Helium One flows up to 7.6% helium at ITW-1

Helium One Global Ltd said it had successfully flowed up to 7.6% helium to surface on completion of the first phase of the extended well test at Itumbula West-1 at Rukwa in Tanzania.

Operations on the faulted Karoo Group interval resulted in an average flow of 786 barrels per day (bpd) for a period of five days with helium gas in solution and “little to no air contamination” in a “pure helium/nitrogen mix”.

The subsurface team will evaluate the data and, following completion of the Basement extended well test, determine a maximum flow rate.

“This is a globally unique helium play and it has taken a lot of hard work and collective effort across multiple disciplines to establish how this system works in the southern Rukwa Basin,” added chief executive Lorna Blaisse.

“We have gained a huge amount of information from this Karoo EWT and look forward to seeing what the fractured Basement EWT is going to yield.

“Once we have completed testing on this second interval, we plan to finalise our integrated subsurface modelling and resource estimates to complete our feasibility study.”
