a transmitting element that provides a first signal to a ground formation;

a receiving element that receives energy from the first signal transmitted into the ground formation by the transmitting element, wherein the received energy is converted into a second signal that includes data that is provided to a computer such that the computer can perform an evaluation to identify a property of the ground formation;

a first contactless communication element located inside of a wellbore casing configured to receive the second signal based on a tuned operating frequency that is selected based on either or both a number of layers of the casing and a thickness of the casing;

a second contactless communication element located on an exterior surface of the wellbore casing that transmits the second signal at the tuned operating frequency to the first contactless communication element, wherein the second signal is transmitted through the casing at the operating frequency associated with the casing; and

a communication interface coupled to the first contactless communication element over which the data included in the second signal is sent to the computer.
