Abstract
A method of and system for optimizing bit rate of penetration while drilling substantially continuously determine an optimum control variable value necessary to achieve an optimum bit rate of penetration based upon measured conditions and maintains control variable value at the optimum control variable value. As measured conditions change while drilling, the method updates the determination of optimum control variable value.
