Milestone CO2 Slurry Injection

Under Development

Project Operator: Milestone Environmental Services

Team: Carolina Ortega

Location: 6605 FM1583, Dilley, TX 78017

Milestone operates the largest network of slurry injection facilities in the U.S., offering advanced sequestration solutions that permanently trap hydrocarbons from our customers' waste a mile beneath the Earth’s surface. This process prevents the hydrocarbons from volatilizing into the air as emissions, which would naturally occur if the waste were disposed of through traditional methods like reserve pits and landfarming. The reduction in emissions realized by using our waste sequestration technology significantly exceeds the emissions generated from our operational activities, providing a substantial net carbon benefit. Our proprietary process ensures compliance with regulations, and provides E&P companies with a robust solution to significantly reduce the risks of soil and groundwater contamination while lowering operational carbon footprints. Milestone enables energy companies to adopt a cleaner, more responsible approach to waste management. Milestone maintains a rigorous monitoring, reporting, and verification program to ensure a full accounting of carbon that is deposited into our Class II wellbores. We have conducted extensive sampling across our portfolio of assets to monitor and quantify the total petroleum hydrocarbon content, and are currently engaging with third-party independent carbon registry boards to develop our own methodology to undertake the project.
Expected Annual Credit Quantity
198,000
Project's Financial Additionality
Monetizing carbon credit revenue will ensure that these injection facilities stay economically viable and continue operations of nearly 200K TPA of emissions reductions. Additionally, carbon credit revenue can contribute to restarting currently nonviable sites to increase emission reductions.
Additionality
Capturing CO2 within the slurry stream is not currently mandated or a typical course of business for customers. The alternate way operators may look to dispose of waste would be via landfarming or reserve pits, where the existing regulatory requirements are quite low. Landfarming can produce up to 650 tons per hectare per year of CO2.
