Abstract
In some aspects, systems and methods are provided for determining formation properties using data from both a high-frequency dielectric tool (HFDT) and an array induction tool (AIT). The system includes a controller in communication with at least one HFDT, at least one ART (which may be a multi-component AIT), and a processing unit. The acquired ART formation data can be processed and used to set constraints on the processing of the acquired HFDT formation data. In aspects, a set of processed HFDT data can be used to reinitialize the ART data processing, to allow for a repeated or iterative evaluation process. The system and method generate values used to determine one or more formation properties such as a resistivity of the formation, the presence of an invasion in the formation, mud resistivity or permittivity, anisotropy characteristics of the formation, and dipping characteristics of the formation.
