Magnolia

The Magnolia Sequestration Project is a Class VI carbon storage development by Magnolia Sequestration Hub, LLC in southwest Louisiana. Four wells, Magnolia CCS-1 through CCS-4, inject CO2 into the Oligocene Frio sandstone, a saline reservoir averaging 30 percent porosity and 2,444 mD horizontal permeability. The Frio injection interval spans 4,982 to 6,994 feet with about 1,354 feet of net reservoir thickness, bounded above by the Anahuac and Lower Miocene confining zones and below by the Vicksburg. Injection targets the Frio in two intervals. CCS-1 and CCS-2 inject the Lower Frio (Frio 5 through 7); their twin wells CCS-3 and CCS-4 inject the Upper Frio (Frio 1 through 4). Each well follows a bottom-up recompletion sequence over a 15-year injection life, starting in the deepest sub-zone and moving up. Each well is constrained to 105 MMscfd, about 2.0 million tonnes per year or 5,476 tonnes per day.
