An innovation technology of marine shelf oil or gas geoelectrical prospecting
© Lisin A.S.
A new electric technology of marine shelf oil or gas prospecting is presented. A movable orthogonal noise stable electric
sounding setup and differential - normalized method of sounding and electric current focusing at the point of the observation is
used. The technology provides hydrocarbon electric search at the marine depths up to 250-300 m due to anomalies of
electric resistivity, induced-polarization (IP) coefficient and time decay constant of IP electric potential in the vicinity of oil/gas
deposits. Mathematic simulation of electric sounding results on the Northwestern zone of the Black Sea shelf has been carried out. It
was shown that using the new technology one can search oil/gas deposits at the geological depths up to 2000 m.
