Area of tight shale and deep coal gas prospectivity

\n## **Abstract** \nThis polygon outlines the cumulative prospective area of interest for three gas play types (shale, tight and deep coal gas) in the Cooper GBA region. As detailed in Lech et al. (2019), the area of interest for each play type was derived from the relative prospectivity maps using a cut-off value of 0.2. This value was chosen as it best represented the envelop around key wells targeting each play type. Significant overlap is present between the three play types.\n\n\n## **Attribution** \nGeological and Bioregional Assessment Program\n\n\n## **History** \nThis polygon outlines the cumulative prospective area of interest for three gas play types (shale, tight and deep coal gas) in the Cooper GBA region. \r\nAs detailed in Lech et al.
