Abstract
The application of infrared and thermal analysis methods for identification
of clay minerals in petroleum reservoir rocks of Naharkatia
oil field has been investigated. Thermal analysis provided little infor·
mation regarding the nature of clay minerals unless most of the
heavier non-clay materials of the reservoir rocks were separated.
Clay minerals in the reservoir rocks without separation of the non·
clay materials could however be identified by the infrared technique.
Both thermal and infrared analysis revealed presence of illite and
chlorite type clay minerals in Barail reservoir rocks of Naharkatia
oil field. The findings were confirmed by X-ray powder diffraction
method.
