Helium Gas Show Confirmed and Delay to Tai-112 Jul 2021 08:31
Helium Gas Show Confirmed
Delay to Tai-1
Helium One (AIM: HE1), currently drilling at its 100% owned Rukwa Project In Tanzania, is pleased to announce a further helium gas show in drilling mud (a "Gas Show") in the Red Sandstone Group and sidetrack from Tai-1 well following loss of the drill string at 561 meters.
Highlights:
· Helium gas shows identified in stratigraphy above our primary targets from 552 metres to 561 metres as measured by the on-line gas chromatograph
· Gas show supported by indications of gas visually identified as bubbles in drilling mud returns at surface
· Helium shows continued to 561 metres, at which point drilling operations were suspended due to parting of drill pipe in the midst of drilling the gas show
· Mitchell Drilling has been unable to recover the lost drill pipe from the hole to date with subsequent delay to drilling operation resulting in the management decision to sidetrack drilling from above the lost pipe at 483 meters
David Minchin, Chief Executive Officer, commented:
"The identification of helium gas shows in the Red Sandstone Group between 552 and 561 metres is another unexpected, but positive result as this zone was previously considered to be of low prospectivity.
"This gas show, along with our earlier reported gas show announced on 22nd June, demonstrates a working helium system and supports helium prospectivity for additional gas shows throughout the stratigraphy.
"Visual identification of bubbles in mud returns also offers circumstantial evidence of free helium gas in the sub-surface. However, it is important to note that this interval needs to be logged with wireline before a pay zone can be determined.
"The delay caused by the loss of drill string in the midst of the drilling is unfortunate, however contingency plans have been implemented to sidetrack from above the lost pipe and continue drilling to test both the Red Sandstone gas show and priority target horizons beneath. This option allows us to utilise the existing 483 meters of already completed drilling rather relocating to a new location.
"With the above indicators already identified we look forward to a successful completion of drilling on this target location."
