n: a test that measures the reservoir pressure of the well, obtained at a specific depth or at the midpoint of the producing zone. A flowing bottomhole pressure test measures pressure while the well continues to flow;a shut-in bottomhole pressure test measures pressure after the well has been shut in for a specified period of time. See bottomhole pressure. bottomhole pressure gauge.

n: a bottomhole pressure test that measures pressure while the well is flowing. See bottomhole pressure test.

n: a combination of a potential test and a bottomhole pressure test the purpose of which is to determine the effects of different flow rates on the pressure within the producing zone of the well to establish physical characteristics of the reservoir and to detennine the maximum potential rate of flow. See bottomhole pressure test, potential test.

n: the average temperature within the reservoir, measured during logging, drill stem testing, or bottomhole pressure testing using a bottomhole temperature recorder.

n: a bottomhole pressure test that measures pressure after the well has been shut in for a specified period of time. See bottomhole pressure test.

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: a stuffing box and lubricator used with wireline during a bottomhole pressure test. See stuffing box.
