Origin and distribution of calcite concretions in Cretaceous Wall Creek Member, Wyoming: Reservoir-quality implication for shallow-marine deltaic strata

Calcite concretions reduce reservoir quality, but there are limited studies that examine 3D distribution and consequences for reservoir quality in outcrop analogs. We integrate petrography, diagenesis, and geochemistry with 3D ground penetrating radar and borehole data to investigate the timing, 3D distribution and origin of concretion growth within a mixed fluvial, tide influenced shallow-marine deltaic reservoir analog in Cretaceous outcrops in Wyoming.
