1. Installation & Commissioning (Current Phase)
Duration: 7–10 days
The crew must "run" the ESP into the hole on the end of a production string. This is a slow process where the power cable is clamped to the pipe every few meters to prevent damage. Once at depth, the surface control systems (the "Variable Speed Drive") must be wired up and tested.
A short RNS confirming that "ESP installation is complete and commissioning has commenced." should arrive at this point...
2. The "Drawdown" Phase (The First Results)
Duration: 2–3 weeks
Once the pump is turned on, it begins lifting water to the surface. The goal is to lower the pressure at the bottom of the well (the "drawdown") to allow the helium bubbles (the "Free Gas") to expand and flow...
During the first 14 days, you often see "slugs" of gas. The market is looking for stable, sustained flow.
An update RNS usually follows roughly 14 days after the pump starts, detailing initial flow rates and helium concentrations should be released at this stage...
3. Stabilised Flow & Gas-Water Ratio (GWR)
Duration: 4–6 weeks total
The company needs to prove that as they pump water, the gas rate stays high (or increases). This is the data required by independent experts (like Sproule-ERCE) to officially upgrade "Resources" into "Proved Reserves."
The most immediate news to look for is the confirmation of first sales in Colorado. While the ESP is the "scale" play, the first US cheque is the "survival" play. Following that, the focus shifts entirely to the Itumbula West-1 (ITW-1) flow rate....
