Applications in the Petroleum industry

Clay mineralogy
•  Kaolin polytypes;. low-high crystallinity, halloysite, dickite

•  Illite polytypes; distinguish 1M and 2M types, to help identify authigenic/detrital origin
•  Fe:Mg ratio of chlorites; to identify clinochlore or chamosite
•  Ammonium content in illites; an indicator of hydrocarbon migration and organic maturity  
•  Illite/smectite ratios; gives information on temperature history
•  Smectite discrimination; identify Fe, Mg and Al types

•  Total Clay Content

Stratigraphic logging
•  Variations in mineral distribution can improve well to well correlation through better definition of sedimentary sequences.

Carbonate identification
•  Differentiate dolomite, calcite, aragonite and siderite.

Well site mineralogy studies
•  Mineral logging of cuttings in near real-time.

Formation damage assessment
•  Identify scale, drilling mud invasion, reactive minerals.

Hydrocarbon detection

•  Identify and characterise hydrocarbon type - to indicate conditions of deposition and thermal maturity.

Facies mapping
•  Identify subtle changes in facies
•  Discriminate provenance of reservoir sands

Hydrates

•  Map hydrate signatures in new and old core

Fracture infill

•  Determine the infill mineralogy for improved permeability estimation
