Some Geomechanical Aspects of Geological CO2 Sequestration
Reservoir depletion and subsequent CO2 injection into the depleted geological reservoir induce stress changes that may mechanically damage top seal and wells, or trigger existing faults, creating the leakage pathways for CO2 escape from the reservoir. The role of geomechanics is to assess the mechanical impact of stress changes on seals, wells and faults. Since many hydrocarbon fields are geome...
متن کاملA Model for Flood Basalt Vulcanism
The question of whether basaltic rocks in continental flood basalt provinces are primary magmas or whether they are descended in general from picritic parent magmas is reviewed. It is suggested that the latter is more likely to be correct on the evidence of phase relations and the relative rareness of mantle materials with appropriate Fe/Mg ratios. Major element variations in the residual liqui...
متن کاملCarbon dioxide sequestration in deep-sea basalt.
Developing a method for secure sequestration of anthropogenic carbon dioxide in geological formations is one of our most pressing global scientific problems. Injection into deep-sea basalt formations provides unique and significant advantages over other potential geological storage options, including (i) vast reservoir capacities sufficient to accommodate centuries-long U.S. production of fossi...
متن کاملGas - Water - Rock Interactions Induced by Reservoir Exploitation , CO 2 Sequestration , and Other Geological Storage *
At the opening of the Millenium the planet Earth is confronted with a major open question, namely: what will be the result in the nearby future of the soaring interference between human activities and natural environmental processes? There is an increasing sense of alarm about the anthropogenic threats that exert pressure on the environment, especially if projected towards the future with the g...
متن کاملSemianalytical Solution for $$ \text{ CO}_{2}$$ Plume Shape and Pressure Evolution During $$ \text{ CO}_{2}$$ Injection in Deep Saline Formations
The injection of supercritical carbon dioxide (CO2) in deep saline aquifers leads to the formation of a CO2 rich phase plume that tends to float over the resident brine. As pressure builds up, CO2 density will increase because of its high compressibility. Current analytical solutions do not account for CO2 compressibility and consider a volumetric injection rate that is uniformly distributed al...
