SURFACE LOGGING WITH CUTTINGS-BASED ROCK PETROPHYSICS ANALYSIS

摘要

Drilling process methods and systems for drilling are described. The methods include performing a drilling operation through a downhole formation, the drilling operation generating drilling cuttings. A single drilling cuttings sample is obtained at a surface-based location. X-ray diffraction (XRD) and/or x-ray fluorescence (XRF) analysis are performed on the single drilling cuttings sample. Element information and mineral information of the single drilling cuttings sample is obtained from the XRF analysis regarding the downhole formation. From the obtained information, a determination of at least one rock petrophysics property of the downhole formation is made.
