n: a European term for datum plate. dip rod n: a rigid length of wood or metal that is provided with a scale for measurement and usually graduated in units of volume. It is used for manual measurement of liquid in a container. Also called dipstick.

the vertical displacement of a fault along the dip plane.

n: Schlumberger wireline tool that records shear, compressional and stoneley waveforms. Used for amplitude variation with offset (AVO) calibration, shear seismic correlation, wellbore stability measurements, sanding analysis, fracture height estimation and s

n: used in emulsion treating to heat noncorrosive emulsions that are under comparatively low pressure. Types are tubular, fluid-jacket, internal firebox, and volume, or jug-type. Compare indirect heater.

n: a device on a diesel engines governor that increases the engines speed by increasing positive voltage going to the actuator and governor. As the engine needs more fuel to go faster, the direct-acting actuator increases positive voltage to make the governor increase the fuel flowing to the fuel injectors. See electrically actuated governor:

n: commonly called a V-G meter: A rotational device powered by means of an electric motor or handcrank. Used to determine the apparent viscosity, plastic viscosity, yield point, and gel strengths of drilling fluids.

n: A kind of swivelling appliance which can measure kinds of rheological parameter of drilling fluid.

n: a device for measuring the viscosity of a fluid (a fluids resistance to flow) that provides a value for the viscosity on the device. No calculations have to be made since the device gives a direct reading of the value.
