ZoneSelect SingleShot Stimulation Sleeve

Contact

Stimulates up to 67 zones in a single run

Applications

  • Horizontal and vertical wells
  • Multizone wells
  • Cemented and openhole completions

Features and Benefits

  • The SingleShot sleeve can stimulate multiple zones in a single run without thru-tubing intervention, which enhances operational efficiency and reduces the time required for stimulation.
  • The sleeve insert has a mechanism to prevent the sleeve from rotating while it is open or closed, which enables efficient mill out.
  • The sleeve maximizes flow area through the ports, which reduces erosion and provides more volume for stimulation.
  • The sleeve is compatible with all ZoneSelect ball and seat systems, which helps to increase stage count and provides an optimal solution for each application.

Tool Description

An integral part of the Weatherford ZoneSelect® completion system, the SingleShot stimulation sleeve enables operators to stimulate up to 67 zones in a single run. The maximum stage count can be increased when the SingleShot sleeve is combined with other ZoneSelect sleeves.

The SingleShot sleeve shifts open when a ball, which drops from the surface, lands onto an integral seat within the sleeve and applies tubing pressure. When shifted, the sleeve locks in the open position. The stimulation treatment can then be pumped into the zone. Weatherford uses engineered shear rings for accurate shifting pressure and surface indication. The continuous method of isolating below the sleeve, shifting to open ports, stimulating, and then moving to the next zone enables stimulation to be completed quickly and efficiently.

The SingleShot sleeve is designed for interchangeable ball seats. All ball seats are made from flame-hardened cast iron for efficient milling. Various Weatherford stimulation balls enhance milling efficiency or dissolve completely downhole, which eliminates milling and reduces rig time.
