Today, most drilling efficiency decisions are based on models describing downhole drilling conditions. The inputs to these models have in the past been a collection of surface measurements. Measurements While Drilling (MWD) provides realtime information from near the bit and allows for a more comprehensive understanding of downhole drilling conditions. Downhole measurements can help eliminate uncertainties in the behavior of the drilling system, and provide a more scientific approach to improving drilling efficiency. The downhole drilling measurements include: weight on bit and torque measured by strain gauges set in a drill collar; temperature measured by a sensor on the outside of the collar; and mud flow rate interpreted from the MWD alternator output. Comparison of these measurements with surface data reveals previously unexpected trends that can help diagnose problems. The interrelationships among these measurements lead to a better understanding of the drilling process, and can help make immediate decisions concerning drillstring washouts, bit balling, packed off drilling assemblies, severe dog legs, the overloading of polycrystalline diamond compact bits, and the pulling of worn bits, resulting in direct savings of rig time.
