Abstract: A downhole tool includes a receive antenna configured to receive a signal from a surrounding formation, and a receive amplifier proximate to and coupled to the receive antenna. The receive amplifier is configured to provide an amplified signal responsive to the signal received by the receive antenna. The downhole tool also includes an electronics carrier, including receive circuitry, coupled to the receive amplifier by a conductor. The electronics carrier is positioned axially away from the receive antenna and the receive amplifier, and the receive circuitry is configured to receive and process the amplified signal.

Abstract: A connector ring comprising a body extending along a longitudinal axis and two sets of sensor connectors. The first set of sensor connectors comprises one or more transmitter sensor connectors coupled with the body and extending parallel to the longitudinal axis, the one or more transmitter sensor connectors having a first end. The second set of sensor connectors comprises one or more receiver sensor connectors coupled with the body and extending parallel to the longitudinal axis, the one or more receiver sensor connectors having a first end. The first end of the transmitter sensor connectors and the first end of the receiver sensor connectors are staggered along the longitudinal axis.

Abstract: A transducer, method, and downhole tool for acoustic logging. The acoustic transducer comprises a piezoelectric material comprising a body and grooves formed on the body. The grooves comprise a first groove that intersects with a second groove on the body. The method of acoustic logging a wall comprises transmitting an acoustic pulse at the wall using the acoustic transducer. The method also comprises generating a signal indicative of a reflection of the pulse using the acoustic transducer; and determining an acoustic parameter based on the signal using a processor. The acoustic logging tool is locatable in a wellbore intersecting a subterranean earth formation. The acoustic logging tool comprises the acoustic transducer and a processor configured to determine an acoustic parameter based on a signal generated by the acoustic transducer, the signal being indicative of the acoustic wave.

Abstract: A method and system for enhancing the signal quality of received signals generated by acoustic tools by factoring in feedbacks from the rig operations in an adaptive optimization process. The system may include a transmitter driver circuit and transmitters which can implement signal transmission at selected power, mode and waveforms. The selected power, mode and transmit waveforms may further be generated in the system by making optimal calculations based on realtime information from the downhole data regarding the formation and borehole characteristics.
