Performance of enhanced geothermal system (EGS) in fractured geothermal reservoirs with CO2 as working fluid

Applied Thermal Engineering, 2019
Abstract Creating an open, connected fracture by hydraulic stimulation is vital to heat mining in an enhanced geothermal system (EGS). The existence of natural fractures, which seriously affects the development pattern, can complicate the hydraulic fractures.

Pairing Integrated Gasification and Enhanced Geothermal Systems (EGS) in Semiarid Environments

Energy & Fuels, 2012
We explore the feasibility of combining the circulation of supercritical CO2 in EGS reservoirs with integrated gasification combined cycle (IGCC) power generation. The symbiotic benefits of this pairing increase net power output over the use of either system in isolation, reduces water use per MWe, and substantially reduces fugitive emissions over ...

Enhanced Geothermal Systems (EGS): Hydraulic fracturing in a thermo-poroelastic framework

Journal of Petroleum Science and Engineering, 2016
Abstract The natural permeability of geothermal reservoirs is typically low and therefore needs to be enhanced to enable efficient use and economic viability. Hydraulic Fracturing (HF) methods, often referred to as hydraulic stimulation, are one of the primary methods used for permeability enhancement.

Stabilization of Forced Heat Convection: Applications to Enhanced Geothermal Systems (EGS)

Transport in Porous Media, 2016
The natural permeability of geothermal reservoirs is low and needs to be enhanced to ensure an efficient use and economic viability. Next to chemical enhancement, the main technique used for that purpose is hydraulic fracturing. Here, hydraulic fracturing is introduced in a thermo-poroelastic framework.

Characterization of a Fracture-Controlled Enhanced Geothermal System (EGS) in the Trans-Mexican-Volcanic-Belt (TMVB): Predictive Mechanical Model for Fracture Stimulation in an Enhanced Geothermal System Context (EGS)

2020
In 2020, as the world Energy demand keeps on rising (International Energy Agency (IEA), 2019), and with the global climate warming a reality (The Organisation for Economic Co-operation and Development (OECD), 2020), reducing our societal impact on Earth is of utmost importance. Energy and Climate have always been intrinsically related.

Deep Learning Assisted Optimization Workflow for Enhanced Geothermal Systems (EGS)

2023
The energy retrieval process in an Enhanced Geothermal System (EGS) depends on fracture networks to facilitate fluid movement, thereby enabling the extraction of heat from adjacent rocks matrix. Nonetheless, due to the inherent heterogeneity and intricate multi-physics characteristics of these systems, high-fidelity physics-based forward simulations ...

Thermal Stability of Aqueous Foams for Potential Application in Enhanced Geothermal Systems (EGS)

2022
Traditionally geothermal energy utilizes naturally occurring steam or hot water trapped in permeable rock formations through naturally occurring extraction wells or by implementing the hydraulic fracturing process by fracturing rock formations with water-based fracturing fluids.
