Drilling fluids – Best Practices

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.

Gel Strength

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 . . .
