Abstract (English):
The method of calculating the current density distribution over the depth of casing, based on materials 153-39.0-531-07 GD is proposed . An example of calculating the current density distribution over the depth for well casing № 22505 of Oil and Gas Production Department " Bavlyneft" JSC "Tatneft" is shown. The presence of anodic areas on the surface of the production casing are identified .
