API RP 13B-2

Die Annotation des Normtextes API RP 13B-2 :

This recommended practice provides standard procedures for determining the following characteristics of nonaqueous drilling fluids (NADFs):

• • drilling fluid density (mud weight);
• • viscosity and gel strength;
• • filtration;
• • nonaqueous fluid (NAF), water, and solids concentrations;
• • alkalinity, chloride concentration, and calcium concentration;
• • electrical stability (ES);
• • lime and calcium concentrations, calcium chloride, and sodium chloride concentrations;
• • low-gravity solids and weighting material concentrations;
• • sand content;
• • high-temperature, high-pressure (HTHP) filtration using the permeability plugging apparatus (PPA). See more
