METHOD FOR GEO-ELECTROCHEMICAL PREDICTION OF OIL AND GAS PRESENCE Russian patent published in 2011 - IPC G01V9/00

Abstract RU 2416115 C1

FIELD: physics.

SUBSTANCE: samples are collected on a defined network of profiles. Geochemical processes are activated in the samples using direct current of 100-150 mA for 20-50 min. Values of redox potential Eh_current and acid-base parametre ph_current in the cathode region are determined. Relative parametres Δc=ph_current/ph_initial and Δd= ph_current/ph_initial are calculated. Oil and gas presence of the investigated object is determined from the increase in the complex parametre defined as C_k=|Δc·Δd|.

EFFECT: high efficiency and accuracy of predicting oil and gas presence.
