ULW Inorganic Proppant for EGS and Deep Geothermal Applications
NovelProp develops a proprietary ultra-lightweight (ULW) inorganic proppant platform for enhanced geothermal systems and deep geothermal applications. The technology is being designed for water- and brine-based transport, elevated temperature environments, and staged technical validation for future field and pilot use.
The development focus is on engineered inorganic particles intended for geothermal stimulation environments where transport behaviour, thermal stability, and application-specific material performance are important. The platform is being advanced for enhanced geothermal systems (EGS) - relevant conditions and adjacent subsurface energy applications.
Advanced ultra-lightweight inorganic proppant technology for enhanced geothermal systems, deep geothermal wells, and next-generation subsurface energy applications.
Why geothermal needs a different proppant approach
EGS place demanding requirements on stimulation materials. Many conventional proppants were developed for oil and gas workflows rather than long-duration geothermal environments involving elevated temperature, saline fluids, and pressure to reduce chemical intensity. NovelProp is being developed with this operating context in mind.
Too heavy for lower-chemical transport
Many conventional proppants rely on more viscous carrier systems to support placement, increasing chemical load and operational complexity.
Performance pressure under geothermal conditions
Long-duration exposure to heat and brine can challenge material stability and long-term application relevance.
Limited placement visibility
Without a practical diagnostic pathway, it can be harder to evaluate placement behaviour and accelerate learning in pilot settings.
A proprietary ULW inorganic platform in development
NovelProp is developing a proprietary ultra-lightweight inorganic proppant platform based on its own materials know-how. The current focus is on combining low apparent density, geothermal-relevant durability, and compatibility with an optional non-radioactive diagnostic pathway within a structured validation framework.
Current public development profile
Apparent Specific Gravity (SG) : ~1.1-1.3 g/cc
Intended transport context:

Why this development direction matters for geothermal projects
Lower-chemical stimulation logic
The platform is being developed for use in water- and brine-based systems, with the goal of reducing dependence on heavier gel systems.
Geothermal-focused materials direction
Current work is centred on operating contexts where thermal and saline exposure are important.
Structured technical learning
An optional diagnostic pathway may support more informative pilot and field evaluation workflows.
Staged validation pathway
NovelProp is progressing through stepwise material and application-focused validation.
Current development status
Initial material lots produced
Baseline technical work underway
Application-relevant validation planning in progress
