CARBON SEQUESTRATION AROUND THE WORLD

Climate control and air pollution are global issues. As such, carbon sequestration is being researched and practiced around the world. During geological sequestration, carbon dioxide is injected into porous rock formations within the earth’s crust where it is trapped by overlying seals, or cap rocks. Target formations can include deep saline formations, active or depleted oil and gas reservoirs, and unminable coal seams.

Sedimentary basins have the greatest potential for carbon sequestration because they contain the thickest packets of targetable rock units. This map shows the distribution of sedimentary basins throughout the world.


Enhanced oil and gas recovery (EOR/EGR) is a type of geologic carbon sequestration in which CO₂ is pumped into active oil and gas reservoirs to stimulate production by increasing pressure in areas that will push more oil or gas toward the producing wells. This is a proven method and is currently carried out in various places around the world.
