General Information About Injection Wells | US EPA
2024年7月10日 · Class VI wells are wells used for injection of carbon dioxide (CO2) into underground subsurface rock formations for long-term storage, or geologic sequestration. UIC regulations mandate the consideration of a variety of measures to assure that injection activities will not endanger underground sources of drinking water (USDWs).
Class VI - Wells used for Geologic Sequestration of Carbon Dioxide
2024年12月11日 · Class VI wells are used to inject carbon dioxide (CO2) into deep rock formations. This long-term underground storage is called geologic sequestration (GS). Geologic sequestration, as part of carbon capture and storage (CCS), is a technology that can be used to reduce CO2 emissions to the atmosphere and mitigate climate change.
Well completion and integrity evaluation for CO2 injection wells
2015年5月1日 · This paper introduces the basic challenges of designing a CO 2 injection well, reviews the famous CO 2 injection cases around the world, and proposes well completion criteria, including completion scheme design, materials selection and so on. Well integrity tests in use are reviewed and evaluated in terms of their pros and cons.
Design of Carbon Capture and Sequestration CCS Wells
2022年3月1日 · This paper discusses a methodology for the design of wells in carbon capture and sequestration (CCS) projects. In addition to carbon dioxide (CO 2) injection wells, CCS wells include observation or monitoring wells, as well as utility wells, which are used to reduce pressure by removing formation water.
Underground Injection Control Well Classes | US EPA
2024年4月1日 · Class VI wells are wells used for injection of carbon dioxide (CO2) into underground subsurface rock formations for long-term storage, or geologic sequestration. UIC regulations mandate the consideration of a variety of measures to assure that injection activities will not endanger underground sources of drinking water (USDWs).
Class VI - Wells used for Geologic Sequestration of CO2
2016年10月6日 · Class VI wells are used to inject carbon dioxide (CO2) into deep rock formations. This long-term underground storage is called geologic sequestration (GS). Geologic sequestration refers to technologies to reduce CO2 emissions to the …
Well Engineering and Injection Regularity in CO₂ Storage Wells
2018年11月1日 · Industry experience with CO₂ EOR wells (both for CO₂ continuous injection as well as for CO₂-WAG) shows that new CO₂ injection wells can be suitably designed to allow well integrity to be maintained in the long-term. Concerns from cement degradation and corrosion can be suitably addressed in the design and construction of these wells.
Carbon sequestration wells will swell from a few to more than 40
2024年1月19日 · For all the talk of carbon dioxide sequestration, not many sites today are injecting CO2 underground for permanent storage. That’s likely to change in 2024 as the US Environmental Protection Agency and other government bodies around the world approve a raft of permits for project developers eager to start storing CO2.
Well Integrity and Well Control evaluation for CO2 Injection Wells…
Well integrity and well control evaluation is a vital process that underpins the safe and efficient operation of CO 2 subsurface injection wells. By focusing on well design, re-use of existing infrastructure, well integrity, quality well elements, and stringent well control practices, operators can minimize the risks associated with CO 2 ...
Carbon dioxide (CO2) injection processes and technology
2010年1月1日 · An appropriately designed and constructed well would help to enhance CO 2 injectivity in geological formations, prevent endangerment to the environment and would maintain integrity throughout the lifetime of the project, from the injection operation period through and beyond the post-injection site care period once the well is permanently ...
