Hydrodynamic equations model mud-pulse telemetry transmissions

A closed-loop drilling system, to be effective, requires reliable two-way communication between the downhole module and surface.1 2Today's drilling industry uses mud-pressure pulse telemetry as one of the most popular and low-cost communication and data transmission methods between the surface and bottom of the wellbore.Maximizing the data communication rate and transmission distance for mud-pulse telemetry has become important problems for the industry.
