The value of the pressure on the bit multiply the rate of drilling in rotary drilling.

v: To stop drilling or production operations when it becomes unprofitable. A wildcat may be abandoned after poor results from a well test. Cement plugs are placed in the wellbore to prevent fluid migration between different zones.

a failure mode that can cause the cancellation-of or immediate-halt-to a project or event. Generally expressed as a percent probability.

(abs) adj: independent or unlimited, such as an absolute condition, or completely unadulterated, such as alcohol.

n: the force in dynes that a stationary flat plate with a surface area of 1 square centimetre exerts on a similar parallel plate 1 centimetre away and moving in its own plane with a velocity of 1 centimetre per second, the space between the plates being filled with the liquid in question. It is a measure of the resistance that the liquid offers to shear. absolute error n: the difference between the result of a measurement and the true value of the measured quantity as determined by means of a suitable standard device.

a filter rating that purports to set the maximum size of an opening in a filter or the maximum size of the particle that can pass through the filter. The definition varies with use and company.

n: the property by which a fluid in motion offers resistance to shear and flow. Usually expressed as newton seconds/metre.

the measure of a fluid’s ability to resist flow without regards to its density. It is defined as a fluid’s kinematic viscosity multiplied by its density.

n: a hypothetical temperature at which there is a total absence of heal Since heat is a result of energy caused by molecular motion, there is no motion of molecules with respect to each other at absolute zero.

zero point on the absolute temperature scale;equal to -273.16 degrees C, or 0 degrees K (Kelvin),or -459.69 degrees F, or 0 degrees R (Rankine).

abbr: altocumulus.

a precision sized micron particle material used for testing the solids stopping capability of filters.
