First settled the rapid assessment of complex geo-environmental and technological risks in exploration, refining and transportation of hydrocarbons in the northern Caspian Sea. Exploration and production of natural resources in the sea areas determines a significant impact on the environment, which makes performing offshore operations. Geological impacts shall mathematical modeling to reduce the factors and optimizing the use of marine resources. Scale accumulation, rock character and structure of deposits further complicate exploration in marine waters due to the presence of unconsolidated rock bottom. In the bottom sediments formed gas accumulation, representing technological risks. In the topography of the observed irregularities, increasing geo-ecological and technological risks on drilling rigs in geoologorazvedochnyh works. The spread of oil spills at sea have a fundamentally different character, different from the land. The greatest damage to oil spills deliver when contaminated beaches, so it is advisable to evaluate a risk of coast on the time to reach the coast of the oil spill. Atmospheric circulation caused by types of pressure systems in the atmosphere that affect the technology development of marine resources, the values of the dynamics of wind is the geological criteria.
