Our Track Record Speaks for Itself

Repeat Precision drilled out 262 PurpleSeal™ PS-C composite frac plugs in 154 hours with impeccable isolation.

Challenge

In Pennsylvania’s Marcellus Basin, a major operator drilled a three-mile lateral constructed with 6” 24# production casing measuring 23,938 ft (MD) and a lateral length of 15,672 ft. The greatest challenge that completions teams face when dealing with long lateral sections is the plug drill-out. The plug selection for this situation was critical for obtaining a clean and effortless drill-out.

An equally important aspect of an operation this extreme is protecting vital bit, sub and motor components to ensure the BHA can withstand the harsh trip through 262 composite frac plugs. To make the project that much more challenging, the operator, Repeat Precision, Taurex Drill Bits, and Workover Solutions devised a plan that would lead to an operational first in the completions space: a single-trip drill-out of 262 frac plugs.

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. Taurex selected one of their patented premium line JZ completions bits. These technologies, paired with the PurpleSeal™ composite frac plug, created the optimal scenario to achieve our goal of a single-trip drill-out.

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 6.5 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.
