A signal transmission system including a first transducer mounted to a surface of a member, a second transducer movable into contact with a second surface of the member, a material disposed between the second transducer and the second surface of the member. A method for communicating acoustic energy through a member including pressing a second transducer to a second surface of the member, the member having a first transducer mounted to an opposite surface thereof, sandwiching a material between the second transducer and the second surface of the member, and transmitting a signal between the first transducer and the second transducer.

Signal transmission system and method

A method of controllably disintegrating a downhole article comprises disposing a first article in a downhole environment, the first article being the downhole article to be disintegrated; disposing a second article in the downhole environment after the first article is disposed, the second article carrying a device, a chemical, or a combination comprising at least one of the foregoing; and disintegrating the first article with the device, chemical, or the combination comprising at least one of the foregoing from the second article.

Downhole tools and methods of controllably disintegrating the tools

A method and apparatus for locating a collar of a casing of a wellbore is disclosed. A sensor for measuring a magnetic field is conveyed through the casing on a tool string. A physical model is formed of a process of obtaining a magnetic measurement of the casing with the sensor. A simulation of the physical model is run through a processor to select a design parameter of the tool that allows for using the sensor at a determined value of an operational parameter for obtaining the measurement at a selected signal-to-noise ratio. The tool is conveyed into the wellbore and the sensor set to the determined value of the operational parameter. The magnetic measurement of the casing is obtained using the sensor, and the collar is located using the obtained magnetic measurement.
