a specially designed, self-propelled workover or drilling rig that is driven directly to the well site. Power from a carrier rig's hoist engine or engines also propels the rig on the road. A carrier rig may be a back-in type or a drive-in type.
Industry:Oil & gas
1. an arrangement of pulleys and wire rope used for lifting heavy objects; a winch or similar device. 2. the drawworks.
2. to raise or lift.
Industry:Oil & gas
the recording of the natural or induced radioactive characteristics of subsurface formations. A radioactivity log, also known as a radiation log or a nuclear log, normally consists of two recorded curves: a gamma ray curve and a neutron curve. Both help to determine the types of rocks in the formation and the types of fluids contained in the rocks.
Industry:Oil & gas
to begin operating 24 hours a day. Moving the rig and rigging up are usually carried on during daylight hours only. When the rig is ready for operation at a new location, crews break tour.
Industry:Oil & gas
to lower the drill stem, the tubing, the casing, or the sucker rods into the wellbore.
Industry:Oil & gas
1. steel pipe placed in an oil or gas well to prevent the wall of the hole from caving in, to prevent movement of fluids from one formation to another and to aid in well control.
Industry:Oil & gas
drawworks, drilling line, and traveling and crown blocks. Auxiliary hoisting components include catheads, catshaft, and air hoist.
Industry:Oil & gas
the closing and sealing component on a blowout preventer. One of three types—blind, pipe, or shear—may be installed in several preventers mounted in a stack on top of the wellbore. Blind rams, when closed, form a seal on a hole that has no drill pipe in it; pipe rams, when closed, seal around the pipe; shear rams cut through drill pipe and then form a seal.
Industry:Oil & gas
a downhole tool, composed primarily of slips, a plug mandrel, and a rubber sealing element, that is run and set in casing to isolate a lower zone while an upper section is being tested or cemented.
Industry:Oil & gas
pertaining to a well in which production of oil has decreased and production of water has increased (for example, “the well has gone to water”).
