CO2 leakage through existing wells: current technology and regulations
Preexisting wells and well bores are high-permeability pathways through the crust, and as such present zones of elevated risk to CO2 storage projects. Although current well closure and abandonment technology appears sufficient to contain CO2 at most sites, individual wells may suffer from a variety of factors that limit their integrity, including improper cementation, improper plugging, overpre...
متن کاملUsing the Electromagnetic Method to Locate Abandoned Brine Wells in Hutchinson, Kansas
Natural gas explosions and fire destroyed two businesses in downtown Hutchinson and two residents of a mobile-home park also died of injuries from explosions. Gas geyser eruptions spewing a mixture of natural gas and saltwater in the area forced the evacuation of hundreds of people. The pathways to the land surface at both the explosion sites and the geysers were abandoned brine wells used for ...
متن کاملMulti-Objective Optimization of Monitoring Well Location for CO2 Leakage Detection in GCS
1. Abstract Capture and sequestration of CO2 in deep geological formations is an attractive option to reduce the amount of CO2 emissions into the atmosphere. The capture of CO2 is mostly done at large stationary point sources, such as power plants and refineries, and then it is injected in deep saline aquifers or old oil and gas fields. One of the environmental and policy concerns with this str...
متن کاملRisk assessment for future CO2 Sequestration Projects Based CO2 Enhanced Oil Recovery in the U.S
This paper is the first of a series that attempts to assess the possible health and safety risks associated with large scale CO2 sequestration in deep brine reservoirs. The approach is based on analysis of available data on the operational track record from CO2 transportation and injection associated with enhanced oil recovery (CO2-EOR) in the US. This paper is particularly concerned with ident...
