir pressure. 2. gas injected in gas-lift operations.
Industry:Oil & gas
1. an injection of water prior to chemical flooding that is used to induce reservoir conditions favourable to the surfactant solution by adjusting reservoir salinity and reducing ion concentrations. A preflush may also be used to obtain advance information on reservoir flow patterns. 2. fluid injected prior to the acid solution pumped into a well in an acid-stimulation treatment; sometimes called a spearhead. Compare overflush.
