In case it helps Ben...
From the RNS 4 September 2024 EWT flow results...
"Internal modelling demonstrates that this could increase to 20,000 bpd of fluid with artificial lift in the development phase. On this basis, the Company estimates the actual flow rate would increase to 6,176 scf/d of helium, when applying an average concentration of 5.5% helium".
They didn't mention gas water ratio in those results but you can infer it by simply reversing the calculation and comparing it with the probability scenarios in the CPR, which had access to the modelling. Their assumption was a gas water ratio of 0.99 (i.e. 99% gas and 1% water), which is also used in the P10 case in the CPR. For comparison, the latest ESP test results averaged 0.05 (5% gas and 95% water).
ESP results -
The flow test isn't a production test, so you can't just extrapolate from the results. If you did then the assumed helium output would only be about 227-364 scf/day, which is less than 5% of the maximum aspired to in the 2024 RNS, but it's still better than the P90 case in the CPR.
They now have three variables to work on for production modelling - liquid production rate (pumping), gas water ratio (liberating free gas up the pipe without diluting it), and helium concentration (targeting the drill into the strongest helium zones).
If they can both increase the flow to 20,000 bbl/d, and increase the gas ratio to 0.25, while maintaining a concentration of 5.4%, then the model might predict around 1.5 Mscf/d helium. If they could also tap anything like their maximum reading of 9.2% (P10 = 8.8%) then they might top 2.5 Mscf/d. But the gas water ratio remains the key variable where the original modelling was pushing the limits of probability (CPR P10).
But all those readings are based on Itumbula. If they can now use this knowledge to drill new wells elsewhere with stronger results then the odds may increase.
