HYMA-Frac Tool for Multi-Stage Stimulation
Overview
High-efficiency, resettable straddle packer system for selective zonal stimulation
The HYMA-Frac™ is ANVEY’s next-generation straddle packer system, specifically designed for multi-stage stimulation in a single run. Engineered with a compact and deviation-friendly architecture, the HYMA-Frac™ provides precise zonal isolation, rapid resetting capabilities, and reliable retrievability, making it an essential tool for hydro-fracturing, acidizing, water-flooding, and chemical injection operations. It can be deployed with connected tubes or coiled tubing as well.
This innovative system features a dual-element sealing mechanism and a robust mechanical and hydraulic equalization path, ensuring balanced pressures across the tool. This design enables smooth deployment, secure setting, and effortless retrieval. Notably, the lack of shear screws in the hydraulic section enhances reliability and allows the tool to be fully resettable, even after multiple stimulation cycles.
The HYMA-Frac™ is designed for application in deviated, vertical, horizontal, shallow, and deep wells, providing the operational flexibility of a modular stimulation system while maintaining the durability required for harsh downhole environments. Whether the goal is selective zone treatment or multi-interval stimulation, the HYMA-Frac™ offers a cost-effective, field-proven solution among well intervention tools for modern well intervention programs.
Why choose hymafrac
Precision isolation. Multi‑zone flexibility. Reliable retrievability.
1. Multi‑stage stimulation in a single run
HYMA‑Frac™ enables repeated set‑reset cycles, allowing operators to treat multiple zones without pulling out of hole—significantly reducing operational time and cost.
2. Compact, slim, and deviation‑friendly
The short, streamlined design ensures smooth passage through doglegs and deviated sections, maintaining tool integrity and operational confidence.
3. Balanced pressure equalization
A dedicated mechanical and hydraulic equalization system stabilizes pressures across both sealing elements, simplifying running, setting, and retrieval.
4. No shear screws in the hydraulic section
The hydraulic mechanism is fully resettable, eliminating shear‑related failure modes and improving long‑term reliability.
5. Mechanical disconnect for contingency
In the event of an unexpected stuck‑string scenario, the mechanical disconnect protects the work string. The packer can be milled to re‑establish wellbore access.
6. No frac cups — more durability, easier running
By eliminating frac cups, HYMA‑Frac™ offers a more robust design with improved trip‑in performance and reduced risk of cup damage.
7. Compression‑set hanging assembly
The mechanical hanging assembly sets through compression—no rotation required—making it ideal for deviated and horizontal wells.
