Abstract:
A method for communicating a signal to an instrument in a wellbore includes axially accelerating the instrument in a preselected pattern of acceleration. The predetermined pattern corresponds to the signal to be communicated. The axial acceleration of the instrument is detected, and the signal is decoded from the detected axial acceleration. A signal detection system for an instrument in a wellbore includes an accelerometer oriented along a longitudinal axis of the instrument and means for comparing measurements made by the accelerometer to at least one predetermined pattern.
