Origin and distribution of calcite concretions in Cretaceous Wall Creek Member, Wyoming: Reservoir-quality implication for shallow-marine deltaic strata
SL Nyman, MR Gani, JP Bhattacharya, K Lee - Cretaceous Research, 2014 - Elsevier
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. Calcite concretions, varying in size and shape from 70 cm to 5.5 m in length and …
