... section of vertical and horizontal resistivity from 2.5D inversion. It is shown with a real data case from the North Sea that a 1000 m separation between the data points results in a poorly resolved overburden where the estimated resistivity structure is clearly not geologically consistent. This also...

.... A depth model was defined for both the overburden and the reservoir interval based on an available well log, and the data was inverted as a series of 1D inversions for all common mid-points along two survey lines to form 2D resistivity sections. Both the vertical and horizontal resistivities were inverted...
