to place a packer in the wellbore and activate it so that it forms a seal between the tubing and the casing.
Industry:Oil & gas
the performance of one or more of a variety of remedial operations on a producing well to try to increase production. Examples of workover jobs are deepening, plugging back, pulling and resetting liners, and squeeze cementing. See recompletion.
Industry:Oil & gas
a drilling rig on which the energy from the power source—usually diesel engines—is changed to electricity by generators mounted on the engines. The electrical power is then distributed through electrical conductors to electric motors. The motors power the various rig components. Compare mechanical rig.
Industry:Oil & gas
a saturated aliphatic hydrocarbon having the formula CnH2n+2 (for example, methane, CH4; ethane, C2H6). Heavier paraffin hydrocarbons (for example, C18H38) form a waxlike substance that is called paraffin. These heavier paraffins often accumulate on the walls of tubing and other production equipment, restricting or stopping the flow of the desirable lighter paraffins.
Industry:Oil & gas
a special drilling mud used to keep a well under control while it is being worked over. A workover fluid is compounded carefully so that it will not cause formation damage.
Industry:Oil & gas
a form of artificial lift that utilizes an electric submersible multistage centrifugal pump. Electric power is conducted to the pump by a cable attached to the tubing.
Industry:Oil & gas
a tube with guides around it to keep it centered in the hole, and a cylindrical piece with blades attached. Spaces between the blades allow drilling fluid to pass through and carry away the scrapings.
Industry:Oil & gas
in a multiple completion, the arrangement of a separate tubing string for each zone produced, with all zones isolated by packers.
