Patent number: 11965411Abstract: Implementations described and claimed herein provide systems and methods for isolation detection. In one implementation, an axial acoustic signal is obtained. The axial acoustic signal is captured using an axial sensor deployed in a structure in a subterranean surface. The axial acoustic signal is separated into a first wave region and a second wave region by applying velocity filtering. An axial symmetry of a portion of the structure is determined based on at least one of the first wave region or the second wave region.Type: GrantFiled: October 26, 2020Date of Patent: April 23, 2024Assignees: CONOCOPHILLIPS COMPANY, PIPELINES 2 DATA (P2D) LIMITEDInventors: Geoff Steel, Mark Walsh, Stephen John Mayo

Patent number: 11959377Abstract: Implementations described and claimed herein provide systems and methods for isolation detection. In one implementation, recorded data is obtained. The recorded data includes radial acoustic waves transmitted and received using a radial sensor of an acoustic logging tool deployed in a wellbore. Clockwise waves are separated from counterclockwise waves by converting the recorded data from a time domain to a frequency domain. The clockwise waves are shifted into shifted clockwise waves, and the counterclockwise waves are shifted into a shifted counterclockwise waves. A forward wave is generated by combining the shifted clockwise waves, and a reflected wave is generated by combining the shifted counterclockwise waves. One or more isolation regions are identified in the wellbore using the forward wave and the reflected wave.Type: GrantFiled: October 26, 2020Date of Patent: April 16, 2024Assignees: CONOCOPHILLIPS COMPANYInventors: Geoff Steel, Mark Walsh, Stephen John Mayo
