Figure 27.
A series of maps summarizing properties relating to the reservoir quality of the Permian, Rotliegend Group, Leman Sandstone Formation. (A) Sandstone net-to-gross ratio expressed as a fraction; (B) sandstone reservoir thickness in meters; (C) sandstone reservoir porosity; (D) sandstone reservoir permeability. Depth structure refers to the depth to the top of the Rotliegend Group and was created using our well-tops database and the surface presented in Gast et al. (2010). Gross thickness is the true vertical thickness of the Rotliegend Group. Net-to-gross is the fraction of sand (shale volume <25%) within the Rotliegend Group interval. Average porosity is measured as the average effective porosity within only the sandstone beds. Average permeability was calculated using the geometric mean of values quoted in core laboratory reports.
