Annotation:
The authors of the article consider the results of processing and interpreting hydrodynamic and geophysical studies of wells carried out to assess the improvement of the filtration characteristics of the bottomhole formation zone using wave action technology. Based on the studied information, the strengths and weaknesses of the geophysical approaches under consideration were identified. The data analysis showed that the technical and forecast-evaluation stages of preparation before applying methods to enhance oil recovery are of great importance. High-quality selection of candidate wells allows getting a positive effect of the work. Otherwise, the lack of information on the technical state of the well and the absence of reliable operational parameters can lead to the inexpediency of operations to increase the productivity of production and injection facilities of development. Based on the results of the study, recommendations are proposed for the selection of candidate wells to successfully implement methods for treating the bottomhole zone and the conditions of conducting geophysical measures to obtain objective information before and after the work.
