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...
متن کاملCO2 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...
متن کاملEffects of CO2 Compressibility on CO2 Storage in Deep Saline Aquifers
The injection of supercritical CO2 in deep saline aquifers leads to the formation of a CO2 plume that tends to float above the formation brine. As pressure builds up, CO2 properties, i.e. density and viscosity, can vary significantly. Current analytical solutions do not account for CO2 compressibility. In this article, we investigate numerically and analytically the effect of this variability o...
متن کاملPredicting PVT data for CO2–brine mixtures for black-oil simulation of CO2 geological storage
Accurate modeling of the storage or sequestration of CO2 injected into subsurface formations requires an accurate fluid model. This can be achieved using compositional reservoir simulations. However, sophisticated equations of state (EOS) approaches used in current compositional simulators are computationally expensive. It is advantageous and possible to use a simple, but accurate fluid model f...
متن کاملHow 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...
