Kolchugin A.N., Korolev E.A., Morozov V.P., Eskin A.A., Khasanova N.M. Structural Differences in Calcite in Lower Pennsylvanian Carbonate Oil Reservoirs of the Volga-Ural Region, Russia, Revealed by Electron Paramagnetic Resonance and Cathodoluminescence Microscopy / Advances in Devonian, Carboniferous and Permian Research: Stratigraphy, Environments, Climate and Resources, 2018. P. 360-366.

Annotation

This paper reports on the structural and geochemical differences in diagenetic calcites from oilwatercontacts determined by various methods. The differences in calcites were revealed by electron paramagnetic resonance (EPR) spectroscopy on the basis of the ratio of sulfur-oxygen radiation centers and impurity of manganese ions. The data obtained correlate well with the results of the analysis of extracted calcite grains divided using cathodoluminescence microscopy. A relationship was established between important diagenetic events in the basin history, and calcite structural features were established. Content of manganese Mn2+ in the lattice of calcite and the color of luminescence allow parameters of the oxidation-reduction potential of the calcite precipitation to be evaluated. According to EPR studies, there is a steady increase in the proportion of Mn2+ from the early stages of diagenesis to changes in rocks associated with oil migration and oil charge events, including time of
