n: horizontal representation of elevations of a subsurface rock layer or structure.

n: a map of critical horizons - subsurface oil-producing zones-in a given area.

n: The fluid used to soak struck point and free struck after sticking .

n: drill pipe, drill collars, casing, or tubing that has inadvertently become immovable in the hole. Sticking may occur when drilling is in progress, when casing is being run in the hole. or when the drill pipe is being hoisted.

n: The portion of the drillstring that cannot be rotated or moved vertically.

refers to drill pipe stuck in the hole from differential sticking or bridging.

n: the depth in the hole at which the drill stem, tubing, or casing is stuck. Also called freeze point.

n: The point that drillstring be freezed.

n: The layer position of wellbore in there drillstring be sticked.

n: (nautical) an anchor chain on which each link has a bar, or stud, across the shorter dimension of the link to prevent kinking and deformation under load.

n: a device that prevents along a piston, rod, propeller shaft, or other moving part that passes through a hole in a cylinder or vessel. It consists of a box or chamber made by enlarging the hole and a gland containing compressed packing. On a well being artificially lifted by means of a sucker rod pump, the polished rod operates through a stuffing box, preventing escape of oil and diverting it into a side outlet to which is connected the flow line leading to the oil and gas separator or to the field storage tank. For a bottomhole pressure test, the wireIine goes through a stuffing box and lubricator, allowing the gauge to be raised and lowered against well pressure. The lubricator provides a pressure-tight grease seal in the stuffing box.

n: The sealing box used to seal off moving component.

a device using an elastomer seal (and sometime oil or grease injection) that provides a pressure barrier around a moving tubular or wireline.
