Refining hydrocarbon reserve location using modern geodynamics

Abstract

The paper considers some aspects of the theoretical prerequisites for the influence of geodynamic processes on the distribution of hydrocarbon accumulations in natural megareservoirs. The most interesting part to study is the part of Central Siberia, where quite a lot of large and unique oil and gas fields have been discovered in a relatively small area. It is shown that hydrocarbon deposits in the study area are organized into groups according to the size of reserves. This can be explained by geodynamic processes occurring during the geological history of the region. The features of the river network pattern are interpreted as local geodynamic settings of the «pushed block» type. The relationship between the parameters of local geodynamic settings and the scale of oil and gas accumulation is noted. Keywords: geodynamic processes; large and unique reserves; natural mega-reservoirs; geodynamic conditions; scale of oil and gas accumulation.
