I am conducting resistivity survey since from 1975 for locating dug well and borewell points in Maharashtra .I have developed my own interpretation method which is so simple that there is no need to use the standard graphs. Moreover I am able to predict the strata as soon as my survey is over. My success rate is 90% for dugwell and 75% for borewell. My interpretation line is based on resistivity privciple. Now I want to write this interpretation guide lines so that it may prove helpful to others also. For this I want references to pioneer articles on resistivity theory.
Please guide me in locating the said references.
