ABSTRACT:
A system, apparatus and method for adaptive communication with a downhole device is disclosed. The instant invention proposes an adaptive system of communicating information from the surface of the earth to a device located downhole; thereby optimizing the drilling process by adaptively fitting the talkdown protocol around the existing drillstring RPM. A further economic benefit is that with this adaptive system the ΔRPM Offset between the optimized drilling condition and the RPM required for data transmission can be monitored and adjusted in real-time, resulting in less disruption to the drilling process. Several embodiments are given.
