Abstract: The present research is devoted to the substantiation of ecological methods of calculating the dynamic reservoir pressure to build maps isobars used in environmental analysis of field development in the North Caspian shelf. In the ecological process of developing offshore fields with horizontal long-haul wells is necessary to analyze the physical properties of the fluid, temperature and pressure in the reservoir, the productivity of wells and their mutual influence and especially, moving Oil-Water Contact (OWC). For the calculation values of pressure near wells, pressure gradients on the area of the field and are built in these areas of isobar maps with which average dynamic reservoir pressure can be defined. For operational control of the processes occurring in the reservoir and regulation of mining is conducted monthly calculation of dynamic formation pressure formula S. Joshi based on filtration characteristics and physical properties of the fluid hydrodynamic studies and variables measured parameters, fished in the well: the flow rate of the well and the bottom hole pressure. This type of work in the development of the field is necessary for analysis of the energy state of sediments, so need regular work to refine the mathematical model of production wells in Northern Caspian fields.
