Sliding sleeve multi-packer systems
Since 2020 Solexperts cnstructs packer systems with sliding sleeves. The central tube of sliding sleeve packer systems is equipped with sliding sleeves. Slidign sleeves give access to the packed intervals and are opened and closed with a so-called shifting tool (see figure below left).
Advantages of sliding sleeve packer systems
- Large injection flows at high pressures (important for stimulation)
- Many intervals can be equipped with sliding sleeves in one borehole
- Robust oil and gas technology
