Helium One has reached total depth at its Itumbula West-1 well in Tanzania, with its CEO, Lorna Blaisse, confirming elevated helium shows.
In an update released today (25th January), the helium exploration company said the helium shows were over twenty times above background while drilling through the Lake Beds Formation, Red Sandstone Group, Karoo, and Basement targets.
In addition to helium, the well also encountered a high concentration of hydrogen in the Lakebed Formation over a six-meter interval. Hydrogen shows also continued through the Karoo section and into the Basement.
Blaisse expanded, “The initial results from the Itumbula West-1 well are very positive. The wireline logs are the crucial next step in identifying which intervals we will test and sample for further evaluation.”
“By running an image log this time around in conjunction with a full logging suite and having the well test equipment on site, we are able to fully evaluate the helium and hydrogen potential in this well and establish whether we have a viable helium and/or hydrogen play.”
Helium One will now rig up for wireline operations to log the entire well. Following wireline operations, the team will then perform an open-hole well test across the faulted zone and additional zones of interest once a full petrophysical analysis of the wireline logs is complete.
Downhole samples will be taken and evaluated onsite using the pressure-volume-temperature field laboratory. Any additional samples will be sent off to a specialised noble gas laboratory for further verification.
Helium One started drilling at the Itumbula West-1 well earlier this month (January 2024).
