Summary: | Methods and systems for determining a standoff between a downhole tool and a geological formation are provided. The standoff may be determined using a standoff measurement system that includes an electrode component, one or more electronics components, one or more transformers, and one or more processor units. When the standoff is expected to be no more than a first distance, a first measurement can be made where both originating and resulting electrical signals are induced at the electrode component. When the standoff is expected to be no less than a second distance, a second measurement can be made where an originating electrical signal is induced at one of the transformers while a resulting electrical signal is induced at the electrode component. |
