  1. Low Risk Cost Effective Efficient Fracture Evaluation Powered by Quad Neutron Technologies Ltd.

  2. Fracturing Evaluation Challenges • Radioactive Fracture Tracing Materials – High HSE risk – Contamination control costs – Radioactive tag eventually expires – Cannot discriminate fracture direction Powered by Quad Neutron Technologies Ltd.

  3. Why Trace Your Frac? • Identify offset well interference • Identify frac stage interference • Identify zonal coverage Powered by Quad Neutron Technologies Ltd.

  4. Existing Frac Tracing Methods • Radioactive (RA) isotopes • Harmful to our health and our environment • Common Oilfield RA isotopes half life's – Iridium 192, 74 days – Scandium 46, 84 days – Antimony 124, 60 days • RA Isotopes are not safe for 7 half life's – Iridium-192, 518 days Powered by Quad Neutron Technologies Ltd.

  5. Quad Neutron & Boron Carbide Fracturing Evaluation Solution • Radioactive Fracture Tracing Materials – High HSE risk – No exposure risk to personnel – Contamination control costs – No Radioactive sand disposal and monitoring – Radioactive tag eventually expires – No time limit / Boron Carbide never expires – Cannot discriminate fracture direction – Quad Neutron dual physics can be used to discriminate fracture direction Powered by Quad Neutron Technologies Ltd.

  6. Boron Carbide & Quad Neutron • Higher quality data to existing methods • No exposure risk to personnel • Matched to any proppent size • All frac types including N 2 • No time limit / Tag doesn’t expire • Near vs. Far tag placement using the Quad Neutron Powered by Quad Neutron Technologies Ltd.

  7. Why Boron Carbide (CB4)? • Characteristics: – Similar density as frac sand – Chemically inert – Large absorber of neutrons • Pros: – Higher quality data to existing methods – No exposure risk to personnel – Matched to any proppant size – All frac types including N 2 – No time limit / Tag doesn’t expire – Near vs. Far tag placement with Quad Neutron • Cons: – Before pass required for neutron comparison – Only two tags available Powered by Quad Neutron Technologies Ltd.
