Unlocking Reservoir Potential

---

Current hydraulic fracturing methods are inefficient, environmentally challenging and costly—especially for refracturing depleted shale wells. They require excessive fresh water (Scanlon, 2014; Scanlon et al., 2024), utilize large volumes of diesel energy, emit large volumes of greenhouse gases (Vafi, 2016), and enhnace seismic risk (Shultz et al., 2020). Additionally, the surface-generated pressure dissipates significantly before reaching the reservoir (Abdulwraith, 2024), limiting fracture complexity, proppant distribution, and resulting in recovery factors as low as 8% after first-cycle stimulation (Trefis, 2015).

HydraSTIM (U.S. Patent #12,084,954)  is an innovative downhole pulse-based stimulation system that delivers localized, high-energy pressure pulses at depth, reducing surface energy requirements while enhancing fracture efficiency. The innovative design integrates conventional hydraulic fracturing operations with downhole pulse technology to improve reservoir productivity, reducing environmental footprint and improving ROI.

The system comprises three integrated components.
(1) The HydraSTIM Pump, positioned in the vertical section of the wellbore, converts drill string mechanical energy into pressure pulses via a piston-driven mechanism.
(2) The HydraSURGE Tool, located at the reservoir, amplifies these pulses using the Water Hammer Effect to generate Rectangular Pulse Hydraulic Fracturing (RPHF) pressure waves; and
(3) The PulseFRACK software captures and analyzes downhole pressure responses in real time to interpret fracture behavior and optimize pulse generation.

This closed-loop configuration improves fracture initiation, promotes fatigue-driven fracture growth, enhances proppant placement, and increases overall fracture density. The result is higher oil and gas recovery, reduced environmental impact, and lower operating costs—directly addressing commercial and environmental challenges in redeveloping mature wells in unconventional plays.

Generates high-pressure pulses near the reservoir—not at surface—enhancing fracture initiation, propagation, and energy transfer.

Combines sine-wave and rectangular pulses to drive deeper fracture networks and improve proppant transport in tight formations.

Eliminates diesel-intensive surface fleets—reducing CO₂ emissions and water use by up to 80% and 20%, respectively.

Creates complex fractures through cyclic fatigue, unlocking bypassed zones and boosting ultimate recovery without redrilling.

Integrates downhole sensors and AI-ready edge computing to optimize pulse delivery dynamically, improving efficiency and safety.

Designed for standard rig compatibility, WellSTIM avoids HPHT material constraints—enabling cost-effective, field-ready deployment.

By positioning pressure sensors on the downhole HydraSTIM tool—closer to the reservoir—PulseFRACK captures stronger, higher-resolution pressure reflections. This enables more accurate interpretation of fracture geometry and propagation behavior, turning pressure transients into actionable diagnostic insight.
