Mbelele-1 Reaches TD
Noble Helium Limited (ASX:NHE) (“Noble Helium” or “the Company”) provides an update on drilling on at Mbelele-1 at the Company’s North Rukwa Helium Project in Tanzania.
Following the Company’s previous announcement of reaching tophole casing point after encountering gas and helium, the 8.5” open-hole section of Mbelele-1 has now been drilled to Total Depth (TD) of 400m TVD on 31st October local time.
A comprehensive suite of wireline logs has been run by SLB to collect subsurface information for petrophysical analysis. Initial interpretation in the 8.5” section, indicates stacked, interbedded sandstone-clay formations with the multiple helium shows above background, detected in the mudgas, coincident with permeable sandstone reservoirs below clay seals. The well was drilled intentionally ‘over-balance’ for safety reasons. Therefore, the wireline data are now being further studied to identify potential points for further gas and fluid sampling, where feasible and appropriate,
using modular formation dynamic tester (MDT) and/or mini-DSTs. MDT sampling and mini-DST runs are expected to take a number of days, after which Mbelele-1 will be plugged and abandoned as planned, with Mbelele-1 not designed to be a future production well.
The Marriott rig will then be rigged down and along with the SLB equipment moved 4km to commence drilling at the Mbelele-2 site.
The Company’s CEO and Co-Founder Justyn Wood commented:
“The continued helium shows at multiple levels in Mbelele-1 are very encouraging and in line with our interpretation of the exploration and seismic data that this is an active helium producing system and continues to support the Company’s well-researched thesis that the North Rukwa rift basin has the potential to emerge as a new globally significant primary helium province.
We look forward to understanding the nature of the helium shows and the reservoir potential in these deeper targets at Mbelele-1 and of course Mbelele-2, which also demonstrates anomalies on seismic consistent with gas presence.”
I think the term HE1 used after Tai-1 was 'no free gas'. This sounds to be the same.
