WebDec 3, 2024 · Electrical resistivity tomography (ERT) is a geophysical method used to image the subsurface using differences in measured electrical resistivity at the surface. These differences in resistivity can be tied to the porosity, fluid content, and degree of water content in the subsurface [1]. WebGeophysical constraints are imposed by calculating the EM forward data of the initial resistivity models followed by inversion of the EM forward data to obtain the final resistivity models. This allows us to create a comprehensive resistivity model database (RMD) that may not only improve performance and generalization but also incorporate ... ridgecrest by sureloc https://connersmachinery.com
