Muddy Formation Outcrop Field Trip
A field trip guide was prepared for the August 2013 Muddy Formation outcrop field trip near Hulett, Wyoming. Participants were from Denbury Resources Inc. and the EERC. Regional uplift in the area of the Black Hills during Tertiary time, and subsequent erosion, has exposed significant outcrops of the Muddy Formation in northeastern Wyoming. The proximity of these outcrops to their deeply buried (~4500-ft) equivalents in the Bell Creek oil field provides an excellent opportunity to understand the potential heterogeneities in the reservoir system. Although numerous wells and core are available in the field, many cores had poor recovery; thus only 25 cores are available to interpret vertical and horizontal variations in facies and internal structure. This limited set of data and their distribution are not sufficient to resolve the 3D geologic subtleties believed to exist in the reservoir. Outcrop examination provides a source of extensive geologic data in the X, Y, and Z directions. This assists in gaining an understanding of regional structure, facies, and heterogeneities that can be correlated back to core and the 3D geologic models.View/Download Document
