n: in a sucker rod pump, the device that contains and confines the valve ball and keeps it the proper operating distance from the valve seats.

n: A very important target. The lower the filter loss of drill fluid, the more steady the borehole face is.

n: The percentage of the volume of solid particle in cake and total volume of cake.

n: one of the alkaline earth elements with a valence of 2 and an atomic weight of about 40. Calcium compounds are a common cause of water hardness. Calcium is also a component of lime, gypsum, and limestone.

n: the active ingredient of slaked (hydrated) lime, and the main constituent in cement (when wet). Referred to as lime" in field terminology. Its symbol is Ca(OH)2

n: Ca(OH)2, white powder. The pH value of its saturated solution is 12.4. Usually used for depressant of inorganic salt, calcium mud and clearing excessive carbanion in drill fluid.

Ca(OH)2, slaked lime.

n: A component of rotary viscometer. Connected with inner barrel.

n: pulse per unit volume.

n: 1. a table that shows the capacities of, or volumes in, a tank for various liquid levels measured from the dip point or from the ullage reference point. Also called gauge or tank capacity table. 2. a table that is developed by recognised industry methods to represent volumes in each tank according to the liquid (image) or empty space (ullage) measured in the tank. Also called tank capacity table, tank table.

n: a record showing variations in wellbore diameter by depth, indicating undue enlargement due to caving in, washout, or other causes. The caliper log also reveals corrosion, scaling, or pitting inside tubular goods.

n: A tool run on wireline that measures the diameter of the wellbore. It may be used for detecting washouts, calculating cement volumes, or detecting internal corrosion of casing.

a recording of the diameter changes in a well made by a tool with mechanical arms that touch the wellbore or a sonic signal bouncing off the borehole wall.

n: Borehole diameter value of every well depth obtained from borehole diameter chart.
