Some geomechanical aspects of geological CO2 sequestration

KSCE Journal of Civil Engineering, 2009
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.

Carbon Dioxide Plume Evolution Following Injection into a Depleted Natural Gas Reservoir: Modeling of Conformance Uncertainty Reduction Over Time [PDF]

, 2019
The uncertainty in the long-term fate of CO2 injected for geologic carbon sequestration (GCS) is a significant barrier to the adoption of GCS as a greenhouse gas emission mitigation approach for industry and regulatory agencies alike.

Comparing carbon sequestration in an oil reservoir to sequestration in a brine formation-field study [PDF]

, 2008
Geologic sequestration of CO2 in an oil reservoir is generally considered a different class than sequestration in formations which contain only brine. In this paper, the significance and validity of this conceptualization is examined by comparing the ...

Using dendroclimatic analysis of exotic deciduous conifers in an arboretum to document tree growth in response to climate change, Northeast Ohio, USA

PLANTS, PEOPLE, PLANET, EarlyView.
Rising temperatures and wetter conditions in the Midcontinent of North America are influencing climate responses in trees. Dendroclimatological analyses of four exotic deciduous conifer species from Secrest Arboretum, Northeast Ohio help identify past, present and future climate‐tree interactions.

Nationwide cost and capacity estimates for sedimentary basin geothermal power and implications for geologic CO2 storage

Frontiers in Energy Research
Introduction: Sedimentary basins are naturally porous and permeable subsurface formations that underlie approximately half of the United States. In addition to being targets for geologic CO2 storage, these resources could supply geothermal power ...

Numerical Study on CO2-Brine-Rock Interaction of Enhanced Geothermal Systems with CO2 as Heat Transmission Fluid

MATEC Web of Conferences, 2016
Enhanced Geothermal Systems (EGS) with CO2 instead of water as heat transmission fluid is an attractive concept for both geothermal resources development and CO2 geological sequestration. Previous studies show that CO2 has lots of favorable properties as

Risk Assessment Scheme of CO2 Geologic Sequestration

Proceedings of the Symposium on Global Environment, 2005
Risk assessment of CO2 leakage from geologic sequestration sites is unavoidable for the implementation of the technology. However, the nature of the risk is different from well-known other toxic materials due to the complexity and uncertainty of the earth crust structures, long life time of CO2, and wide spatial distribution of leakage and its risk.

Artificial Neural Network Surrogate Modelling for Predicting and Optimising CO2 Conversion to Methanol Under Uncertainty

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT This study introduces a data‐driven surrogate modelling framework that combines an artificial neural network (ANN) with particle swarm optimisation (PSO) and a genetic algorithm (GA) to optimise methanol production under uncertain conditions.

Capacity investigation of brine-bearing sands of the Frio Formation for geologic sequestration of CO2 [PDF]

, 2001
The capacity of fluvial brine-bearing formations to sequester CO2 is investigated using numerical simulations of CO2 injection and storage. Capacity is defined as the volume fraction of the subsurface available for CO2 storage and is conceptualized as a ...

Carbon Farming Optimisation With Market Premiums for Biodiversity Co‐Benefits Under Climate Change Socio‐Economic Pathway Scenarios

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Achieving global climate change mitigation, biodiversity conservation and restoration goals requires innovative solutions that balance carbon sequestration with biodiversity conservation. Payments for ecosystem services markets often treat carbon sequestration and biodiversity separately, but integrating biodiversity as a co‐benefit within ...
