Injection Wells: The Poison Beneath Us
There are more than 680,000 underground waste and injection wells nationwide, more than 150,000 of which shoot industrial fluids thousands of feet below the surface. Scientists and federal regulators acknowledge they do not know how many of the sites are leaking. But...Identification of Wells with High CO2-Leakage Potential in Mature Oil Fields Developed for CO2-Enhanced Oil Recovery
The work presented here focuses on the potential for leakage to occur from the deep regions of a wellbore, particularly from viable oil reservoirs. The potential for wellbore leakage where CO2 enhanced oil recovery or sequestration is or may be conducted is...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...Follow Us
