ISO 10414-2:2011

ISO 10414-2:2011 provides standard procedures for determining the following characteristics of oil-based drilling fluids:

       drilling fluid density (mud weight);
       viscosity and gel strength;
       filtration;
       oil, water and solids concentrations;
       alkalinity, chloride concentration and calcium concentration;
       electrical stability;
       lime and calcium concentrations, calcium chloride and sodium chloride concentrations;
       low-gravity solids and weighting material concentrations.

The annexes provide additional test methods or examples that can optionally be used for the determination of:

       shear strength
       oil and water concentrations from cuttings;
       drilling fluid activity;
       aniline point;
       lime, salinity and solids concentration;
       sampling, inspection and rejection;
       rig-site sampling;
       cuttings activity;
       active sulphides;
       calibration and verification of glassware, thermometers, viscometers, retort kit cups and drilling fluid balances;
       permeability plugging apparatus with set-screw secured end cap;
       permeability plugging apparatus with threaded end cap;
       elastomer compatibility;
       sand content of oil-based fluid;
       identification and monitoring of weight-material sag;
       oil-based drilling fluid test report form.
