Abstract
A downhole tool for subsurface disposal is provided. The tool comprises an elongated tool body, an enclosure attached to an exterior surface of the tool body. The enclosure comprises at least one transducer disposed at an angle with respect to a longitudinal axis of the enclosure, and an electronics board coupled to and disposed adjacent to the at least one transducer. The enclosure also defines an internal cavity, and the internal cavity contains a fluid for insulating the at least one transducer from a downhole environment. The fluid is in direct contact with the at least one transducer and the electronics board.

A downhole tool for subsurface disposal, comprising:
- an elongated tool body;
- an enclosure attached to an exterior surface of the tool body;
- the enclosure comprising:
- at least one transducer disposed at an angle with respect to a longitudinal axis of the enclosure;
- and
- an electronics board coupled to and disposed adjacent to the at least one transducer;
- wherein the enclosure defines an internal cavity, and the internal cavity contains a fluid for insulating the at least one transducer from a downhole environment, and further wherein the fluid is in direct contact with the at least one transducer and the electronics board.
A method for packaging a transducer for subsurface disposal, comprising:
- attaching an enclosure to an exterior surface of an elongated body of a downhole tool, wherein the enclosure defines an internal cavity;
- disposing the transducer within the enclosure at an angle with respect to a longitudinal axis of the enclosure;
- disposing an electronics board within the enclosure adjacent to the transducer;
- coupling the electronics board to the transducer;
- and
- filling the internal cavity of the enclosure with a fluid to surround the transducer so that the fluid is in direct contact with and insulates the at least one transducer from a downhole environment.
