n: That part of the wellbores trajectory where the drift angle is increasing.

n: The trajectory of borehole axis.

n:1. intentional deviation of a wellbore from the vertical. Although well bores are normally drilled vertically, it is sometimes necessary or advantageous to drill at an angle from the vertical. Controlled directional drilling makes it possible to reach subsurface areas laterally remote from the point where the bit enters the earth. It often involves the use of deflection tools. 2. a technique of river crossing in pipeline construction in which the pipe is buried under the riverbed at very much greater than those of conventional crossings. With this technique, a hole in the form of an inverted arc is drilled beneath the river, and the made-up pipeline is pulled through it.

n: The intentional deviation of a wellbore in order to reach an objective some distance from the rig.

drilling the wellbore in a planned angle of deviation or trajectory.

n: That part of the wells trajectory where the drift angle is decreasing (i.e. returning to vertical)

a survey of a wellbore that measures its position and trajectory.

n: a business organization that is hired by an operator to measure a wells trajectory. The company takes complete surveys of the hole, usually either before or after setting a string of casing or upon completion of the hole. This type of surveying program is separate from, and independent of, the directional supervisors surveys.

n: the path of the wellbore.
