Organic geochemical analyses were performed on Paleozoic shales and oils from the northern Denver basin to determine oil-source bed relationships. Two general oil types were recognized: oil produced from reservoirs of Virgilian and Wolfcampian age in northeastern Colorado and Nebraska, and oil produced form the Lower Permian Lyons Sandstone near the basin axis in Colorado. Low-gravity oil (20/sup 0/ API) produced from the Virgilian-age reservoir at the Amazon field (Nebraska) and a higher gravity oil (37/sup 0/ API) produced from a well near the Amazon field (Wespro 1-23 Lyngholm) can be distinguished geochemically from the other Virgilian-Wolfcampian oils studied and may be genetically unrelated to them. For comparison, oils were analyzed from the Minnelusa Formation (Permian-Pennsylvanian) in the Powder River basin. These oils are geochemically unlike any Paleozoic oils analyzed in this study in southeastern Wyoming and Colorado.
