scope:

This part of ISO 10414 provides standard procedures for determining the following characteristics of water-based drilling fluids:

drilling fluid density (mud weight);

viscosity and gel strength;

filtration;

water, oil and solids contents;

sand content;

methylene blue capacity;

pH;

alkalinity and lime content;

chloride content;

total hardness as calcium.

Annexes A through K provide additional test methods which may be used for

- chemical analysis for calcium, magnesium, calcium sulfate, sulfide, carbonate and potassium;

- determination of shear strength;

- determination of resistivity;

- removal of air;

- drill-pipe corrosion monitoring;

- sampling, inspection and rejection;

- rig-site sampling;

- calibration and verification of glassware, thermometers, viscometers, retort-kit cup and drilling-fluid balances;

- permeability-plugging testing at high temperature and high pressure for two types of equipment;

- example of a report form for water-based drilling fluid.
