CDL completed a detailed geological and hydrological assessment of the Paleozoic saline aquifers east of Calgary. The objective of this study was to characterize the subsurface geology focusing on saline aquifers and aquitards. The hydrodynamics systems were analyzed regionally, and locally where sufficient data were present, to classify hydrodynamic systems using pressure, total dissolved solids and salinity to understand aquifer isolation and water chemistry. These separate systems assist in mapping future containment of the sequestered CO₂.
Several zones were examined, four zones were ultimately identified as having sufficient rock characteristics to meet the project criteria, and two areas of interest were high graded. The four zones identified from deepest to shallowest are the Basal Cambrian Sand (BCS), Beaverhill Lake (BHL A and B), Lower Leduc (Cairn) and Nisku formations.
With over $30 million invested, CDL's Technical Studies Library offers a one-of-a-kind resource for the E&P industry—covering petroleum systems, basin analysis, hydrogeology, and migration modeling across the WCSB, Williston Basin, and beyond.
