Carlton Methane Abatement Project

In this project, Guardian Plug & Abandonment, LLC (Guardian) is plugging two wells in Ellis County, Texas. This will prevent future methane leakage of 803,104 tCO2e. Guardian worked with EagleRidge Operating to plug two wells from one pad in Ellis County, Texas. One of the wells was idle for several years, and the other was made idle in June 2024 with the Texas Railroad Commission. These were horizontal wells that produced gas from the Barnett Shale since 2010. These wells were plugged to avoid future methane gas emissions. Cast iron bridge plugs and multiple cement plugs were placed in each wellbore to permanently seal off emissions sources. The surface of the site was cleared of all equipment and cleaned up. In the last months of production, each of the wells were producing natural gas at rates around 300 thousand cubic feet per day, at which point they were made idle due to economic unfavourability. In total, over 800,000 tons of CO2e emissions were avoided by successfully and permanently plugging and abandoning these wells.
