Abstract
A mud pulse telemetry system is presented for transmitting information from the bottom of a well hole to the surface. The mud pulse telemeter is a pilot operated valve which restricts the flow of mud in the drill string to set up pressure waves in the mud stream which can be detected at the surface. The pilot operated mud pulse telemeter uses a small input signal to operate the telemeter valve by pressure differentials created in the mud stream itself.
