Details

This project used 2 approaches to investigate the long-term integrity of decommissioned onshore oil and gas wells in England.

Firstly, factors related to integrity were used to categorise wells according to their long-term potential to stay sealed or to leak pollutants like methane (report SC190005/R1). Secondly, soil gas was monitored at 6 selected wells to check for any evidence of leaking methane, which might indicate integrity failure (report SC190005/R2).
