Self potential method
WebWe have developed a comprehensive methodology for the acquisition and processing of self-potential (SP) data, as well as some keys for the interpretation of the results. The wide applicability of the SP method and its low cost make it a popular method to use in a variety of natural environments. WebAs self-potentials do not depend on any definite physical property but are due to differences in chemical activity in the ground, they give no clue (at least at present) about any distinct …

More recently it has been adapted for hydrogeological and water engineering applications, by the use of more sensitive equipment and the careful application of data correction processes.
WebThe Induced Polarization (IP) and Self-Potential (SP) methods measure electrical potentials from subsurface charges. In the time-domain IP method, a current is applied between two non-polarizable electrodes. When the current is abruptly turned off, the voltage drops quickly to a small residual value, then decays more slowly. WebSP is called also spontaneous polarization and is a naturally occurring potential. difference between points in the ground. SP depends on small potentials or. voltages being naturally produced by some massive ores. It associate with sulphide and some other types of ores. It works strongly on. pyrite, pyrrohotite, chalcopyrite, graphite.
WebMay 1, 2014 · The self-potential method has been used since 1920 as a complementary application in the exploration of metal deposits. Certain conditions, such as fluid flow, chemical reaction and temperature gradient, may lead to a change of the self-potential field of the ground, which forms anomalies different from the ambient self-potential field. ...
