Recommended Practice for Field Testing Oil-Based Drilling Fluids
This 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.
