The 31/2-in-OD, 9.2-lbm/ft3 tubing was built with 25Cr material, which is significantly more challenging to cut than carbon steel. Because of the slot cutter’s versatility, seven drive sections were conveyed, providing seven cutting sections and multiple cuts along the BHA to minimize the number of runs. The phasing (90° orientation) between cutter assemblies also provided a high distribution of cuts across the perimeter of the tubing to enable a more effective stimulation treatment. As a result, only three runs were required to cut 275 slots precisely spaced across 130 ft, optimizing cutting efficiency.
The ReSOLVE iX service instrumentation and real-time surface readout enabled cutting precision and quality control. The job planning addressed all key risks such as debris management, slot positioning confirmation, vertical slot distribution, tight restrictions, and HSE risks. Additionally, a remote team of technical experts was able to provide continuous monitoring support for the field crew and shore-based customers due to the real-time transmission of downhole performance data supplied by the tool throughout the operation.
