Codell Sandstone oil production trends, Northern Denver Basin, Laramie County, Wyoming Mar 14, 2024 Toner, R.N.; Campbell, E.A.; Lageson, D.R., 2024, "Codell Sandstone oil production trends, Northern Denver Basin, Laramie County, Wyoming", https://doi.org/10.15786/13688560, Wyoming Data Repository, V1 The oil-bearing Codell Sandstone was historically deemed uneconomical due to its low porosity and permeability, and its lack of traditional hydrocarbon trap. With recent advances in horizontal drilling and hydraulic fracturing (frac) methods, this unconventional tight sand is now proving to be a highly productive oil reservoir. This study investiga...
