More Information
Summary:A telemetry system, method and computer-readable recording medium are provided, the method including inducing a first pressure pulse in drilling fluid, which first pressure pulse has a leading pressure transition and a trailing pressure transition. Pressure variations are read at three or more locations, and the resulting pressure signals are used to determine a time between the leading and trailing pressure transitions.
