The importance of the choice of well exploitation methods is analyzed. Mechanical methods applicable in carbonate reservoirs are discussed. To maintain the efficiency of field development, it is important to maintain the productivity of wells at the planned level throughout the entire production period by increasing their productivity. Productivity increase, skin effect reduction is achieved with the help of acid treatment, the main principle of which is rock dissolution to form a man-made network of microchannels in the bottomhole formation zone, which allows maintaining the recovery rate at the planned level for a long period of time. Forecasting the flow rate of wells in fields with reserves of high-viscosity oil is one of the most difficult tasks in the development of oil fields. Acid treatments quality increasing through new working agent’s usage and improving the technology analysis is performed. Acidizing a reservoir is inherently dual in nature in terms of the desired effect: while in some conditions it has a positive effect, in other conditions it may not be applicable at all.

Complex system research of the interaction of structural components in nitrate systems of rare-earth and IA, IIA elements ofthe periodic system – precursors of modern multicomponent oxide polyfunctional materials on their basis – established theformation of a class of lanthanides alkaline coordination nitrates. The obtained data are the basis for identifying, controllingthe formed phases in the preparatory stages of processing in innovative technologies using nitrate predecessors of differentelectronic structures elements and various combinational methods of their activation, establishing technological andfunctional dependencies, controlling the modification of the synthesis products properties.
