The results obtained in the article enable to draw a conclusion about the sufficient accuracy of assessing the energy state and the possibility of using an algorithm for the indirect determination of reservoir pressure for solving practical problems of geological exploration and geological recovery research in selecting and planning geological and engineering operations and monitoring the work of the base well stock. However, algorithms for indirect determination of reservoir pressure should not fully replace well testing but they can be considered as an additional tool for assessing the reservoir pressure and their results should be analyzed considering the experience of the reservoir development in specific geological conditions.
