Previous company that drilled in the Leduc Formation People have been asking questions about previous drillings... The first link seems pretty informative about the entire Leduc formation - and provides some information into the Leduc reef trend that First Helium is drilling.
The second link has a map that shows where First Helium site is and I included it for reference purposes to the link
"There is a long history of hydrocarbon discovery and production from the Leduc Formation, starting with wells drilled in 1947 close to the city of Edmonton by Imperial Oil (Leduc No. 2 and Leduc No. 3). Prior to the discovery of Leduc No. 1 (Nisku Formation), 133 dry wells were drilled into the Devonian succession by Imperial Oil (Jaremko, 2013), proving the complexity of the spatial distribution and petroleum systems in the Devonian carbonate buildups. Leduc reservoirs have been prolific, with the second largest Devonian oil pool in Alberta within the Redwater Leduc reef northeast of Edmonton (Figure 1.2) (Chow et al., 1995). Many smaller but significant oil pools are found within the buildups of the Leduc Formation across the province."
