The aim of the work was to study the effectiveness and reliability of the interpolation methods of the Petrel 2013 software complex with different data density in the study of bitumen deposits on the territory of the Republic of Tatarstan. The article is based on data obtained from a comprehensive study of the Western (171 wells) and Eastern (61 wells) uplifts, including data from field geophysics and laboratory core research. Cross-validation was carried out using five interpolation methods from the standard Petrel 2013 set for reservoir thickness values. The following methods were used to build the models: Indicator kriging (IK), Sequential indicator simulation (SIS), Sequential indicator simulation (Gslib) (SIS (Gslib)), Truncated Gaussian simulation (TGS-GRFS), and Truncated Gaussian simulation (TGS-SGS). The results obtained made it possible to draw the following conclusion: the core selection methods and interpretation of the field geophysics data have a significant influence on the reliability of interpolation models.
