Northern part of the Caspian Sea is one of the perspective regions capable to increase the oil and gas capacity of the Russian Federation now. At the same time, conducting exploration works on the water area of the Caspian Sea is integrated to a number of difficulties of natural and ecological nature. Sea exploration works on oil and gas represent a difficult complex of geological and geophysical, engineering-geological and ecological researches, including drilling and approbation of wells. Exploration works in a northern part of the Caspian Sea are performed in difficult natural and geological conditions, have the tough ecological restrictions caused by direct proximity of especially protected natural territories, availability of valuable bioresources and features of the hydrological mode of the sea. With respect thereto, an urgent task is the choice of optimum complexes of researches for all stages of exploration works which would consider the difficult natural and geological conditions existing in this region and ensured an industrial and ecological safety of sea prospecting process.
