System and method for measuring downhole parameters

A method for measuring downhole parameters of an underground formation, the underground formation having a wellbore extending therethrough, the method comprising:

• deploying the downhole tool into the wellbore, the downhole tool comprising:
• a conductive tool body section;
• an electrically decoupling insulated tool body section mechanically coupled to the conductive tool body section;
• a conductive current return (CR) tool body section mechanically coupled to the electrically decoupling insulated tool body section, the conductive CR tool body section configured for direct contact with the formation;
• a pad mounted on the conductive tool body section, wherein the pad comprises:
• a conductive plate that injects current into the formation at a frequency in a range above 100 kHz and below 10 MHz;
• at least one button electrode that measures current injected into the formation;
• and
• a standoff spacer affixed to the conductive plate, the standoff spacer configured for direct contact with the formation;
• and
• extendable suspension means affixed to the conductive plate, that, when extended, cause direct contact between the standoff spacer and the formation;
• positioning the pad adjacent to the subterranean formation for electrically coupling thereto without direct contact therewith;
• passing an electrical signal I having a frequency in a range above 100 kHz and below 10 MHz into the subterranean formation;
• and
• measuring at least one downhole parameter of the formation from the electrical signal I at a location along the conductive CR tool body section electrically decoupled from the pad.
