ACE FT 7 | Sedimentologic and Sequence-Stratigraphic Response of Paralic Deposits to Changes in Accommodation: Predicting Reservoir Architecture, the Book Cliffs of Eastern Utah
Society for Sedimentary Geology (SEPM)
Thursday, 11 June – Sunday, 14 June 2020, 8:00 a.m.–8:00 p.m. | Utah
Who Should Attend
Geologists, Engineers, Petrophysicists, Geophysicists who are interested in understand stratal architecture at scales ranging from reservoir to regional scale.
This trip allows participants to understand sequence stratigraphic methods as applied in both outcrop and subsurface focusing on alluvial to marine siliciclastic depositional systems.
The Book Cliffs of eastern Utah are among the most spectacular outcrops of marginal marine strata anywhere in the world. Gentle structural dips and desert-like environments allow for the correlation of stratal units across miles of superb exposure. The Book Cliffs have served as a field analog and laboratory for siliciclastic alluvial and marginal marine systems as well as sequence stratigraphic concepts. These superb exposures of the Upper Cretaceous Blackhawk Formation and associated units are used to demonstrate regional-scale, field-scale, and reservoir-scale stratigraphic relationships and their application to subsurface studies. Detailed facies analysis is used to introduce concepts of parasequence stacking patterns that can be used to predict reservoir occurrence. These predictions can be tested by observing larger-scale outcrop exposures. During the field trip we will make use of subsurface correlation exercises and core photographs to link outcrop observations to practical subsurface application.
