Evaluation of the Potential for Gas and CO2 Leakage Along Wellbores
Leakage pathways may exist through and along wellbores, which may penetrate or be near to the storage site. An evaluation is the first step in determining what factors may contribute to wellbore leakage from CO2 storage sites.Why Oil Wells Leak: Cement Behavior and Long-Term Consequences
Oil and gas wells can develop gas leaks along the casing years after production has stopped and the well has been plugged and abandoned. Explanations include channeling, poor cake removal, shrinkage, and high cement permeability. The reason is probably cement...In Western Pennsylvania, an Energy Boom Not Visibly Stifled
