Geological Carbon Storage in Atlantic Canada Sedimentary Basins: Quantitative Screening, Play Elements and Risk Analysis
Bibliographic record
Abstract
Summary We present the first comprehensive quantitiative assessment and risking of geological carbon storage resources onshore and offshore Atlantic Canada (the provinces of Nova Scotia, Newfoundland and Labrador, Prince Edward Island and New Brunswick). On the continental margin, that extends 3800 km from the NE USA to northern Labrador, we build on 3 previous studies and assess storage in 54 hydrocarbon fields and deep saline aquifer systems in 12 Mesozoic-Cenozoic, rift-passive margin basins. We classify these resources under the SPE Storage Resources Management System. In the Gulf of St. Lawrence region we evaluate storage in Paleozic and Triassic sedimentary basins and risk these relative to Mesozic and Cenozoic aquifers in the Atlantic basins by aggregating Chance of Success in four play elements (storage, injectivity, containment and pressure space) and consolidating the results in a “traffic light” risk-adequacy matrix. There are no Atlantic Canada storage resources in the OGCI Carbon Storage Resource Catalogue, and investment is currently hampered by lack of offshore regulations and commercial terms.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
