Abstract
Background. Optimization of the development of residual oil reserves and procedures aimed at in creasing well productivity represents a principal task of subsoil exploitation. Within the Volga–Ural oil and gas province and adjacent oil-bearing zones, acid treatment technologies are among the most common methods for processing the bottomhole reservoir area. However, the existing tools used in the design and planning of these operations neglect several factors that affect their effect iveness, which imposes certain limitations. Aim. To develop a methodology for increasing the effectiveness of computer simulation of acid treatment technologies applied under the conditions of heterogeneous carbonate reservoirs of the Tournaisian stage of the Volga–Ural oil and gas province. Materials and methods. Generalization of the results of operation of more than 100 wells for various purposes using standard approaches for processing and interpreting of geological and field data. Results. Empirical formulas for calculating the duration of reservoir cleaning after treatment, volumes of the highly productive area of wells, and the effectiveness of acid treatments in these areas are presented.
