Abstract: Techniques for quantifying minerals in a formation sample include using a joint inversion of DRIFTS (diffuse reflectance infrared Fourier transform spectroscopy) spectra and XRF (X-ray fluorescence) data. This joint inversion produces quantification of additional minerals (e.g. pyrite and barite) than those quantified by the individual inversion method (DRIFTS-only). The method is applied to oilfield reservoir samples and the mineralogy solution is compared to the DRIFTS-only solution and to mineralogy estimated from benchmark FTIR (transmission Fourier transform infrared spectroscopy) method.
