Solution
Once the plug selection and stage spacing were finalized in the completion program, Workover Solutions proposed using patented BitSavR technology, WOS-engineered an manufactured POWR Motors, and WOS-developed AV sub to accomplish the single-trip drill out. Taurex selected one of their patented premium line JZ completions bits to accomplish the single-trip drill out. These technologies paired with the PurpleSeal™ PS-C all composite frac plug created the optimal scenario to achieve an industry first – a single trip drill out of 262 frac plugs.
Results
The drill out consisted of using a Deep Well snubbing unit, patented WOS BitSavR technology, WOS-engineered and manufactured POWR Motors, and WOS-developed AV sub, and a Taurex JZ completion bit. The entire drill-out was completed in a single trip lasting approximately 6-1⁄2 days.
As result of a controlled WOB approach, no short trips and minimal motor stalls were reported. After the job, Taurex utilized their patented BitVision™ technology to verify that the bit maintained a 24% effective cutting structure with all cones and bearings intact. This project proved to be a tremendous success and was repeated three more times in the subsequent wells on the same pad totaling 261, 259 and 255 stages each.
