High-frequency real-time drilling data from wired drill pipe has provided new insights on bottomhole assembly (BHA) dynamics in the New Mexico Delaware Basin. An enhanced understanding of downhole dynamics, formation characteristics, and their impact on bit and tool life has enabled the operator to optimize performance and achieve further improvements. Through these efforts, drilling time in a particular hole section has been reduced by 25%. The timesavings, combined with a reduction in trips and tool damage, has resulted in a 33% reduction in cost per foot. The real-time downhole data provided increased understanding of the occurrence and mitigation of common drilling dysfunctions such as torsional vibration, whirl, axial vibration, motor micro-stalls, and pipe buckling. Both the data explaining downhole performance and the successful practices that resulted from analysis of the downhole data are discussed in this paper. The data and results included in this paper contribute to the improved performance of the industry in this area of high activity and are useful for other areas with similar drilling practices.
