Measurement while drilling tools were used to monitor and adjust downhole torque, which resulted in faster drilling and longer bit life. Polycrystalline diamond compact (PDC) bits have changed drilling strategies in the sand shale sequences of the Gulf of Mexico, increasing both rate of penetration and bit run lengths, and decreasing drilling costs, particularly in directional wells. While these important results have been achieved using the best drilling information available, little attention has been paid to downhole operating conditions since this information was unavailable during realtime drilling operations. In an effort to learn what benefits could be realized through applying MWD drilling technology to directional drilling with PDC bits, Tenneco teamed up with Anadrill Schlumberger for MWD downhole drilling measurements, and Diamant Boart Stratabit with their PD-11 series bits, to see what could be gained by the close cooperation of these three parties in drilling a typical offshore well. The result was a well drilled on target and under budget, and a new record bit run.
