Reverse Phase Transition Multi-Dimensional Self-Supporting Fracturing Technology
Reverse Phase Transition Multi-Dimensional Self-Supporting Fracturing is a next-generation hydraulic fracturing technology that solves a fundamental limitation of conventional methods — solid proppant cannot reliably reach the far ends of micro-fractures and branch fractures, leaving large portions of stimulated reservoir volume effectively unsupported. Industry observations have repeatedly shown that proppant transport distance is often a small fraction of the actual hydraulic fracture length.
Our technology replaces the proppant-carrying paradigm with a phase-change fracturing fluid based on supramolecular chemistry. The fluid is injected as a liquid that flows freely into both the main fracture and the surrounding fracture network, then undergoes a controlled phase transition under formation temperature, solidifying in place to form a high-conductivity, self-supporting solid phase. The principle is simple — wherever the liquid reaches, support reaches.
How the Technology Works
The system uses a phase-change fracturing fluid that disperses throughout the fracture network as a liquid and then solidifies in place under formation temperature, creating deep, self-supporting conductive pathways for hydrocarbon production.
Key Features
Injection and dispersion
Self-supporting fluid and conventional water-based (channel) fracturing fluid are injected together. The self-supporting fluid disperses into droplets across the fracture network.
Phase change support
Heated by the formation, the self-supporting fluid undergoes an intelligent phase transition in the fractures, forming a solid phase that propagates support deep into micro-fractures and branch fractures — areas that solid proppant alone cannot effectively reach.
Flowback and production
The water-based channel fluid flows back to surface, and the space it once occupied becomes a high-conductivity flow path for oil and gas production.
Engineered Flexibility
The system is engineered for adaptability across a wide range of reservoir conditions and stimulation strategies.

Why It Matters
The technology fundamentally addresses several long-standing limitations of conventional fracturing — short proppant migration distance, limited fracture conductivity at the distal end, insufficient fracture-controlled reservoir volume, and sand plugging risk. By substituting in-place solidification for sand-carrying transport, it improves the utilization of microfractures and fracture-network reserves, particularly in unconventional plays. It can be combined with conventional, directional, volume, waterless, and acid fracturing techniques as part of a broader stimulation program.
