A trough or pipe that is placed between the surface connexions at the wellbore and the shale shaker.
Industry:Oil & gas
The operation of hoisting the drill stem out of and returning it into the wellbore.
Industry:Oil & gas
To remove sand, scale, and other deposits from the producing section of the well to restore or increase production.
Industry:Oil & gas
1. a condition sometimes encountered in a pumping well when dissolved gas, released from solution during the upstroke of the plunger, appears as free gas between the valves. If the gas pressure is sufficient, the standing valve is locked shut, and no fluid enters the tubing. 2. a device fitted to the gauging hatch on a pressure tank that enables manual dipping and sampling without loss of vapor. 3. a condition that can occur when gas-cut mud is circulated by the mud pump. The gas breaks out of the mud, expands, and works against the operation of the piston and valves.
Industry:Oil & gas
One of a series of open tanks, usually made of steel plate, through which the drilling mud is cycled to remove sand and fine sediments.
Industry:Oil & gas
A well-servicing and workover rig that is mounted on a truck chassis.
Industry:Oil & gas
The tools or instruments, such as bailers and swabs, used to clean out an oilwell.
Industry:Oil & gas
A well that primarily produces gas. Legal definitions vary among the states.
Industry:Oil & gas
A measure of the density of a drilling fluid expressed as pounds per gallon, pounds per cubic foot, or kilogrammes per cubic metre. Mud weight is directly related to the amount of pressure the column of drilling mud exerts at the bottom of the hole.
Industry:Oil & gas
Drive energy supplied naturally (as a reservoir is produced) by the expansion of the gas cap. In such a drive, the gas cap expands to force oil into the well and to the surface. See reservoir drive mechanism.
