Most dissolvable frac plugs are made up of many different components, and these components are designed to dissolve at different rate, in order to survive pump down, last through the frac job, and reduce intervention time. Dissolution customization is necessary, but it can also limit the application range of these “tailor made” products.
WIZARD® ZERO Large-bore Dissolvable Collet is designed to eliminate customization and reduce tool complexity. The core component (as shown in the video) is a single piece collet that is designed to improve robustness and work under most well conditions, providing anchor and isolation of the casing ID. The nose cap and dart will quickly dissolve after frac job, revealing the collet’s huge ID for flow back. Inside a 5.5” 20# casing, the collet’s ID can expand up to 3.14” after setting.
It was field proven in multiple shale play regions, eliminating intervention beyond coiled tubing safety range. Its huge ID prevent sand and debris from packing up, allowing the operator to flow back their wells without any issue. Video below illustrate what it looks like after been deployed.
