Well, I see your point regarding compartmentalization . The truth here is that the wells are cheap to drill and the ROI on each well is a justification for further drills given the price of helium.
Fair enough if you decide to sell. Sad that the 3d seismics would take a while to approve as it is probably important in the scheme of things, but the fact that they have been drilling blind and have been able to come up with 5 over pressured wells must count for something!
From Perplexity:
Yes, Topaz's exceptionally high helium grades (8–14.5%) can potentially deliver comparable or superior ROI to conventional porous helium fields, despite zero matrix porosity, by offsetting higher drilling density with richer gas streams and lower processing costs.
Grade vs. Porosity in ROI Drivers
High-grade helium like Topaz's slashes separation costs, which dominate helium economics (often 60–80% of OPEX). Conventional fields like Cliffside (1.8–2% He) require massive gas throughput for the same helium output, while Topaz needs far less volume—reducing plant size, energy use, and CO2 emissions.
Key Economic Offsets at Topaz
Rich gas stream: 85% marketable (He + CO2 + He-3), vs. nitrogen-diluted fields needing cryogenic separation; CO2 byproduct adds revenue via carbon credits.
Natural flow, no frac: Cuts well costs vs. stimulated plays; high bottom-hole pressures (145–151 PSIG) support long-lived production.
Proximity advantages: Minnesota infrastructure (power, roads) trims capex by 20–30% vs. remote fields.
ROI Comparison Scenarios
Factor Porous Fields (e.g., Cliffside) Topaz (Fractured, High-Grade)
Factor Porous Fields (e.g., Cliffside) Topaz (Fractured, High-Grade)
He Concentration 0.5–2%
8–14.5%
Wells per MMcf He 1–2 (large drainage) 3–5 (if compartmentalized)
Processing OPEX High (dilute N2) Low (concentrated, dry)
Net ROI Potential 15–25% IRR (mature) 25–40%+ if connectivity holds
Compartmentalization risk means more wells (higher upfront capex), but Sproule pegs commerciality odds at 65% based on grades alone; mid-2026 economics will quantify via interference tests. He prices ($12+/m³) and US supply gaps amplify upside.
