v: to bring a differential pen to the zero point on an orifice chart.

The point that its axial stress of drilling string equal to zero.

The filtration value of the crossing point of the direct ration relatio line and the filtration value line is called zero error.

There hasnt procuce free water after the slurry be made and motionless.

n: the output of a transducer with zero measurand applied.

n: on an orifice chart, the point at which no differential pressure is exerted on the differential pen.

a brand name of a tool used to deliver rapid impact stokes to a small BHA downhole. Operated by fluid flow. Usually run on CT.

n: electrokinetic potential of a particle as determined by its electrophoretic mobility. This electric potential causes colloidal particles to repel each other and stay in suspension.

It is a important index mark of measuring the stability of drilling fluid.

A acidic salt, ZnBr2, which is used to prepare dense, clear (solids-free) brine for well completion and workover operations. The density of saturated zinc bromide is approximately 20 lbm/gal, but its pH is low and can cause acidic corrosion and handling p

A neutral zinc salt, ZnCO3, which can be used as a sulfide scavenger in water-base muds. Zinc carbonate is less soluble than zinc basic carbonate and perhaps slower to react with sulfide ions. Treatment level is about 0.1 lbm/bbl per 50 mg/L sulfide ion (
