Dynamic Paleotectonic Analysis as a Method for Localizing Inversion Zones in the Sedimentary Cover

Dynamic paleotectonic analysis (DPA) was developed to study the direction (uplift/subsidence) and amplitude of movements affecting target horizons with potential for oil and gas traps. The primary objective of DPA is to identify zones of tectonic inversion – movements that trigger the formation of faults or zones of heightened mobility, which in turn facilitate the creation of hydrocarbon traps. Quantitatively assessing the dynamics of movement direction (uplift/subsidence) and amplitude allows for the identification of tectonic inversion zones within the sedimentary cover. In addition to traditional paleotectonic analysis, the DPA method enables a quantitative assessment of the geological evolution of the sedimentary cover. It helps to determine the geological epochs during which movement directions and amplitudes shifted and allows for the localization of tectonic inversion zones. Ultimately, this increases the probability of identifying areas likely to contain non-anticlinal hydrocarbon traps. In this work, the possibilities of supplementing qualitative analysis with a quantitative study algorithm are demonstrated using actual examples, allowing for the formalization of stages of paleotectonic evolution of the sedimentary cover and the numerical justification of the amplitudes and directions of tectonic movements.
