Abstract
The use of electrochemical effects in petroleum exploration and engineering-geological applications is discussed with reference to the Zhirnovsky oil and gas field where mobile forms of metals are 1.5-2 times above the background. Electrochemical stiffening applied to Maastrichtian shales, which are sliding planes of landslides in the Lower Volga area, increased their stiffness by a factor of 2 or more.
