Formula

d = [ (log ( R / (60 × N) ) / log ( (12 × W) / (1000 × D) ) ] × ( Pn / Pm )c Where, d = d-exponent value R = Penetration Rate N = Rotary Speed W = Weight on Bit D = Drill Bit Diameter Pn = Mud Weight Equivalent Pm = Mud Weight Used C = Shale Compactibility Coefficient

Use this simple online D Exponent calculator to detect transition from normal pressure to abnormal pressure.
