VStarter toe sleeve opens by applied pressure - the hydrostatic pressure and surface pressure combined, inside casing. After it opens, first stage of frac will be initiated and it establishes a flow channel for pumping balls or plugs for the subsequent stimulation. VStarter is designed to also activate on hydrostatic casing pressure alone. This compact, modular design allows for ease in handing and adds cost savings by replacing some conventional methods of perforating the toe section for fracturing operations.


  • Large exit flow ports for minimal flow restriction;
  • Improved efficiency by operating two or more tools allowing primary stage fracturing of the well;
  • One-piece Mandrel design provides a very robust tool design that withstands burst pressures in excess of 10,000 psi;
  • Pressure rating can be customized;
  • 4.5” & 5.5” design models are available, other sizes can be customized for customer requirements;
