Abstract

The disclosure provides methods and systems for evaluating formation geometry and petrophysical properties directly from raw electromagnetic measurements. The methods involve using a downhole tool to measure a property of a formation at multiple depths of investigation and calculating geometry and petrophysical property information by direct inversion from raw measurements acquired by the tool. The system includes a tool for measuring a formation property at different depths of investigation and a processor for calculating geometry and petrophysical information by direct inversion from the raw measurements acquired by the tool.
