TORPEDO frac plugs and optimized milling service cut plug drillout time in half
An operator working in the Eagle Ford play in south Texas had drilled and cased two wells and was planning to fracture them using the plug-and-perf style completion method. Looking to reduce costs, the operator contacted Baker Hughes, a GE company (BHGE) about combining the latest frac plug technology with proven milling expertise.
BHGE recommended deploying its new TORPEDO™ composite frac plugs to divert treatments, and then using its through-tubing milling service to rapidly drill out the plugs. The proposed milling bottomhole assembly (BHA) included a 4½-in. tricone rock bit, a 33 /8-in. VIP workover motor, and a 33 /8-in. Hydropull extended-reach tool.
The TORPEDO plug, which features a shorter, more compact design with only a single set of slips versus the traditional two sets, significantly reduces millout time compared with conventional plugs. It is also robust and impact resistant, enabling increased run-in speeds with reduced preset risk. And with hundreds of thousands of frac plugs milled to-date—including TORPEDO plug millouts in basins across the US—the BHGE through-tubing team was confident it could deliver a fast, single-trip millout on this job.
Eager to explore all possible efficiency gains, the operator agreed to deploy the new plugs in both wells and to allow the BHGE through-tubing milling service team to drill them out. A total of 26 TORPEDO plugs were run in each well and set at regular intervals across the 6,700-ft (2,042-m) laterals. The operator and the BHGE team monitored parameters at surface throughout fracturing operations and pressure signatures confirmed successful treatment diversion
