Abstract

fetched live from OpenAlex

ABSTRACT Deep saline aquifers and depleted reservoirs are prime candidates for CO 2 storage, but feasibility assessments remain limited in regions with little oil and gas activity, such as the Lower Mainland of British Columbia (LMBC), Canada. This study evaluates the CO 2 storage potential of the Georgia Basin strata beneath the LMBC, focusing on three intervals (Nanaimo Group, Huntingdon Formation, and Boundary Bay Formation) in Western, Central, and Eastern LMBC. Eastern LMBC holds limited potential for CO 2 storage due to both the shallow depth of strata in that region and the high geological uncertainty resulting from limited subsurface data. The Upper Cretaceous Nanaimo Group across the entire LMBC is unsuitable for CO 2 injection because it has very poor reservoir quality (generally &lt;1 mD permeability and &lt;8% porosity). In contrast, the Paleogene Huntingdon Formation in Western and Central LMBC contains thick successions of reservoir‐quality rock (average thickness: 110 m, porosity: 15%), though its low permeability (≥10 mD) may restrict injection rates. Its estimated CO 2 storage capacity is ∼400 Mt, making it a secondary target. The Neogene Boundary Bay Formation, also in Western and Central LMBC, offers the most favorable conditions, with higher permeability (13–67 mD), porosity (18%–21%), and thick reservoir intervals (up to 155 m). It has an estimated CO 2 storage capacity of ∼430 Mt. With low fault density and minimal wellbore leakage risks, the Boundary Bay Formation and then the Huntingdon Formation below Western and Central LMBC are recommended as the primary targets for CO 2 sequestration in the region.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
