Pecan Island

The Pecan Island Class VI permit was submitted by ExxonMobil Low Carbon Solutions Onshore Storage LLC for two injection wells (Pecan Island Injection Wells No. 001 and 002) in Vermilion Parish, Louisiana, as the initial phase of ExxonMobil’s broader Pecan Island Area CCS Project. The application proposes permanent geologic sequestration of 3.2 million metric tons of CO₂ over the life of the two wells (1.6 MMTA per well), with long-term expansion potential to up to 10 MMTA. CO₂ would be sourced from industrial emitters including CF Industries and Nucor, transported via a combination of ExxonMobil- and EnLink Midstream-operated pipelines, and injected into thick, high-quality Miocene-age stacked sand–shale reservoirs characterized by favorable porosity, permeability, and confining seals.
