Oilfield

A mechanical device attached to tool strings or flush surface tubulars as they are assembled or disassembled. The safety clamp prevents the tool string from being dropped downhole accidentally if the ...

Pitot tube

Oil & gas; Oilfield

A measuring device for determining the gas-flow rate. It is composed of a 1/8-inch tube inserted horizontally along the axis of the gas flowline. The pressure at the end of the tube is compared with ...

reservoir height

Oil & gas; Oilfield

A measurement of the vertical thickness of reservoir formation that is open to flow. The reservoir height is used in calculations and mathematical models to assess reservoir performance or potential ...

gamma-gamma log

Oil & gas; Oilfield

A measurement that uses a source of gamma rays and a detector of gamma rays. The term is synonymous with density log, and is just an older name.

propagation resistivity

Oil & gas; Oilfield

A measurements-while-drilling log of formation resistivity. The log normally contains at least one attenuation and one phase-shift resistivity reading. In many cases there will be multiple curves of ...

nuclear magnetic resonance measurement

Oil & gas; Oilfield

A measurement of the nuclear magnetic resonance (NMR) properties of hydrogen in the formation. There are two phases to the measurement: polarization and acquisition. First, the hydrogen atoms are ...

pulsed neutron spectroscopy measurement

Oil & gas; Oilfield

A measurement of the spectrum of gamma rays emitted by a formation bombarded by high-energy neutrons. Neutrons are emitted by a high-energy neutron generator (14. 1 MeV). The neutrons interact with ...
