Method and apparatus for insulating a resonator downhole

Abstract

A method and apparatus are provided for insulating electrical connections to a resonator from fluid downhole under extreme pressure and temperature conditions downhole. The method and apparatus provide a pliable insulator that maintains electrical isolation between resonator electrical connections during exposure to high pressures downhole. The insulator is evacuated or placed in a vacuum prior to curing to remove bubbles from the insulator material. The insulator is then heat cured. The insulator is substantially chemically non reactive so that the insulator maintains electrical isolation between the resonator electrical connections during exposure to fluids downhole. The insulator has a thermal coefficient of expansion in a range so that the insulator maintains electrical isolation between the resonator electrical connections during exposure to high temperatures downhole.
