n: a single unit that acts as an oil and gas separator, an oil heater, and an oil- and water-treating vessel. See heatertreater.

n: the pipelines and other equipment needed to transport oil, gas, or both from wells to the gathering station. An oil gathering system includes oil and gas separators, emulsion treaters, gathering tanks, aIxI similar equipment A gas gad}ering system includes regulators, compressors, dehydrators, and associated equipment.

n: a vessel that heats an emulsion and removes water and gas from the oil to raise it to a quality acceptable for a pipe- line or other means of transport. A heater- treater is a combination of a heater, free- water knockout, and oil and gas separator.

n: a metal device used to remove small droplets of moisture or condensable hydrocarbons from a gas stream in an oil and gas separator. The small droplets of moisture collect on the metal surface to form larger drops, which are removed from the separator along with other separated liquids.

n: an item of production equipment used to separate liquid components of the well fluid from gaseous elements. Separators are either vertical or horizontal and either cylindrical or spherical. Separation is accomplished principally by gravity, the heavier liquids falling to the bottom and the gas rising to the top. A float valve or other liquid-level control regulates the level of oil in the bottom of the separator.

n: a cylindrical or spherical vessel used to isolate the components in mixed streams of fluids. See oil and gas separator.

a production treating vessel designed to facilitate the separation of gas, oil, and/or water from a produced fluid stream

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.

n: an oil and gas separator that is used to separate relatively small quantities of oil and gas, which are diverted through the testing devices on a lease.

a smaller separator than the main production separator, used for regular production tests to measure oil, gas and water rates on a well.

n: in well testing, an assembly of equipment that is attached to the wellhead of the well to be tested. The main component of a well test surface package is an oil and gas separator.
