... resistivity. This results in separation of the phase-shift and attenuation resistivity curves. The curve separation can then be used to derive estimates of horizontal and vertical resistivities (Rh and Rv) of the formation. In well A, computer modeling was done to derive Rh and Rv, which were in turn used...

... Usually the quantitative resistivity curve derived from the central button of the EM1 tool requires further normal- ization to a standard resistivity log, for example, an SG. LLs, or DFL log. The reason for such normalization is related to residual errors associated with the nonlinearity of the electronic...
