Latest Patents

Akito Shigekane holds a patent for an "Apparatus for monopole and multipole sonic logging of a downhole formation." This tool includes an acoustic source section, an acoustic receiver section, and an isolator section disposed therebetween. The design features a mandrel with integrally formed alternating first portions and second portions, allowing the tool to function acoustically as a mass and spring system. The isolator section effectively mutes or delays extensional and flexural modes intrinsic to the logging tool itself, minimizing the effects of the tool's presence on measurements. Additionally, the acoustic receiver section is equipped with axially oriented grooves for receiving an acoustic receiver module that includes a sensor, an amplifier, an A/D converter, and a digital multiplexer.
