RT Journal Article SR Electronic(1) A1 VAN DAM, J. C.YR 1965 T1 A SIMPLE METHOD FOR THE CALCULATION OF STANDARD‐GRAPHS TO BE USED IN GEO ELECTRICAL PROSPECTING* JF Geophysical Prospecting, VO 13 IS 1 SP 37 OP 65 DO https://doi.org/10.1111/j.1365-2478.1965.tb01922.x PB European Association of Geoscientists & Engineers, SN 1365-2478, AB ABSTRACT The paper describes a new method for the calculation of standard‐graphs i.e. resistivity‐curves for assumed resistivity profiles. It starts from the integral of Stefanesco and arrives at a system of image poles, similar to, but simpler than earlier developed systems. The advantages of the new method are described, the accuracy is discussed and it is indicated how the accuracy can be improved by a simple artifice., UL https://www.earthdoc.org/content/journals/10.1111/j.1365-2478.1965.tb01922.x
