1 Scope
This part of ISO 10414 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 sulphides (Annex I);
-
— calibration and verification of glassware, thermometers, viscometers, retort kit cups and drilling fluid balances (Annex J);
-
— permeability plugging apparatus with set-screw secured end cap (Annex K);
-
— permeability plugging apparatus with threaded end cap (Annex L);
-
— elastomer compatibility (Annex M);
-
— sand content of oil-based fluid (Annex N);
-
— identification and monitoring of weight-material sag (Annex O);
-
— oil-based drilling fluid test report form (Annex P).
