Resistivity Imager in Non-Conductive Mud for LWD and Wireline Applications

摘要

An apparatus, method and computer-readable medium for imaging an earth formation. A downhole assembly having a resistivity sensor is conveyed in a borehole penetrating the earth formation. The resistivity sensor includes a plurality of antenna coils arranged along a radial line that is substantially perpendicular to a longitudinal axis of the downhole assembly and configured to obtain measurements of a resistivity property of the earth formation. A processor images the earth formation using the obtained measurements.
