  • Drilling signals analysis for tricone bit condition

    2021-3-1 · Although assessing tricone bit wear condition using measurement while drilling (MWD) data can benefit the mining industry, researches have been limited by the complexities of conducting a comprehensive field study. MWD data analysis could cover a wide range of applications from blast fragmentation optimization to process fault detection. One approach in the literature to study bit wear relied on measuring energy consumption during drilling.

  • Ascent Uses At-Bit Data, Improves Drilling Efficiency

    Achieve consistent single bit runs while drilling with air. Ascent Resources wanted to achieve consistent single bit runs through a specific interval comprising 7,300 ft of interbedded shale, limestone, dolomite, and sandstone. The strategy was to identify those points in the interval prone to causing damage to 12 1/4-in TCI bits. Additionally, the interval would be drilled using compressed air rather than liquid mud for 90 to 100 drilling h.
