Improvement in CO2 geo-sequestration in saline aquifers by viscosification: From molecular scale to core scale

Salar Afra et al.

Summary: An investigated CO2 oligomer viscosifier with twenty repeat units of 1-decene shows positive effects on flow control and sweep efficiency improvement in drainage. The viscosifier significantly increases the viscosity of supercritical CO2 and delays its breakthrough time. Additionally, it decreases the residual brine saturation and increases the residual trapping, leading to improved storage capacity and efficiency.

A Comprehensive Review of the Role of CO2 Foam EOR in the Reduction of Carbon Footprint in the Petroleum Industry

Ayomikun Bello et al.

Summary: By trapping and storing CO2 in geological formations, greenhouse gas emissions can be reduced. The use of anthropogenic CO2 for enhanced oil recovery can accelerate the development of CO2 storage technology and lower emissions from oil production. In situ foam generation is an effective method to reduce CO2 mobility in reservoirs.

Geochemical modelling of CO2 interactions with shale: Kinetics of mineral dissolution and precipitation on geological time scales

Ahmed Fatah et al.

Summary: The research suggests that shale formations are suitable geological targets for carbon dioxide storage. However, due to the high reactivity of shales to carbon dioxide, the sealing properties of shales need to be considered over geological time scales. The study constructed a simplified 1-D reactive transport model to investigate the mineralogical changes during carbon dioxide and brine interactions with shale. The model demonstrated that carbonate and clay minerals dissolved during the interaction, indicating the high potential of shales for carbon dioxide containment.

Assessing the potential of solubility trapping in unconfined aquifers for subsurface carbon storage

Mouadh Addassi et al.

Summary: To attenuate global warming, it is necessary to accelerate carbon capture and storage projects. This study evaluated the feasibility and limitations of injecting water-dissolved CO2 for subsurface solubility storage. The results suggest that unconfined aquifers could be a potential host for substantial subsurface CO2 storage.

Low-Temperature Synthesis of Disordered Dolomite and High-Magnesium Calcite in Ethanol-Water Solutions: The Solvation Effect and Implications

Yihang Fang et al.

Summary: Formation of dolomite [CaMg(CO3)(2)] has long been a mystery due to the challenges in synthesizing it at low temperatures. Recent experiments have shown that by partially replacing water with ethanol, high-Mg calcite and disordered dolomite can be precipitated at room temperature, bypassing the kinetic barriers caused by hydration shells. Increasing the volume percentage of ethanol can lead to higher Mg incorporation into the calcite structure, allowing for rapid precipitation of disordered dolomite. These findings suggest that ethanol synthesis experiments may provide insights into promoting high-Mg calcite precipitation in sedimentary and biomineral environments.

Quantification of mineral accessible surface area and flow-dependent fluid-mineral reactivity at the pore scale

Jin Ma et al.

Summary: The accessible surface areas (ASAs) of rock-forming minerals play a fundamental role in mineral reactivity with formation fluids, with efficiency varying significantly based on fluid chemistry and flow characteristics. A novel joint method for calculating ASAs of individual minerals in sandstone was developed and used to investigate the impact of flow rate on ASA efficiency during mineral dissolution reactions. The study found that dolomite reactivity increased with flow rate, reaching a relatively stable value, and compared two methods for analyzing experimental observations, highlighting the importance of careful consideration of flow rate when interpreting results.

CO2 geological sequestration in multiscale heterogeneous aquifers: Effects of heterogeneity, connectivity, impurity, and hysteresis

Reza Ershadnia et al.

Summary: By developing three-dimensional heterogeneous models based on field studies and considering the impact of various parameters on CO2 sequestration processes, this research reveals that increasing the volume proportion and connectivity of high-permeability facies enhances both adsorption and dissolution trapping of CO2. Neglecting relative permeability and capillary pressure hysteresis effects may lead to underestimation or overestimation of CO2 trapping capacities.

Summary: Methane emissions were measured at 6650 sites across six major oil and gas producing regions in Canada, showing variations by fluid type and geographic region. The estimate for Canada's upstream oil and gas methane inventory is underestimated by a factor of 1.5, particularly in heavy oil regions and in emission intensities for natural gas production.

Geochemical reactions and their effect on CO2 storage efficiency during the whole process of CO2 EOR and subsequent storage

Guodong Cui et al.

Summary: The study reveals that geochemical reactions have slight effects on reservoir properties during the CO2 enhanced oil recovery process, with most injected CO2 trapped as supercritical gas. In the stage of CO2 geological storage, supercritical CO2 converts into mineral form under the action of geochemical reactions, leading to reservoir pressure decrease. The water-alternating-gas (WAG) scheme is recommended for optimizing oil recovery and CO2 storage efficiency in the EOR process, while post-CO2 EOR injection can enhance storage capacity and maintain reservoir pressure stability.
