CTV VI

Carbon TerraVault VI is a proposed multi-source carbon capture and sequestration "hub" in the northern San Joaquin Basin in western Fresno County, California. CTV plans to operate 7 Class VI CO₂ injection wells, plus monitoring wells and surface facilities, to store anthropogenic CO₂ from industrial sources across the basin together with potential direct air capture volumes, at an average rate of 3.38 MMT per year over 30 years for a total of 101.5 MMT. The Injection Zone comprises four stacked sandstone reservoirs separated by interbedded shales: Domengine at a mean depth of ~4,540 ft TVD (~1,190 ft thick, 31% porosity, 145 mD), Garzas at ~6,000 ft TVD (~1,220 ft, 29%, 106 mD), Blewett at ~7,990 ft TVD (~790 ft, 26%, 85 mD), and Tracy at ~9,230 ft TVD (~290 ft, 23%, 23 mD), with total injection depths spanning roughly 4,300 to 9,280 ft TVDSS. The primary Confining Zone is the Kreyenhagen Shale. Two injectate compositions are permitted, one representing DAC, blue hydrogen, or post-combustion capture and one representing biofuel or refinery capture, both maintained as dry supercritical CO₂ at the wellhead.
