Rice Ranch Methane Abatement Project

Guardian Plug & Abandonment, LLC (Guardian) plugged four wells on a single wellpad in Denton County, Texas. This prevented future methane leakage of over 560,000 tCO2e. Guardian worked with EagleRidge Operating to plug four wells from one pad in Denton County, Texas. Two of these wells were made idle several years ago, and the other two were made idle in June 2024 with the Texas Railroad Commission. These were horizontal wells that produced gas from the Barnett Shale since 2010. They were plugged to avoid current and 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 their last months of production, these wells were producing between 90 and 190 thousand cubic feet per day of natural gas, at which point they were made idle due to economic unfavourability. In total, over 560,000 tons of CO2e were avoided by successfully and permanently plugging and abandoning these wells.
