Monograph . Baku . Posts Tagged ‘Nafta-Press’ 2002. - 108 s. The key role of methane formation in the formation of phase and mechanical instability zones in the sediment shell . The formation of hydrocarbon deposits, manifestations of mud volcanism, the formation of specific folding are timed to certain stages of the evolution of hydrocarbon systems. These processes are reflected in the variability of geochemical and physical fields .. Suggested directions and methods for improving the technology of oil and gas exploration, based on the differentiation of sedimentary basins in terms of water exchange intensity, phase instability and mechanical instability From the editor.
