Tension-set packers

Ensure effective and economical through-tubing restimulation with tension-set packers from Baker Hughes. The resettable packer enables precise, successive treatment of individual clusters by providing zonal isolation from above, while using specially designed fluid plugs or sand to isolate from below. With our tension-set packers, you get cost-effective restimulation to extend your well’s profitable production.

通过详细设计有针对性的治疗

For your restimulation applications, our experts work with you to design an optimal treatment program based on a thorough review of historical production data and analysis of the well’s production contribution profile. This ensures that restimulation treatments are targeted to those clusters that may have been untreated or undertreated during the initial stimulation.

流体速率和量进行预先修饰，然后在工作过程中实时监控，以确保骨折处理适当定时和交付。The packer’s enlarged tool inner diameter (ID) does not create flow restrictions when deployed with coiled tubing sizes up to 2-7⁄8 in. As a result, you can achieve high pump rates of high-concentration sand slurries for further stimulation effectiveness of individual zones.

包装器被部署在盘绕管（CT）上，并将其设置在要处理的群集上方，从而从上到下产生机械隔离。然后将刺激处理通过CT和包装器泵向下，并进入第一个群集。在重新填充工作期间，可以通过原始的穿孔将治疗泵入编队，从而通过消除专用的管道交流 - 过渡性运行来节省时间和金钱。

After treating the first zone, a precisely calculated fluid plug or sand diverter is pumped to isolate the wellbore area below the packer. With the wellbore effectively isolated, the packer is unset, moved uphole to the next cluster, and the process is repeated until all desired clusters have been treated. Once all fracture treatments are complete, the well is cleaned out with the coiled tubing in place. An unloader on top of the packer has ports designed to clean the area above the packer. An emergency release sub is also included to release and disengage the packer should the tool get stuck.

Thanks to its rugged, reliable design, you can set and unset the tension-set packer more than 60 times, ensuring precise and thorough wellbore coverage in a single trip. The packer’s ability to individually treat your targeted clusters reduces your fluid and hydraulic horsepower requirements by more than 30% compared to plug-and-perf completions.

Ultimately, our tension-set packer gives you a more targeted and environmentally responsible solution to extend the production of your unconventional wells while reducing your rig time and surface requirements.
