An entry of water, gas, oil, or other formation fluid into the wellbore during drilling. It occurs because the pressure exerted by the column of drilling fluid is not great enough to overcome the pressure exerted by the fluids in the formation drilled. If prompt action is not taken to control the kick, or kill the well, a blowout may occur.
Industry:Oil & gas
Oil, gas, water, or any combination that enters the borehole from a permeable formation.
Industry:Oil & gas
A record of the natural or induced radioactive characteristics of subsurface formations. Also called nuclear log. See radioactivity well logging.
Industry:Oil & gas
A sub that allows different sizes and types of drill pipe or other components to be joined.
Industry:Oil & gas
1. to bring a well into production; used most often when gas is injected into a gas lift well to start production. 2. in workover operations, to swab a well to restore it to production. 3. to deviate a wellbore from the vertical, as in directional drilling.
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
1. the crown block or top of a derrick or mast. 2. the top of a piston. 3. a high spot formed on a tool joint shoulder as the result of wobble.
Industry:Oil & gas
The depth in a vertical hole at which a deviated or slant hole is started; used in directional drilling.
Industry:Oil & gas
An assembly of sheaves or pulleys mounted on beams at the top of the derrick. The drilling line is run over the sheaves down to the hoisting drum.
Industry:Oil & gas
1. in drilling, to control a kick by taking suitable preventive measures (for example, to shut in the well with the blowout preventers, circulate the kick out, and increase the weight of the drilling mud). 2. in production, to stop a well from producing oil and gas so that reconditioning of the well can proceed.
