摘要：

Raman spectroscopy is used to estimate thermal maturity of shale samples collected from seven wells in the Najmah Formation in Kuwait, encompassing a range of maturities between 0.80 and 1.40%VRE. The Najmah Formation contains kerogen Type II-S (S/C > 0.04) and therefore, maturity correlations for Type II are not applicable due to differences in organic material structure, kinetics and thermal transformation pathways. A new correlation is proposed for the purpose of thermal maturity estimation in Type II-S kerogens. The presented correlation is able to predict the thermal maturity, based on Raman spectra, with good accuracy when compared to the reflectance-derived thermal maturity values.
