n: The physicist A. E. Boycott found that the blood cell deposits faster when test tube deflects, especially 40°-50°, than when test tube is vertical. The same situation will be found in the drilling fluid in the horizontal well. That is why people call this

n: Small drilling rig for coring.

n: see drilling and delay rental clause.

The value of the pressure on the bit multiply the rate of drilling in rotary drilling.

n: the US Department of the Interior, Minerals Management Service rules and regulations that must be followed by those who drill and produce oil and gas wells located in the Outer Continental Shelf.

n: 1. a derrick or crane shaped like the letter A and used to handle heavy loads. 2. an A-shaped openwork structure that is the stationary and supporting component of the mast of a jackknife rig and to which the mast is anchored when it is in an upright or drilling position. 3. the uppermost section of a standard derrick, shaped like the letter A and used as a support in lifting objects such as the crown block to the water table.

v: to cease producing oil and gas from a well when it becomes unprofitable or to cease further work on a newly drilled well when it proves not to contain profitable quantities of oil or gas. Several steps are involved: part of the casing may be removed and salvaged;one or more cement plugs are placed in the borehole to prevent migration of fluids between the different formations penetrated by the borehole;and the well is abandoned. In most oil-producing states, it is necessary to secure permission from official agencies before a well may be abandoned.

to cease efforts to produce or inject fluids in a wells and to plug the well sufficiently to protect the environment and the ability to redrill and develop other reserves at a later date.

v: To stop drilling or production operations when it becomes unprofitable. A wildcat may be abandoned after poor results from a well test. Cement plugs are placed in the wellbore to prevent fluid migration between different zones.
