ZondRes3D uses simple and clear data format allowing easily combine various systems of observation, including different variants of the topography setting up and other additional information. Convenient interface and variety of data visualization features allow solve wide range of geological problems with maximum effectiveness. ZondRes3D represents ready solution for electrical tomography, and solves wide range of problems from mathematical modeling and sensitivity analysis to field data processing and interpretation. The method of finite differences works approximately twice faster, but doesn’t allow use a topography. Two methods of solving forward and inverse problem of electric field calculation are realizes in the program - method of finite elements and method of finite differences. But in many cases for three- dimensional interpretation it is enough to use the results of two- dimensional electrical tomography received on several parallel profile lines.įeature of ZondRes3D program is its high resource using connected with specificity of the forward and inverse problem solution of big dimension that requires powerful computer. The technique of three- dimensional electrical tomography means a special measurement technique with use of a considerable number of switched electrodes (some electric prospecting cables) while number of measurements reaches ten thousand. Special equipment with programmed automatic switching of electrodes is applied for reaching of maximum effectiveness of field works. Their number usually reaches first thousand that is why the question on field measurements efficiency has basic importance and in many aspects defines possibility of practical using of this method.

Resolution and thus interpretation quality of electrical tomography is closely connected with the number and density of measurements on one site. It significantly extends the range of electric prospecting solved problems due to sections investigating that are considerably different from «classic» horizontal-layered.

For interpretation of electrical tomography data two- and three- dimensional models is used. Such approach allows from one hand to work with a modern high-performance instruments, and on the other hand to apply effective algorithms of modeling and inversion. Its feature is multiple reusing as a source and receiver just the same electrodes position, fixed on a site. ZondRes3D is designed for three-dimensional interpretation of electrical tomography resistivity and induced polarization data in land, cross-borehole and marine variants.Įlectrical tomography is a whole technique including the method of field observations and technology of processing and field data interpretation.
