Theses and Dissertations
The Birdbear Formation of northwestern North Dakota is a carbonate-evaporite unit deposited on a rimmed carbonate platform during the Late Devonian. The upper and lower contacts are conformable and the formation has been previously divided into two informal upper and lower members. Analyses of core intervals, thin sections, total organic carbon, and wire line logs have allowed for the identification of three informal units that are divided based on lithologic changes, depositional settings, and reservoir characteristics of the formation. Each unit is identified and mapped across the study area using core to log correlations. The units are recognized and named …
