The results of the search and regional seismic surveys of the waters North-West of the Caspian sea identified a number of promising oil and gas structures on the forecasted recoverable resources are classified from small to large. This promising area is characterized by shallow, high jistotu the bottom of the swamps of the coast, which leads to the specifics of conducting a detailed seismic survey and application development technologies. The main objective in the early stages of engineering-geological surveys is the choice of the most favorable or less dangerous to embed the designed structures and communications. Such a task in the engineering-geological relation is solved by identifying, understanding and delineation of the components of the soil massif or places of processes, complicating the construction or negatively - the impacts to infrastructure and utilities during the period of their operation. In the big scope of engineering-geological surveys, carried out since 1997 part of project exploration works to ensure the safe production of Jack-up rig for the period of drilling exploration wells and for construction projects identified oil and gas fields, the peculiarities of the geological structure of the soil massif (Rootless Yu., Romanyuk B.F., et al., 2004) and defined the basic types of “geological hazards”, characteristic of the bottom of Northern Caspian sea.
