Abstract
Summary
Resolution power of a field 3D DC dataset is examined by gradually reducing the data density by removing selected transmitters from the dataset. A mineralized target zone with known geometry and resistivity is used to compare the inversion results for each subset. The results indicate that a high density measurements are essential in retrieving accurate geometry of the target. True 3D grid distribution provides an omni-directional dataset in which the subsurface is sampled by measurements having many different orientations.
