Environmental Risk Arising From Well-Construction Failure – Differences Between Barrier and Well Failure, and Estimates of Failure Frequency Across Common Well Types, Locations, and Well Age
This paper will show the great majority of wells do not pollute. The purpose of this paper is to explain basic concepts of well construction and illustrate differences between single-barrier failure in multiple- barrier well design and outright well-integrity failure...Possible indicators for CO2 leakage along wells
A preliminary analysis of this information indicates that 4.6% of these wells have recorded surface casing vent flow or gas migration through wellbore annuli or outside casing. Data analysis shows that there is a correlation between these occurrences and economic...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...Follow Us
