One of the priorities in oil and gas industry is determining quality of chemical agents used in well drilling, completion, operation, workover, production stimulation, and enhanced oil recovery processes. Use of chemicals in oil production processes is a global trend and an integral part of the present-day strategy of improving oil and gas field development efficiency. Advanced use of chemicals for oil production stimulation is now focused on synthesis and development of composite chemical systems. In addition to conventional inorganic acids, more complex components are used with increasing frequency, such as organic acids, chelate compounds, as well as a series of chemical agents to control acid-rock reaction kinetics and to selectively react with specific lithological components of reservoir rock and to change (control) structure and viscosity parameters. Considering these domestic and global trends, the importance of research in the field of testing and ranking composite acid systems based on specific geologic and physical field conditions is beyond dispute. Modern innovative approaches stipulate the necessity and importance of digitizing and ranking physical and chemical properties of chemical products in order to effectively and scientifically select chemical agents for targeted and efficient production stimulation operations.

The paper discusses the procedure of identifying the most viable acid system formulations for various productive formations based on rank differentiation of formulations according to their physical and chemical parameters.
