The operator aimed to drill a 12¼-in section in the Central North Sea within the agreed AFE. However, they had previously encountered significant challenges due to the section's risks of erratic torque, shock and vibration, stick-slip, downhole tool failures, and premature drill bit wear. These issues would likely require multiple drill bits and BHA runs. In addition, the planned section length had never been drilled in a single run within the field before, and the operator was dissatisfied with previous 12¼?in sections because each required multiple bit runs, which increased both operating time and costs.
糖心传媒 deployed the EnduroBlade 360 bit with the rotating cutting edge to successfully drill a total of 5,092 ft from the shoe to TD in a single run. Renowned for its wear resistance, this technology was supported by the DBOS system and IDEAS platform, which helped provide a comprehensive drillers’ roadmap. The roadmap leveraged finite element analysis and rock mechanics data to model cutting structures, optimizing operating parameters and removing guesswork. As a result, the operator reduced rig time by a minimum of 10 days compared with the drilling of previous sections.
