Geophysical studies of the technical condition of wells

Our paper considers the problems arising during the monitoring of the technical condition of wells: determining the quality of cementing, identification of column defects and overflows, corrosion areas, evaluating the eccentricity of the columns. The main research areas and software systems in the field of geophysical control of the technical condition of wells, technical means of delivery of geophysical instruments and apparatus to the bottom of horizontal wells, some modern tools for monitoring well operation are characterized.
