  • Method for quantitative analysis of core samples
    Patent number: 4839516
    Abstract: A method for quantitative mineral analysis of core samples obtained from oil and gas wells is disclosed. The method includes the steps of grinding the sample to very small particle size and combining the sample with a carrier material such as KBr to form a pellet. The pellet is observed in a Fourier transform infra-red spectrometer and the resultant spectra compared with those of known standards in a digital computer to produce a quantitative analysis of the material.
