Core Description and Petrographic Analysis of the Desert Creek Sequence (Middle Pennsylvanian) in the Aneth Field, Paradox Basin, SE Utah.
The petroleum system of the Aneth Field in southwestern Utah is centered upon a 70 meter-thick, horseshoe-shaped carbonate buildup that covers approximately 140 square miles. This presentation focuses on the sedimentology, microfacies, and systems tracts of the Desert Creek third-order sequence along a roughly southwest to northeast transect of the southern part of the Aneth buildup, in the Ratherford Unit. This study is based upon analysis of four cores and corresponding logs from the buildup, anchored by off-mound logs on the north and south edges of the complex. Analysis is based upon integrated study of logs, core, and thin sections. At this early stage of study, focus is upon lithofacies and grain associations with analysis of reservoir properties and diagenesis to follow.
