Currently, the ambiguity of the obtained results of petrophysical studies based on laboratory definitions and estimates of calculated parameters creates problems both with their justification and with the assessment of the reliability of the initial data, which is especially important when discovering and developing new deposits. The main feature of Cenomanian rocks is their weak cementation due to the conditions of rock formation. As a result of the analysis, the factors of reducing the reliability of the determination of filtration-capacitance properties were established and criteria for substantiating the assessment of the quality of the results of petrophysical studies were formulated. This made it possible to bring the results of laboratory data to a unified technology of petrophysical studies of the core represented by weakly cemented rocks. The reliability of the results obtained is confirmed by comparing the data of laboratory core studies with the results of interpretation of the data of geophysical well surveys, testing and hydrodynamic studies of wells.
