n: The gas-holder tank connected with discharge line of reciprocal pump. It is a air cushion aerated by compressive air, used to absorb or decrease fluctuation of pressure and delivery capacity disproportion when reciprocal pump works.

ring compound materials in the oil composed of carbon, hydrogen, sulfur, nickel and other trace materials. Asphaltenes are mostly very small platelets (35 A) suspended by micelles of maltenes and resins and carried through the oil. They precipitate by agg

a clay or other mineral that was formed within the pore spaces of the rock. The material is most often formed by reaction or precipitation from connate fluids.

BASO4 scale is produced in the well and in facilities as the result of precipitation when incompatible waters (one having Ba ion and the other SO4 ion) are mixed or when the equilibrium of the flowing fluid reduced and a precipitate is triggered by over s

n: a machine designed specifically for sucker rod pumping. An engine or motor (prime mover) is mounted on the unit to power a rotating crank. The crank moves a horizontal member (walking beam) up and down to produce reciprocating motion. This reciprocating motion operates the pump. Compare pump jack.

movement of casing up and down to help remove mud and replace it with cement slurry.

n: I. the crystallisation or precipitation of soluble minerals in the pore spaces between clastic particles, causing them to become consolidated into sedimentary rock. 2. precipitation of a binding material around grains or minerals in rocks.

the material in the rock between the grains that binds the grains together.

a chemical that can tie up the molecules of an element, such as iron, and keep it in solution past the point where it should naturally precipitate.

sediment formed by precipitation from water, e.g., salt from dehydration and scales.

n: a rock of precipitated silica whose crystalline structure is not easily discemible and that fractures conchoidally (like glass). Flint, jasper, and chat are forms of chert.

a hard, silicate sedimentary rock. Similar to flint, but with less ordered structure. A cryptocrystalline form of quartz.
