Analysis of CO2 Migration in Horizontal Saline Aquifers during Carbon Capture and Storage Process

CO2 Storage in Saline Aquifers

CO2 Storage in Saline Aquifers — Saline aquifers represent a promising way for CO2 sequestration. Storage capacities of saline aquifers are very important around the world. The Sleipner site in the North Sea is currently the single case world-wide of CO2 storage in a saline aquifer. A general review is given on the specific risks for CO2 storage in saline aquifer. The regional distribution of C...

Analytical Modeling of CO2 Migration in Saline Aquifers for Geological CO2 Storage

Injection of carbon dioxide into geological formations for long-term storage is widely regarded as a promising tool for reducing global atmospheric CO2 emissions. Given the environmental and health risks associated with leakage of CO2 from such a storage site, it is critical to ensure that injected CO2 remain trapped underground for the foreseeable future. Careful site selection and effective i...

Reservoir Simulation of CO2 Storage in Deep Saline Aquifers

We present the results of compositional reservoir simulation of a prototypical CO2 sequestration project in a deep saline aquifer. The objective was to better understand and quantify estimates of the most important CO2 storage mechanisms under realistic physical conditions. Simulations of a few decades of CO2 injection followed by 10 to 10 years of natural gradient flow were done. The impact of...

How pressure buildup and CO2 migration can both constrain storage capacity in deep saline aquifers

A promising way to mitigate global warming is to sequester CO2 in deep saline aquifers. In order to determine which aquifers are the best for sequestration, it is helpful to estimate how much CO2 they can store. Currently, this is difficult because both the pressure buildup from injection and the volume of available pore space have been identified as constraints, but have not been compared to d...
