Onshore Oil & Gas: Development of a Soil-Gas Monitoring Protocol for Assessing the Integrity of Decommissioned Wells

This project focuses on the use of soil-gas measurements to infer the integrity status of decommissioned onshore oil and gas wells in England. The integrity of buried decommissioned wells may be impaired by long-term degradation of well materials and seals, so that fugitive gas may be released through the overlying soil. Previous studies have measured soil-gas to try and infer integrity, but the measurements and inferences have been variable - so the integrity status of decommissioned wells remains uncertain. This...
