Abstract
A formation measurement and processing technique which reduces the effects of standoff between a resistivity tool and a borehole wall where the resistivity tool utilizes capacitive coupling between the tool and the formation to obtain resistivity data useful to generate a resistivity image of the formation. Reduction of standoff effects is achieved through the use of multi-frequency, phase sensitive measurements to identify a measured resonance frequency that may be used to produce an image that utilizes measurements least affected by the tool standoff and unknown or unspecified inductance of the tool. Reduction of standoff effects are the most pronounced in the case of the low resistivity formations and oil-based, low-conductive drilling fluids.
