Apparatus and method for wellbore resistivity measurements in oil-based muds using capacitive coupling

A resistivity device for downhole use with a nonconducting mud injects a current at a frequency sufficiently high to pass capacitively through the mud and a mud cake into the formation. The frequency is further selected so that the impedance due to the dielectric constant of the formation is small c...
