South Texas Sequestration Project

The South Texas Sequestration Project (Kleberg Hub), led by 1PointFive (a subsidiary of Occidental Petroleum through Oxy Low Carbon Ventures), is designed to demonstrate large-scale carbon capture and storage (CCS) along the Texas Gulf Coast. The project is located in Kleberg County, Texas, where six Class VI injection wells (Becerra and Garcias sites) are proposed under EPA permit R06-TX-0015. It will permanently sequester industrial CO₂ captured from Gulf Coast emitters, with an expected injection rate of several million metric tons annually over multiple decades. The site covers approximately 106,000 acres under lease agreements with Kind Ranch, securing pore space, surface access, and land rights needed for storage. Extensive geologic characterization has identified stacked Oligocene-age sandstones as high-quality injection targets with multiple overlying confining shales to ensure containment. Data from three stratigraphic test wells drilled in 2023 confirmed porosity, permeability, and sealing capacity, and these results were incorporated into reservoir and plume modeling. The site sits in a low-fault, low-seismicity area of the Rio Grande Embayment, with risk assessments indicating low likelihood of induced seismicity under planned injection pressures.
