Includes all amendments and changes through Reaffirmation Notice , March 2016
Additional Comments: GX1318 * SAME AS ISO 10416
Published By:American Petroleum Institute (API)
This International Standard provides procedures for the laboratory testing of both drilling fluid materials and drilling fluid physical, chemical and performance properties. It is applicable to both water-based and oil-based drilling fluids, as well as the base or “make-up” fluid.
It is not applicable as a detailed manual on drilling fluid control procedures. Recommendations regarding agitation and testing temperature are presented because the agitation history and temperature have a profound effect on drilling fluid properties.
