An Evaluation of Rock Integrity and Fault Reactivation in the Cap Rock and Reservoir Rock Due to Pressure Variations
Cap rocks are dams which can prevent the upward movement of hydrocarbons. They have disparities and weaknesses including discontinuities, crushed areas, and faults. Gas injection is an effective mechanism for oil recovery and pore pressure. With increasing pore pressure, normal stress is reduced, and the integrity of impermeable boundaries (cap rock, fault, etc.) becomes instable. A successful ...
متن کاملExperimental evaluation of in situ CO2-water-rock reactions during CO2 injection in basaltic rocks: Implications for geological CO2 sequestration
[1] Deep aquifers are potential long-term storage sites for anthropogenic CO2 emissions. The retention time and environmental safety of the injected CO2 depend on geologic and physical factors and on the chemical reactions between the CO2, the aquifer water, and the host rocks. The pH buffer capacity of the aquifer water and the acid neutralization potential of the host rocks are important fact...
متن کاملMineral carbonation in peridotite rock for CO2 sequestration and a method of leakage reduction of CO2 in the rock
In the recent years, the amounts of green house gases have dramatically increased. This situation led to changing in climate conditions. One of the effective ways to reduce these amounts in atmosphere is CO2 capturing from huge spreading sources and injection it into geological formations. Peridotite is a type of rock that reacts with CO2 at higher rate when compared to the other rocks. Since t...
متن کاملGeological Sequestration of CO2: Mechanisms and Kinetics of CO2 Reactions in Mafic and Ultramafic Rock Formations
The main purpose of this exploratory project is to develop a more fundamental understanding of the long-term sequestration of CO2 via mineral carbonation reactions involving the common Mg-silicates in serpentinite and basalt mineral assemblages. Past experimental studies have shown that these reactions are kinetically limited, so we are exploring ways to enhance their kinetics, including the us...
متن کاملGeological Sequestration of CO2: Mechanisms and Kinetics of CO2 Reactions in Mafic and Ultramafic Rock Formations
We investigated the interactions between CO2-rich fluids and Mg-silicate minerals using experiments to provide information on reaction rates and to identify potential catalysts for the reactions, and studies of natural analogues to assess the conditions that lead to massive carbonation of ultramafic rocks and thus the potential for field-scale implementation. Key findings from our exploratory w...
