Using Inversion of Extra-deep Resistivity Data in High-angle Wells

The ability to look deeper around the well-bore using EM induction measurements is very beneficial for proactive geosteering and optimal well placement. A deeper reading tool leads to an increase in complexity of the data and models involved. Inversion becomes a necessity in resolving multi-layer formation parameters from multi-component LWD resistivity measurements. In this paper we consider the application of advanced inversion software to common tasks in geosteering and while drilling formation evaluation with an extra-deep resistivity tool. A field case study is presented.
