Drilling fluids - Best Practices
This article presents some tips for running drilling fluid systems.
PV and YP
For optimum hydraulic parameters the values of PV and YP should be as low as hole cleaning efficiency and suspension of solids will allow. Low viscosities result in turbulent flow at any given pump rate.
A ‘ten minute’ gel strength of 25 lbs/100 ft2 shall be considered the absolute maximum for all muds under all conditions.
ECD should be kept to a minimum at all times. At laminar flow the frictional pressure . . .
