Abstract
A pressure release encoding system for communicating downhole information through a wellbore to a surface location has a valve for providing a fluid restriction to fluid passing in the wellbore, a sensor positioned in the wellbore for sensing a downhole condition in the wellbore, an actuator cooperative with the valve for moving the valve between at least two positions in timed relation to the downhole condition sensed by the sensor, and a detector positioned at the surface location for providing a measurement value at the surface location correlative to the time between the changes of the pressure of the fluid in the wellbore. The sensor is an inclination sensor for sensing an angle of inclination of a drill bit in the wellbore.
