n: an oilwell that has come in with such great pressure that the oil jets out of the well like a geyser. In reality, a gusher is a blowout and is extremely wasteful of reservoir fluids and drive energy. In the early days of the oil industry, gushers were common and many times were the only indication that a large reservoir of oil and gas had been struck. See blowout.

n: an uncontrolled release of oil from the wellbore at surface.

a well drilled into a high pressure formation that results in an immediate surge towards the surface. In the days of cable tools with minimum fluid (hydrostatic) head, the formation fluids often flowed to surface when the pay zone was penetrated.

n: a surveying device that provides a series of photographic discs showing the inclination and direction of the wellbore.it measures direction by means of a gyroscopic compass.

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

n: a device used to detem1ine direction and angle at which a wellbore is drifting off the vertical. Unlike magnetic surveying instruments, a gyroscopic instrument reads true direction and is not affected by magnetic irregularities that may be caused by casing or other ferrous metals. See directional drilling, directional survey.

n: a kind of inclinometer used to measure the angle of inclination ,angle of orientation using the orientation-keeping ability of the top

n: the matallic screen mesh on which zinc is plated ,the wellbore size is 3.175mm,6.350,12.70mm

n: the partial or complete collapse of the walls of a hole resulting from internal pressures due primarily to swelling from hydration or formation gas pressures. See caving.

n: the partial or complete collapse of the walls of a hole resulting from internal pressure due primarily to swelling from hydration or formation gas pressure. See also sloughing.

partial or full collapse of the wellbore by particles of shale.

very high temperature perforation charge explosive;hexanitrostilbene.

n: the technological process in which makes the degree of inclination and azimuth steady according the design requirement of wellbore during directional drilling

n: in drilling operations, the wellbore or borehole. See borehole, wellbore.

n: refer todrill hole

n: the alternation of any point on wellbore
