Paper presented at the 2018 SEG International Exposition and Annual Meeting, October 14–19, 2018
Paper Number: SEG-2018-2991051
..., the challenge is how to reduce the non-uniqueness in the inverted horizontal and vertical resistivities (? h and ? v ) since the typically reconstructed ? h and ? v models have conflicting depth structures, crossing major formational boundaries and hence difficult to explain in terms of subsurface geology...

... electric fields are related to the horizontal and vertical resistivities, respectively. In addition, the horizontal electric field is insensitive to thin, horizontal resistors associated with hydrocarbon reservoirs. Thus, the horizontal electric field contributes mainly to defining the horizontal...
