The SOH  is a high performance packer with a single pack-off assembly, which is designed for open hole  application. The SOH is a part of the “SMF” multi-stage stimulation system and provides secure, reliable, high pressure annular isolation.The unique modular design allows one or more packers to be stacked within a given zone at the operator’s discretion to achieve multi-redundant independent annular isolation sealing. The extremely compact design provides easy to handing and rig floor, liner string flexibility and trouble free deployment into even the most difficult well profiles. The SOH is set by applying pressure to the tubing string and high performance is fully retained the packing element reliably and holds the extreme differential pressures from above and below through multi pressure and direction cycles.

Alternatematerials and configurations are available for severe environments and higher differential pressure ratings. A full line of accessory equipment is available which can  provide a complete open hole multi-stage stimulation system.
