n: The package of casing head, including air-proof component and gland, used to seal airtight tubing casing annulus.

tubes with a diameter slightly larger than the braded wireline or slick line that are used in the “stuffing box” on a wireline intervention to isolate the well pressure and fluid from the atmosphere. They work in combination with oil or wireline grease in

n: a device used to form a seal around a reciprocating or rotating rod (as in a pump) to prevent fluid leakage. Specifically, the movable part of a stuffing box by which the packing is compressed. See stuffing box.

a seal around a moving rod.

n: a pulley that is normally attached to the wellhead at a convenient place for the wireline to pass through as it comes from the stuffing box sheave before being spooled onto the wireline reel. The hay pulley prevents any lateral force from being exerted on the lubricator and the wellhead.

n: a solid pack of ice that covers more than half of the visible sea surface. packing n: a material used in a cylinder, in the stuffing box of a valve, or between flange joints to maintain a leak proof seal.

n: the metal part that compresses and holds packing in place in a stuffing box. See stuffing box.

n: the topmost portion of a string of sucker rods. It is used for lifting fluid by the rod-pumping method. It has a uniform diameter and is smoothly polished to seal pressure effectively in the stuffing box attached to the top of the well.

a surface rod pup joint that slides through the stuffing box on a beam pumped well. The part is highly polished and generally chrome plated. It must not be exposed to HCl acid.

n: a heavy-duty steel, T - shaped pipe fitting that is screwed or flanged to the top of a pumping well. The polished rod works through a stuffing box on top of the tee and in the run of the tee to operate a sucker rod pump in the well. Pumped fluid is discharged through the side opening of the tee.

a Tee fitting in the top of a rod pumped well. The side ort allows the pumped fluids to flow into the surface lines.

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.
