ABSTRACT:
A system for controlling the direction of a drill bit in a borehole utilizes both a drill string model and a bit-rock directional interaction model to compare ideal predicted or expected moments with real time measured moments to arrive at correction data necessary to return the bit to its desired path. The magnitude and direction of moments generated near the bit are measured in a downhole equipment sub, containing a microprocessor and memory, so that the real time data can be collected and acted upon without undue delay thereby minimizing drilling time lost due to deviations from the desired path.
