Patent number: 11946364Abstract: A method for removing a guided wave noise in a time-domain may include recording one or more acoustic signals with one or more receivers at a first location, wherein the one or more acoustic signals are raw data. The method may further include determining a slowness range, estimating a downward guided wave noise by stacking the one or more acoustic signals based at least in part on a positive slowness, estimating an upward guided wave noise by stacking the one or more acoustic signals based at least in part on a negative slowness, and identifying a dominant direction of propagation. The method may further include identifying a slowness from a highest stacked amplitude for the dominant direction of propagation, estimating a downward guided wave noise with the slowness, estimating an upward guided wave noise with the slowness, and subtracting the downward guided wave noise and the upward guided wave noise.Type: GrantFiled: July 7, 2020Date of Patent: April 2, 2024Assignee: Halliburton Energy Services, Inc.Inventors: Yao Ge, Ruijia Wang, Philip William Tracadas, Yi Yang Ang, Xiang Wu

Patent number: 10294772Abstract: An example apparatus for downhole cement inspection may include a tool body and an acoustic transmitter coupled to the tool body. An acoustic receiver may be coupled to the tool body at a first distance from the acoustic transmitter. A first array of acoustic receivers may be coupled to and positioned around a circumference of the tool body at a second distance from the acoustic transmitter. The second distance may be greater than the first distance. The acoustic receiver may be one receiver of a second array of acoustic receivers coupled to and positioned around the circumference of the tool body at the first distance. The first distance may be approximately three feet and the second distance may be approximately five feet.Type: GrantFiled: April 22, 2014Date of Patent: May 21, 2019Assignee: Halliburton Energy Services, Inc.Inventors: Jim T. Hill, Philip E. Fox, Arthur Chuen Hon Cheng, Philip William Tracadas

Patent number: 9158014Abstract: In some embodiments, an apparatus and a system, as well as a method and an article, may operate to rotate a rotatable driving member having at least one driving lobe, and to periodically contact at least one cam on a unitary driven member with the at least one driving lobe during rotation of the rotatable driving member, to set the driven member in motion. This motion can be used to launch an acoustic wave along an axis substantially orthogonal to the axis of rotation of the driving member, where the driving member disposed completely within the driven member. The signature of the acoustic wave can be at least partially determined by the profile of the cam and the rotation rate of the driving member. Additional apparatus, systems, and methods are disclosed.Type: GrantFiled: April 9, 2012Date of Patent: October 13, 2015Assignee: Halliburton Energy Services, Inc.Inventors: Clovis Bonavides, Batakrishna Mandal, Arthur Cheng, Wei Zhang, Philip William Tracadas, Gary Kainer, Hong Li Hou, Burkay Donderici
