Pyrogenic Reservoir Rocks as a Factor of Geofluidodynamic Inhomogeneity

Doklady Earth Sciences - This article considers the Kansk–Achinsk brown coal basin. Huge reserves of solid organic matter (OM) are concentrated in the Jurassic sandy–clayey sediments;...     

The Coalfields of the Karst-Erosional Downcuttings of the Volga–Ural Oil and Gas Basin as a Factor of Geofluidodynamic Heterogeneity

Doklady Earth Sciences - This work considers the Early Carboniferous coal-bearing deposits of the karst-erosional paleo-downcuttings of the Volga–Ural oil and gas basin. The depth of their...     

The Role of Organic Matter in Formation of the Properties of a Shale Deposit

Doklady Earth Sciences - Baltic oil shales–kukersites were studied as an example of rocks with rock-forming organic matter (OM). The volumetric significance of their OM is shown (due to the...
