Who We Are

Founded by Milan Simic, a 25-year veteran in oil & gas operations, corporate finance, and innovation strategy, Simic Energy Services is grounded in deep industry knowledge and driven by the vision of a clean, radical-chemistry-based hydrogen future.

MISSION

To transform legacy oilfield infrastructure and chemistry into the foundation of a scalable, abundant hydrogen economy — one that is energy-dense, emissions-minimized, and geopolitically stable.

WHY WE'RE DIFFERENT

🔬 Scientific Leadership: We lead global development in Radical Thermochemical Chain Reactors (RTCRs), in-situ radiolysis, and subsurface serpentinization tools.

🛠️ Field-Tested Roots: Our technologies integrate seamlessly into oilfield operations — no greenfield guesswork, just energy production evolved.

♻️ Closed-Loop Carbon: We don’t just reduce CO₂ — we trap it underground while unlocking massive hydrogen reserves.

We operate under an active trade secret and provisional patent framework across the following domains:

 

  • Subsurface hydrogen generation

  • Radical propagation control

  • Serpentinization enhancement

  • Radiolysis systems

  • High-pressure catalytic fracturing
