n: The drilling fluid filtrate reducer of amylum derivant that amylum reacts with alkyl sulfate in the alcaline condition.

n: The method that can measure drilling fluid filtration regulated by API. Refered to the filtrated volume of drilling fluid in the condition of routine pressure of 690kpa(+ or -35kpa),filter area of 4580mm2(+ or - 60mm2) and 30min.

n: a nonfermenting cellulose product used in drilling fluids to combat contamination from anhydrite (gypsum) and to lower the water loss of the mud.

n: A production manufactured by acetic acid chloride after plant fibre is alkalized. Usually used as filtrate reducer and adhesion promoter.

n: A kind of amylum derivant manufactured by amylum and acetic acid chloride. Usually used for filtrate reducer of drill fluid and improving heat proof capacity of drill fluid.

a natural starch used in drilling fluids.

n: A kind of quantitative analysis apparatus.Used for analysis of drill fluid and filtrate.

n: A kind of method measuring pH value of drilling fluid or filtrate.

n: The cutting is infiltrated by slight liquid and froth added into the air in gas drilling.

n: a log designed to provide the resistivity measurements necessary to estimate the effects of mud filtrate invasion into the formation surrounding the wellbore so that more reliable values for the the formation resistivity may be obtained. The resistivity curves on this log are made by deep-, medium-, and shallow-investigation induction. Visual Observation of the dual induction focused log can give valuable information regarding invasion, porosity, and hydrocarbon content. The three curves on the log can be used to correct for deep invasion and obtain a better value for formation resistivity. Compare induction survey.

n: the point marking the end of one stage of a process. In filtrate analysis, the endpoint is the point at which a particular result is achieved through titration.

n: 1. a fluid that has been passed through a filter. 2. the liquid portion of drilling mud that is forced into porous and permeable formations next to the borehole.

n: The liquid that is forced through a porous medium during the filtration process. See also fluid loss.

the liquid that leaks off into the formation during fluid loss.
