Popis: The relevance of the research. In recent years, there have been significant changes in the territorial distribution of oil and gas reserves and resources in Perm region. At present, all large and medium-sized oil and gas deposits have been explored in the territory of the platform part of Perm region. At the same time within the Solikamsk petroleum district of the Volga-Ural petroleum province the possibility of opening such deposits actually exists, especially in pool outline of the Verkhnekamsky field of potassium and magnesium salts. Selection of objects and determination of their order of entry into prospecting and appraisal drilling play an important role for successful geological exploration works. The main aim of the article is to identify the priority objects for setting up prospecting and appraisal drilling based on statistical models of oil and gas forecasts. Object: lead and prepared oil and gas structures of the Solikamsk petroleum district of the Volga-Ural petroleum province located in pool outline of the Verkhnekamsky field of potassium and magnesium salts. Methods: development of multidimensional models by the method of recursive regression analysis. Results. For a comprehensive ranking of all available structures located on the territory of the Verkhnekamsky field of potassium and magnesium salts, a complex zonal-local criterion of oil and gas content – RnKOMP – was calculated. The impact of morphological (Pukvmorf), migration (Pkm), geochemical (Pukvgh) parameters and gas events data criterion (PnMNX) on the integrated PnKOMP indicator was evaluated. From the analysis of the constructed models, it follows that the criteria of Pukvmorf, Pukvgh are more universal, while Pkm, PnMNX are manifested only for the choice, which includes the structures with the highest values ​​of the complex indicator PnKOMP. The most perspective objects were selected for input into prospecting and appraisal drilling.
