RocketFrac PSI-CLONE™ Tool

Render of the PSI-CLONE tool

RocketFrac's patent pending tool provides fracture zone isolation for unprecedented performance in solid rocket propellant applications.

Existing propellant fracturing technologies have been successfully deployed in hundreds of wells with exceptional results. However, despite their success, existing tools face limitations which constrain their use to short duration treatments in vertical wells. These limitations have prevented their use in widespread applications.

PSI-CLONE™ is a completely new application of propellant fracturing, featuring a range of cutting-edge technologies, the most important of which are:

  • Re-usable, fully integrated well bore isolation mechanisms

  • Uniquely formulated, proprietary solid rocket propellant developed to deliver a long-duration pressure profile

Revolutionary Isolation Solution

One of the key aspects of the PSI-CLONE™ tool is its ability to deliver long duration pressure profiles, thanks to our unique new isolation mechanisms. Conventional well bore packers are unable to contain the exhaust gases of a solid rocket propellant.

PSI-CLONE's integrated isolation mechanisms are:

  • Automatically deployed

  • Fully capable of containing the pressure generated by the solid propellant

  • Designed for easy removal from wells

  • Re-usable

Oilfield Specific Design

PSI-CLONE™ is the first tool to use a specially designed propellant formulation to achieve the optimum pressure profile for effective well stimulation. The propellant and initiation mechanisms are built specifically for use on wellsites, and are fully compliant with all oilfield safety requirements. Our propellant is safe to handle and transport and has no harmful by-products, eliminating those risks to both personnel and the environment.
