Chemostratigraphic and depositional characterization of the Niobrara Formation: Techniques for assessing lateral heterogeneity, CEMEX Quarry, Lyons, Colorado, Denver-Julesburg Basin
Abstract:The Late Cretaceous (89–82 Ma) Niobrara Formation is the primary target for unconventional horizontal well activity in the Denver Basin. With an abundance of horizontal activity, the question of well-length scale lateral heterogeneity becomes paramount addressing steering practices, completion, and ultimately well performance. We have incorporated detailed core description, high-resolution chemostratigraphy, and petrophysical logs from four near-surface cores taken at the CEMEX Lyons Quarry to assess lateral h… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
