Tai-1 has successfully identified helium shows within all three target formations which confirms the presence of a working helium system in the Rukwa Basin. \n \n \n \"Frustratingly, due to poor and deteriorating hole conditions, including large washouts across much of the Karoo, we were not able to run wireline tools downhole beyond 882m and have subsequently not been able to log the main Karoo Formation. \n \n \n \"Thinly-bedded sands in the uppermost Karoo that we were able to log have no indications of free gas. Petrophysical analysis indicates that these helium shows are associated with gas-cut-brine or 'fizz-gas', which is formation water saturated with helium. These were the only helium shows tha...
