More detials on CCS (Carbon Capture & Sequestration )

       

This video shows how carbon capture & sequestration work in the reality. The main body is the same as last blog I have wrote, but by watching this video you will easily understood the progress of CCS within minutes. We can see from the video that injecting the CO2 into oil fields, it tends to rise, as it is lighter than surrounding materials. But the cap rock prevented the CO2 of any further emission. The cap rock layer is impervious barrier that can keep CO2 underground forever. Over time, the CO2 will dissolve with oil remaining or salt water and then sink to the bottom of the layer. After thousands of years, the CO2 and naturally minerals react with each other and form stable minerals such as CaCO3. This process will help people prevent the re-entry of carbon back to natural cycle again. On the other hand, this video reveals the fact that when we injecting CO2 into oil fields, it can help us produce more undiscovered oil than before. And this oil recovery process may enhance the oil that might be recovered by 15%!!! There is monitoring process of the migration of CO2 in the subsurface that helps people find any leakage before, during and after injection of CO2.
