    Abstract: A tool for monopole and multipole sonic logging includes an acoustic source section, an acoustic receiver section, and an isolator section disposed therebetween. The tool may include a mandrel having integrally formed alternating first portions having a first outer diameter and second portions having a second outer diameter. The second outer diameter is smaller than the first outer diameter, which allows the portions to function acoustically as a mass and spring system. The isolator section sufficiently mutes or delays extensional and flexural modes intrinsic to the logging tool itself. Thus, the effects of the tool presence on the measurements are minimized. In addition, a plurality of axially oriented grooves are defined in an outer surface of the acoustic receiver section, and each groove is configured for receiving an acoustic receiver module that includes a sensor, an amplifier, an A/D converter, and a digital multiplexer.

    Abstract: A seal assembly and an apparatus including the same are provided. The seal assembly may include a seal member with axially opposing sides and one or two back-up rings for substantially supporting at least one side of the seal member. The seal member may be made of elastomer and have an axially extending base with one or two flange portions and a protrusion extending perpendicularly from the base. The back-up ring may be made of a plastic material and a portion of the back-up ring may abut a radially outer surface of the flange portion of the seal member.

    Abstract: Acoustic isolators are disclosed herein. An example apparatus includes a transmitter to transmit an acoustic signal. The example apparatus also includes an acoustic isolator substantially surrounding a receiver, and the receiver is to receive the acoustic signal via an opening in the acoustic isolator. The transmitter and the acoustic isolator are coupled to a base. The acoustic isolator includes a first layer coupled to a second layer defining a plurality of spaces. The second layer is to provide an acoustic impedance mismatch.
