In addition to high helium flowing to surface, the Company encountered elevated hydrogen levels that flowed to surface. This concentration of hydrogen was measured at 2.2% using micro-GC equipment and is over thirty-seven thousand times above background levels (0.6ppm).
During the DST, it was noted that the downhole temperature gauges detected elevated temperatures (>80Β°C) associated with the release of hot Basement fluids, and subsequently, helium. These temperatures are indicative of a low enthalpy geothermal well. This geothermal energy has the potential to result in either a direct use project or a binary fluid electricity producing plant. Which in turn could be utilised in a number of ways which may include powering several functions in the development and production phase.
The Company owned Predator 220 drilling rig completed the drilling of the Itumbula West-1 well in eighteen days to a total depth of 961m measured depth and has successfully run wireline operations and completed three DSTs. NPT for the Epiroc Predator 220 drilling rig was reduced by over 350% between the Tai-3 and Itumbula West-1 wells, with zero downtime related to hydraulic issues. This improvement reflects and justifies the comprehensive upgrade and maintenance programme carried out post Tai-3.
In addition, the Company has successfully to date, completed the two well drilling campaign safely without any LTI.
