Abstract: Geoelectrochemical methods ( CHIM) have been greatly changed after decades of development. Traditional low?efficiency technology has been replaced by extremely efficient methods. This paper reviews the history of CHIM's development and summarizes the progress made in recent years. Principles and methods of "independent power dipole CHIM technique" are introduced. Furthermore, questions related to method's application promotion are discussed and expected, such as commercialization of technical devices, techni?cal system's standardization and mechanism of anomaly's formation.
