Scope

This document specifies the principles, instruments, materials, experimental conditions, and the sampling and composition analysis steps required for testing the mineral composition using X-ray diffraction method, as well as the method and precision requirements for calculating shale brittleness index based on mineral composition.

This document is applicable to reservoir quality evaluation and sweet spot identification in shale gas production.
