Patent number: 11466558Abstract: Logging of data by a downhole tool disposed in a borehole may be affected by tool wave effects. The tool waves appear in the first echo of casing wave arrivals and the amplitudes may be much larger than casing wave arrivals. The estimates of casing wave amplitude are biased due to these tool wave arrivals when using conventional cement-bond logging (CBL) processing. An automated adaptive inversion-based array processing for CBL evaluation using a downhole tool provides an improvement in the calculation of a bonding index.Type: GrantFiled: June 18, 2020Date of Patent: October 11, 2022Assignee: Halliburton Energy Services, Inc.Inventors: Ruijia Wang, Wei-Bin Ewe
