Abstract: An acoustic telemetry transmitter includes transducer means having internal capacitance coupled with charging means, and switch means arranged to be switched by signals that are dependent upon control signals derived from sensor means and to produce a step response drive signal to the transducer means. The internal capacitance of the transducer means is used as an energy store in the production of a transmission output signal from the transducer means.

Abstract: A gauge hanger 10 and a setting tool 12 are disclosed. The setting tool 12 includes an electro-mechanical impact driver 26 and a drive shaft 28 which extends out of an outer casing 12. The gauge hanger 10 comprises a nut 32 which can be engaged by the drive shaft 28. When the nut 32 is rotated it can draw a threaded mandrel 36 upwardly in a wellbore. This causes the grippers 40 in a linkage assembly to be driven radially outwardly so that they can grip the sides of the wellbore. A pin 52 is designed to shear once the grippers have engaged with the sides of the wellbore so that the setting tool 12 can be lifted clear.

Abstract: Acoustic telemetry system including a transducer 60 and switching means 80. The internal capacitance of the transducer is used as an energy store in the production of an output signal. The transducer is coupled to a charging means 25. The switching means 80 is controlled using switch signals 24 which are dependant on signals from a sensor. The output signal may be pulse position modulation PPM. The transducer may be a piezoelectric ceramic transducer which can be connected in series with a tuning coil. The sensor may measure temperature or pressure. A transmitter and receiver of the system may be arranged remotely from one another along a tubular structure.
