Bibliography

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.
