Abstract
A method for estimating characteristics of a formation including collecting a formation sample, preparing the sample, and analyzing the sample using FTIR comprising identifying the kerogen lineshape and intensity. The method includes using the lineshape to obtain kerogen maturity, using the maturity to obtain the kerogen spectrum, and using the kerogen spectrum to obtain the mineralogy and kerogen content.
