PROXIMITY METHOD OF ELECTRIC PROFILING Russian patent published in 1998 - IPC

FIELD: geophysics, field operations for search for reservoirs filled with hydrocarbons, for other mineral resources, geological mapping, engineering and geological investigations. SUBSTANCE: proximity method of electric profiling includes profiling by way of successive turn and taking measurements with the aid of plant having two excitation and two measurement electrodes as minimum. With turn plant is additionally moved along Archimedean spirals. In this case length of plant, parameters of spirals and distance between measurement points on each of them is set equal to terms of series L_r= L_r-1+L_r-2, where r= 3,4, . ..; L₁= G=G; L₂=2G and G is base of series. EFFECT: enhanced authenticity of proximity method. 2 dwg
