I'm a first year Master's student studying the Campanian age, shallow marine, clastic sedimentary deposits of the Cretaceous Western Interior Seaway in Wyoming. My research focuses on the Blair Formation, which is considered to be an isolated shallow marine sandstone. Isolated shallow marine sandbodies are abundant along the Cretaceous Western Interior Seaway and commonly act as hydrocarbon traps. An integral part of modeling these reservoirs is the determination of their depositional process which informs about the structures and architectures within the formation (that can act as baffles and barriers to flow). However, the depositional processes of these sandbodies are recurrently debated. I plan to integrate outcrop data with subsurface data (such as wireline well logs and core), to analyze the facies/ architecture of the fine-grained Blair Formation, and to ultimately develop a paleoenvironmental and unconventional tight gas reservoir model of the Blair that can act as an analog for other less well-exposed isolated shallow marine sandstones.
