CO2 Storage in Carboniferous Formations and Abandoned Coal by Manchao He, Luis Ribeiro e Sousa, Derek Elsworth, Euripedes

By Manchao He, Luis Ribeiro e Sousa, Derek Elsworth, Euripedes Vargas Jr.

Underground geological garage of carbon dioxide (CO2) has huge power for mitigating weather swap. CO2 will be competently injected and kept at good characterised and correctly controlled websites. Injecting carbon dioxide in deep geological formations can shop it underground for lengthy classes of time. Depleted oil and gasoline reservoirs, saline aquifers and carboniferous formations can be utilized for garage of CO2, in addition to in deserted coal mines. At depths under approximately 800-1000m, CO2 has a liquid-like density that allows the effective use of underground reservoirs in porous sedimentary rocks.

The papers within the current quantity are from major specialists within the box of CO2 garage and have been offered at a global Workshop on CO2 garage in Carboniferous Formations and deserted Coal Mines (Beijing, China, 8-9 January 2011). CO2 garage in deserted coal mines seems to have a shiny destiny. even if CO2 garage in Carboniferous Formations and deserted Coal Mines is essentially meant for mining engineers, environmental engineers and engineering geologists, the e-book can be beneficial to civil engineers, and lecturers and execs in geophysics and geochemistry.

Distribution of CO2 industrial point sources in China (Li, 2009). indb 27 8/26/2011 10:07:46 AM Of these, about 50 large power plants located near coal mines and some abandoned mine, which provide adequate underground space for storage of CO2 emitted from coal-fired power generation.

In Salah gas project, Algeria (IPCC, 2005). depth of 1800 m. 2. The CO2 injection began in April 2004 and for the duration of the project; it is estimated to store about 17 MtCO2. The complex consists of four production wells and three injection wells (Figure 26). 5 km) are used to inject CO2 in the areas of the reservoir with high permeability. The Krechba field is a relatively simple anticline. The injected CO2 is expected to migrate into the area of the current gas field after depletion of the gas zone.
