ISO/TC 67/SC 3/WG 3 - Well and formation treatment fluids

ISO 13503-6:2014 provides consistent methodology for measuring the fluid loss of completion fluids under dynamic conditions. ISO 13503-6:2014 is applicable to all completion fluids except those that react with porous media.

ISO 13503-2:2006 provides standard testing procedures for evaluating proppants used in hydraulic fracturing and gravel-packing operations. "Proppants" mentioned henceforth in ISO 13503-2:2006 refer to sand, ceramic media, resin-coated proppants, gravel-packing media and other materials used for hydraulic fracturing and gravel-packing operations. The objective of ISO 13503-2:2006 is to provide a consistent methodology for testing performed on hydraulic fracturing and/or gravel-packing proppants.

ISO 13503-4:2006 provides for consistent methodology to measure fluid loss of stimulation and gravelpack fluid under static conditions. However, the procedure in ISO 13503-4:2006 excludes fluids that react with porous media.

ISO 13503-5:2006 provides standard testing procedures for evaluating proppants used in hydraulic fracturing and gravel packing operations. ISO 13503-5:2006 provides a consistent methodology for testing performed on hydraulic fracturing and/or gravel packing proppants. The "proppants" mentioned henceforth in this part of ISO 13503-5:2006 refer to sand, ceramic media, resin-coated proppants, gravel packing media, and other materials used for hydraulic fracturing and gravel-packing operations. ISO 13503-5:2006 is not applicable for use in obtaining absolute values of proppant pack conductivities under downhole reservoir conditions.

ISO 13503-1:2003 provides consistent methodology for determining the viscosity of completion fluids used in the petroleum and natural gas industries. For certain cases, methods are also provided to determine the rheological properties of a fluid.
