The use of bicenter polycrystalline diamond compact (PDC) bit technology, dual-power-head down-hole motors, and oil-based drilling fluids helped save significant costs on a recent well drilled in the Gulf of Mexico. Not only has underreaming been eliminated, but the overall rate of penetration has been significantly increased. Directional control problems experienced during one phase of the well may limit use of the technique in difficult directional wells. This article discusses both the successes and the failures of this technique during the drilling of two phases of the same Gulf of Mexico well.
