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.
