A Permian Basin operator drilled a horizontal well and completed the toe section of the well with a traditional plug-and-perf completion method. The well was then flow tested, showing an elevated water cut that was higher than desired for the economics of the well. It was believed that excessive frac height achieved during the original hydraulic fracture treatment had breached into a nearby water zone. The operator reached out to Baker Hughes, a GE company (BHGE), for alternative completion methods, as it was imperative that the completion method enabled controlled frac height growth at economical costs.

After analyzing the well conditions, the BHGE team determined that the OptiStriker™ straddle packer system was the ideal solution. The OptiStriker system is the first of its kind, using two mechanically resettable packers to isolate individual clusters and precisely deliver controlled treatment volumes in unconventional wells. The system’s resettable packers—which can be run on coiled tubing or a workover rig—would allow the operator to stimulate five zones, using 10 stages, in a single trip.

The operator first deployed a plug to isolate the toe section of the lateral, and perforated all zones which were to be stimulated. The OptiStriker straddle packer system was then deployed on a workover rig to straddle each individual zone and perform an acid treatment, in order to assist with breakdown for the frac stages to come. Once all zones were acidized, each zone was then re-straddled and a proppant-laden hydraulic fracture treatment was performed. Compared to a typical packer and plug method, the OptiStriker system saved 20 trips, reducing NPT and costs by more than 50%, as well as greatly decreasing HSE risks. After the treatment, the system was retrieved from the well and no post-frac operations were needed. The well began producing immediately, avoiding NPT and excess costs.
