n: a device that regulates various factors (such as flow rate, pressure, or temperature) of a system without supervision or operation by personnel. See instrumentation.

n: automatic, self-regulating control of equipment, systems, or processes. See instrumentation.

n: a metering instrumentation system component mat counts me revolutions of me index shaft.

v: to detect, locate, and correct malfunctions in a computer, instrumentation, or other type of system.

n: a device or assembly of devices designed for one or more of the following functions: to measure operating variables (such as pressure, temperature, rate of flow, and speed of rotation);to indicate these phenomena with visible or audible signals;to record them;to control them within a predetermined range;and to stop operations if the control fails. Simple instrumentation might consist of an indicating pressure gauge only. In a completely automatic system, desired ranges of pressure, temperature, and so on are predetermined and preset.

n: an exploration method in which an instrument that measures the intensity of the natural magnetic forces existing in the earths subsurface is passed over the surface or through the water. The instrumentation detects deviations in magnetic forces, and such deviations may indicate the existence of underground formations that favour the entrapment of hydrocarbons.

n: an employee of a mud logging company who performs mud logging. mud logging n: the recording of information derived from examination and analysis of formation cuttings made by the bit and of mud circulated out of the hole. A portion of the mud is diverted through a gasdetecting device. Cuttings brought up by the mud are examined under ultraviolet light to detect the presence of oil or gas. Mud logging is often carried out in a portable laboratory set up at the well.

n: the staff that responsible for collecting and analysising the material of mud and debrics.

the person who monitors the mud for hydrocarbon shows, y use of chemical analysis, microscopic examination or instrumentation.

n: see instrumented pig.

a pigging device that incorporates instrumentation to measure properties of the pipe (corrosion, wear, etc.).

n: a velocity-measuring device for fluids in which the flow is parallel to the rotor axis and the speed of rotation is proportional to the rate of flow. The volume of gas in gas measurement is determined by counting the revolutions of the rotor. In liquid turbine meter measurement, the meter and electronic instrumentation are combined to measure total flow and/or flow rate within the piping system.
