The National Carbon Sequestration Database and Geographic Information System (NATCARB) Saline
spatial database is a small-scale (large-area) overview of carbon dioxide (CO2) geologic storage potential in
saline formations across the USA and parts of Canada. Saline formations are composed of brine-saturated
porous rock and capped by one or more regionally extensive, low-permeability rock formations.Only saline
formations containing formation fluid with total dissolved solids (TDS) greater than 10,000 ppm merited
evaluation for potential CO2 storage. A saline storage resource can include one named geologic stratigraphic
unit or be defined as only a part of a stratigraphic unit.This data layer reflects the best available knowledge
regarding the location of carbon sequestration potential in the USA and Canada, both onshore and offshore.
