A Layman's RNS analysis18 Feb 2026 08:18
Here is my analysis as a layman for the latest RNS against the CPR. Using the data for the GWR and helium concentrations I will use the formula to calculate the relative effectiveness against the P90 and P50 cases.
( RNS he% x RNS GWR) ÷ ( CPR he% x CPR GWR)
P90. (0.054×0.05)÷(0.033×0.04) = 2.04
P50. (0.054×0.05)÷(0.052×0.25) = 0.20
So in this we are twice as good as the P90 case but only 20% of the P50 case.
As the pump and seal were not placed in ideal positions the basement and aquifer mixed. (To what extent we do not know). Assuming the peak can be achieved consistently with correct placement then we have:
P90. (0.092×0.1)÷(0.033×0.04) = 6.97
P50. (0.092×0.1)÷(0.052×0.25) = 0.71
So in this we are seven times as good as the P90 case but only 70% of the P50 case.
Regarding the contingent resources we need to consider the rate of extraction. From the CPR we have
"Helium One models a low case at a lower initial liquid rate, 12,300
bbl/d, which decreases with time (Figure 3.13), with which Sproule ERCE agrees."
The last RNS stated that the consistent rate was 15,000 bbl/d. So it is possible that the figures above could be increased by about 22% (15000÷12300). ( It is likely tham I am wrong about this assumption) This would give the range of P90 (2.49 to 8.5) and P50 (0.24 to 0.87)
