Four major trapping mechanism have been identified: Structural and stratigraphic trapping is the containment of supercritical CO2 by low permeability / low porosity rocks and is the dominant mechanism during injection and initial storage phase. Residual or capillary trapping is the retention of supercritical CO2 in the pore space between grains and tends to be most relevant on a\nscale of tens to thousands of years. Solubility trapping is the uptake of CO2 into the formation water, which is considered to be the most important trapping mechanism over hundreds to millions of years (1).\nMineral trapping leads to the permanent immobilization of carbon through the precipitation of carbonate minerals.\n\nThis study assesses the conditions for solubility trapping in major Australian sedimentary basins. The total dissolved solid (TDS) concentration of the formation water has been compiled from over\n900 wells as it, along with pressure and temperature, is a key variable controlling CO2 solubility and the associated change in fluid density. Fluid density is a critical factor in driving fluid advection which determines the rate of solubility trapping and downward migration in the formation. This process is vital in reducing the amount of highly mobile supercritical CO2 at the top of the formation and storing it as dissolved CO2 in deeper parts of the formation.", "num_resources": 2, "num_tags": 6, "organization": {"id": "0143757a-86ab-43e4-bba6-4a3a2a02b6c4", "name": "australian-ocean-data-network", "title": "Australian Ocean Data Network", "type": "organization", "description": "Harvester for Australian Ocean Data Network", "image_url": "", "created": "2025-06-23T12:29:10.320926", "is_organization": true, "approval_status": "approved", "state": "active"}, "original_harvest_source": {"site_url": "https://catalogue.aodn.org.au", "href": "https://catalogue.aodn.org.au/geonetwork/srv/eng/csw/dataset/the-variability-in-formation-water-composition-and-its-implications-for-co2-storage-conditions7", "title": "Australian Oceans Data Network"}, "owner_org": "0143757a-86ab-43e4-bba6-4a3a2a02b6c4", "private": false, "promotion_level": "0", "spatial": "Australia", "state": "active", "temporal_coverage_from": "2018-04-20 06:11:49", "title": "The Variability in Formation Water Composition and its Implications for CO2 Storage Conditions", "type": "dataset", "unpublished": false, "url": null, "version": null, "resources": [{"cache_last_updated": null, "cache_url": null, "created": "2026-03-05T05:51:15.025456", "datastore_active": false, "datastore_contains_all_records_of_source_file": false, "description": "Download the file (pdf)", "format": "PDF", "hash": "", "id": "2791db69-7ca6-4ec9-9219-412e9a3ca002", "last_modified": null, "metadata_modified": "2026-03-05T05:51:15.018158", "mimetype": null, "mimetype_inner": null, "name": "Download the file (pdf)", "package_id": "27a74052-4232-4977-9e82-146ac7452a91", "position": 0, "resource_locator_function": "information", "resource_locator_protocol": "WWW:LINK-1.0-http--link", "resource_type": null, "size": null, "state": "active", "url": "https://d28rz98at9flks.cloudfront.net/72903/72903.pdf", "url_type": null, "zip_extract": false}, {"cache_last_updated": null, "cache_url": null, "created": "2026-03-05T05:51:15.025462", "datastore_active": false, "datastore_contains_all_records_of_source_file": false, "description": "", "format": "HTML", "hash": "", "id": "c41dc077-df9a-4cea-a154-7c6fdc42ce9d", "last_modified": null, "metadata_modified": "2026-03-05T05:51:15.018262", "mimetype": null, "mimetype_inner": null, "name": "Unnamed resource", "package_id": "27a74052-4232-4977-9e82-146ac7452a91", "position": 1, "resource_locator_function": "", "resource_locator_protocol": "", "resource_type": null, "size": null, "state": "active", "url": "http://www.abs.gov.au/ausstats/abs@.nsf/Latestproducts/1297.0Main%20Features32008?opendocument&tabname=Summary&prodno=1297.0&issue=2008&num=&view=", "url_type": null, "zip_extract": false}], "tags": [{"display_name": "Earth Sciences", "id": "40d58e59-cdeb-4021-9e5a-aae60edebdf5", "name": "Earth Sciences", "state": "active", "vocabulary_id": null}, {"display_name": "GA Publication", "id": "e62fc1f2-3d55-4d1e-bd88-116cd26bc3fd", "name": "GA Publication", "state": "active", "vocabulary_id": null}, {"display_name": "Poster/Image", "id": "9b863083-2eb7-4702-84f5-9b494204b273", "name": "Poster/Image", "state": "active", "vocabulary_id": null}, {"display_name": "Published_External", "id": "5178775c-8044-4b7f-881f-5428a4e2d925", "name": "Published_External", "state": "active", "vocabulary_id": null}, {"display_name": "carbon dioxide", "id": "d6214ec0-3261-4603-9f1b-e2dd1333f74e", "name": "carbon dioxide", "state": "active", "vocabulary_id": null}, {"display_name": "marine", "id": "a6936e69-b556-4789-a92a-26333af2cbe6", "name": "marine", "state": "active", "vocabulary_id": null}], "groups": [], "relationships_as_subject": [], "relationships_as_object": [], "extras": [{"key": "harvest_object_id", "value": "60c45c4f-8111-4a40-b880-ecebe5f34477"}, {"key": "harvest_source_id", "value": "a2216e59-91ec-48b1-83cc-d35d9f09fcec"}, {"key": "harvest_source_title", "value": "Australian Oceans Data Network"}]}}
