Patent number: 10280744Abstract: An acoustic transducer, such as a bender bar, having ferroelectric actuation elements that are designed to optimize a predetermined deflection mode shape. The acoustic transducers may include one or more rounded modally shaped actuation elements or weighted actuation elements. Modal shaping of the actuation elements allows for specific targeting of modes which most efficiently radiate acoustic energy.Type: GrantFiled: February 21, 2014Date of Patent: May 7, 2019Assignee: Halliburton Energy Services, Inc.Inventors: Michael L. Fripp, Paul G. Junghans, Chen Li, Batakrishna Mandal

Patent number: 9891336Abstract: The disclosure addresses multiple embodiments of an acoustic isolator, and an acoustic logging tool which incorporates the acoustic isolator. The acoustic isolator is configured to minimize acoustic transmissions which could otherwise adversely affect acoustical measurements being made by an acoustic receiver. The described acoustic isolators include a plurality of longitudinally arranged mass members coupled to a central supporting structure, in a configuration to reduce acoustic transmissions in at least selected frequency ranges.Type: GrantFiled: March 27, 2014Date of Patent: February 13, 2018Assignee: Halliburton Energy Services, Inc.Inventors: Chung Chang, Abbas Arian, Gary Kainer, Paul G. Junghans, Arthur Cheng, Randall Bennett Jones

Patent number: 7921913Abstract: An apparatus and method for protecting temperature sensitive components from the extreme temperatures a hydrocarbon producing wellbore. The apparatus comprises an inner housing encompassed by an exterior housing, where a plenum is formed between the two housings. A vacuum is formed within the plenum. The temperature sensitive components are stored within the inner housing. An aerogel composition is placed on the outer surface of the inner housing thereby providing added insulation for protecting the temperature sensitive component. Optionally the aerogel composition can be added to the inner surface of the outer housing. Yet further optionally, a reflective foil may be disposed over the aerogel composition of the inner housing.Type: GrantFiled: November 1, 2005Date of Patent: April 12, 2011Assignee: Baker Hughes IncorporatedInventors: Borislav J. Tchakarov, Paul G. Junghans

Patent number: 6484801Abstract: A universal joint between adjacent, electrically connected instrument housings for downhole well operations allow the connected housings to bend longitudinally as required to traverse an arced section of a well bore but does not permit relative elongation or twisting about the longitudinal axis of the housings. In one embodiment, a fluid impermeable open passage space at atmospheric pressure surrounds electrical signal carriers linking the instrument circuitry within the two housings. The passage is constructed as a high-pressure flexible bellows or as a braided or spiral wound high-pressure fluid hose. In another embodiment, a fluid impermeable sheath surrounds the signal carriers and encapsulates the signal carriers by a resilient solid. The articulation structure comprises a Cardan-type of universal joint wherein two fingers project longitudinally from the end of each of the housings.Type: GrantFiled: March 16, 2001Date of Patent: November 26, 2002Assignee: Baker Hughes IncorporatedInventors: James E. Brewer, Borislav Tchakarov, Paul G. Junghans, James C. Hunziker

Patent number: 5357481Abstract: A logging-tool assembly for generating both flexural wavefields and compressional wavefields in the sidewall formations encountered by a borehole. The assembly consists of a sonde constructed of a plurality of segments that are axially rotatable with respect to each other. Each one of two of the segments includes a compartment in which is mounted a dipole bender bar transmitting transducer. Two additional segments each contain one or more binaurally sensitive receiver transducers. Monopole transmitting and receiving transducers are also included in the respective appropriate segments. An acoustic isolator of novel construction acoustically separates the transmitting transducers from the receiving transducers.Type: GrantFiled: November 4, 1992Date of Patent: October 18, 1994Assignee: Western Atlas International, Inc.Inventors: Robert A. Lester, Paul G. Junghans, Donald J. Hilliker, Mathew G. Schmidt, Jose R. Casarsa, Gregory J. Wilkinson
