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 an evolution of the current state of the art, featuring a range of improved technologies, the most important of which are:
Re-usable automatically set sealing elements integrated into the tool.
Uniquely formulated propellant developed exclusively to deliver a long-duration, pulsed pressure profile
One of the key aspects of the PSI-CLONE™ tool is its ability to deliver long duration pressure profiles, thanks to our unique new sealing elements. Early testing showed that conventional wellbore packers would not be able to withstand the pressures our tool would generate, so we are developing our own propietary new sealing solution.
PSI-CLONE's integrated sealing elements are:
Automatically deployed along with ignition of the solid propellant
Fully capable of sealing against the pressure generated by the solid propellant
Designed to fully relax once pressure is removed (solid propellant burns out)
PSI-CLONE™ will be the first tool to use specially designed propellant formulations to achieve the optimum pressure-time history for every formation and well. The PSI-CLONE™ tool is designed to be fully plug-and-play with different propellant formulations, so that one tool, along with the right propellant formulation, can be used for stimulations in many applications.
Additionally, our propellants are safe to handle and transport, and will be independently lab tested to ensure that there are no harmful by-products, either to personnel or the environment.
The PSI-CLONE tool offers many economic, environmental and operation benefits over traditional hydraulic fracturing operations:
|Equipment Required||One coiled tubing unit||Multiple pumper trucks and water tanks|
|Water Requirement||In situ only||Average of 5 million gallons|
|Proppant Requirement||None||Up to 4 million pounds|
|Casing Requirement||None||Special casing for separating zones/re-entries
(i.e. ball drop, sliding sleeve)
|Staging||No restriction on number of stages or lateral lengths||Maximum number of zones depending on well completion|
|Time Duration (Single Zone)||~30 seconds||Multiple hours up to days|
|Multiple Zones||Can string tools to simulatneously treat multiple zones||Most zones must be treated seperately|
|Environmental||No contaminated water to potentially damage local environment||Water must be recycled or disposed, risk of spill and groundwater contamination|
|Infrastructure||Small equipment required protects local infrastructure||Equipment, water and proppant delivery traffic damages roads, inconveniences residents|
