Full Description

his recommended practice provides standard procedures for determining the following characteristics of oil-based drilling fluids:

a)drilling fluid density (mud weight);
b)viscosity and gel strength;
c)filtration;
d)oil, water, and solids concentrations;
e)alkalinity, chloride concentration, and calcium concentration;
f)electrical stability;
g)lime and calcium concentrations, calcium chloride, and sodium chloride concentrations;
h)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 (Annex A);oil and water concentrations from cuttings (Annex B);drilling fluid activity (Annex C);aniline point (Annex D);lime, salinity, and solids concentration (Annex E);sampling, inspection and rejection (Annex F);rig-site sampling (Annex G);cuttings activity (Annex H);active sulfide (Annex I);calibration and verification of glassware, thermometers, viscometers, retort kit cups, and drilling fluid balances (Annex J);high-temperature/high-pressure filtration using the permeability-plugging apparatus (PPA) (Annex K);elastomer compatibility (Annex L);sand content of oil-based fluid (Annex M);identification and monitoring of weight-material sag (Annex N);oil-based drilling fluid test report form (Annex O).
