Abstract

All over the world and in the Russian Federation, the problem of forecasting and exploration of new deposits at great depths is acute. In September 2009, the Tiber oil field was discovered in the Gulf of Mexico at a depth of more than 10 km. In Kazakhstan, within the framework of the Eurasia project, it is planned to drill an ultra‑deep well in the Pre‑Caspian depression. In this regard, a comparative analysis of the geodynamics and oil and gas potential of the Caspian Basin and the Gulf of Mexico, as well as the Caspian‑Caucasian and Caribbean‑Mexican regions, is of particular importance. The Pre ‑ Caspian depression and the Gulf of Mexico are the largest oil and gas provinces in the world. In the structure and geodynamics of structures, certain features of similarity are observed. The rise of hot asthenospheric diapirs determines the oil and gas content of sedimentary basins and the formation of large oil and gas fields. The solution of the problem of mechanical and mathematical modeling makes it possible to estimate the magnitude of the rise of the mantle diapir under the Pre‑Caspian depression.
