Final Gas Content Testing Reids Dome
The Company has received the final Gas Content Testing report on the core samples obtained from the Nyanda-4 well, drilled by the Company in late 2018.
The final average of the measured gas content from the coal desorption testing is 13.75 m3/t from 10 samples. Gas content for the thickest cored seam is 16.94 m3/t. The highest value obtained was 17.16 m3/t and the lowest value was 8.30 m3/t. These data confirm the range expected by the Company.
These figures replace all prior advices from the Company as to content from the Nyanda-4 well, including in presentations dated 8 October 2019 and 22 October 2019.
Nyanda-4 was the first well drilled in the permit to test the gas potential of the Reid's Dome Beds coal measures and has established a new coal seam gas play in the Denison Trough. The well was drilled to a total depth of 1200m, from which 150m of core was obtained, commencing at 394m depth. Wireline logging at total depth confirmed 40.4m of net coal in multiple seams up to 4m thick, and a further 25m of carbonaceous shales and thinner coal seams (i.e. <0.2m), indicating 65m of coals and carbonaceous shales (excluding conventional sandstones).
As previously advised, drilling activities are currently underway approximately 12 kilometres north within PL 231 at Aldinga East-1A, with both coal seam gas and conventional gas encountered during that drilling to date. Further updates will be provided once drilling at Aldinga East-1A reaches total depth and testing is undertaken.
