MS 3.11: fundamental aspects of geological storage of CO2

Oral 20 Minutes

The injection and storage of supercritical CO2 (scCO2) have been conducted in fractured sandstone reservoirs at In Salah, Algeria and Snøhvit, Norway, and planned in fractured sandstone, carbonate, and dolomite reservoirs at Longyearbyen, Norway, Hontomin, Spain, and Kevin Dome, USA, respectively, with matrix permeability varying from 0.01 to 60 md. For densely fractured reservoirs with low...

MS 3.11: fundamental aspects of geological storage of CO2

Oral 20 Minutes

Injection of CO2 deep underground into porous rocks, such as saline aquifers, appears to be a promising tool for reducing CO2 emissions and the consequent climate change. During this process CO2 displaces brine from individual pores and the sequence in which this happens determines the efficiency with which the rock is filled with CO2 at the large scale. The aim of this work is to better...

MS 3.11: fundamental aspects of geological storage of CO2

Oral 20 Minutes

We examine the linear and weakly nonlinear stability analyses of the dissolution-driven convection induced by the sequestration of carbon dioxide in a geological formation. The mathematical model consists of Darcy's equation, the conservation of mass and the conservation of solute equations. The model accounts for anisotropy in both carbon diffusion and permeability which is modeled by a...

345. Vertically-Integrated Dual-Continuum Models for CO2 Injection in Fractured Saline Aquifers

MS 3.11: fundamental aspects of geological storage of CO2

Oral 20 Minutes

Injection of CO2 into a saline aquifer leads to a two-phase flow system, including a supercritical CO2 phase and a brine phase. Various modeling approaches, including fully three-dimensional (3D) models and vertical-equilibrium (VE) models, have been used to study the system in unfractured formations. Three-dimensional models solve the governing flow equations in three spatial dimensions and...

379. Modification of wettability and interfacial tension by biosurfactant-producing bacteria for geologic carbon storage

MS 3.11: fundamental aspects of geological storage of CO2

Oral 20 Minutes

Injection of carbon dioxide (CO2) into deep geologic formations has been widely proposed as an effective way for the permanent storage of CO2. Modification of the interfacial properties of CO2 in minerals by using surfactant has been proposed aiming on increasing the mobility of CO2 through porous media. Surfactants are proven to effectively alter the interfacial tension and wettability in...

619. The impact of heterogeneity on the flow and trapping of CO2 in target UK aquifers

MS 3.11: fundamental aspects of geological storage of CO2

Oral 20 Minutes

The Bunter sandstone formation in the Southern North Sea and the Captain sandstone formation in the Northern North Sea represent two of the largest potential CO${}_2$ stores in the UK, with estimated capacities of up to 14 Gt and 1.7 Gt respectively [1, 2]. With current UK CO${}_2$ emission totalling ~400 Mt/yr [3], the Bunter and Captain formations alone have the potential to store UK emissions...

774. Adaptive hybrid multilayer model coupling vertically-integrated and full multi-dimensional models for geological CO2 storage

MS 3.11: fundamental aspects of geological storage of CO2

Oral 20 Minutes

CO${}_2$ injection into a saline aquifer leads to a two-phase flow system (supercritical CO${}_2$ and brine), which often involves large spatial and temporal scales that require high computational cost. To address the computational challenge, in the past decade, a series of simplified models based on vertical integration of the full multi-dimensional governing equations have been developed. These...

996. Quantitative measurements of partial saturations in Brine-CO2 saturated Rocks at pore scale

MS 3.11: fundamental aspects of geological storage of CO2

Oral 20 Minutes

Understanding the relation between CO2 saturation/distribution and velocity/attenuation of acoustic wave propagation is fundamental for an accurate and reliable quantitative interpretation of (seismic) CO2 monitoring data.

Quantitative interpretation of geophysical data requires understanding of the relationship between the physical properties of the rock, the microstructure of the rock, and...
