Abstract
Various embodiments include apparatus and methods to utilize signals acquired from a multi-component induction tool operating in a wellbore. The acquired signals can be correlated to an apparent conductivity of a formation and mapped to components of the apparent conductivity tensor conductivity. A multi-stage inversion scheme can be implemented to determine three-dimensional formation parameters from operating the multi-component induction tool. Additional apparatus, systems, and methods are disclosed.
