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.
The tendency of proppants to separate from fracture fluid when the speed, or velocity, of the fluid is low.
Industry:Oil & gas
An oilwell-surveying method that determines the direction and angle of formation dip in relation to the borehole. It records data that permit computation of both the amount and direction of formation dip relative to the axis of the hole and thus provides information about the geologic structure of the formation. Also called dipmeter log or dip log.
Industry:Oil & gas
1. intentional deviation of a wellbore from the vertical. Although wellbores are normally drilled vertically, it is sometimes necessary or advantageous to drill at an angle from the vertical. Controlled directional drilling makes it possible to reach subsurface areas laterally remote from the point where the bit enters the earth.
Industry:Oil & gas
A string of tubing or pipe, usually 3/4 or 1 inch (1.9 or 2.54 centimeters) in diameter.
Industry:Oil & gas
A wellbore intentionally drilled at an angle from the vertical. See directional drilling.
Industry:Oil & gas
1. the use of water-flooding or gas injection to maintain formation pressure during primary production and to reduce the rate of decline of the original reservoir drive. 2. water-flooding of a depleted reservoir. 3. the first improved recovery method of any type applied to a reservoir to produce oil not recoverable by primary recovery methods. See primary recovery.
Industry:Oil & gas
In well cementing, the fluid, usually drilling mud or salt water, that is pumped into the well after the cement is pumped into it to force the cement out of the casing and into the annulus.
Industry:Oil & gas
Natural gas that is in solution with crude oil in the reservoir.
Industry:Oil & gas
To attach a joint or stand of drill pipe onto the drill stem suspended in the wellbore to permit deepening the wellbore by the length of the pipe.
Industry:Oil & gas
A source of natural reservoir energy in which the dissolved gas coming out of the oil expands to force the oil into the wellbore. Also called solution-gas drive. See reservoir drive mechanism.
