Petroleum and natural gas industries. Completion fluids and materials - Procedures for measuring the long term conductivity of proppants Ingestion-build-224916 BS ISO 11231:2019 includes some1 Scope This part of ISO 13503 provides standard testing procedures for evaluating proppants used in hydraulic fracturing and gravel packing operations. NOTE The proppants mentioned henceforth in this part of ISO 13503 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 this part of ISO 13503 is to provide consistent methodology
