Enhanced geothermal systems (EGS): A review

Renewable and Sustainable Energy Reviews, 2016
Abstract Geothermal energy is a renewable energy source that can be found in abundance on our planet. Only a small fraction of it is currently converted to electrical power, though in recent years installed geothermal capacity has increased considerably all over the world.

Efficient workflow for simulation of multifractured enhanced geothermal systems (EGS)

Renewable Energy, 2019
Abstract The increasing demand for clean energy with minimum environmental impact motivates development of geothermal energy. Simulating a geothermal reservoir is complex and time consuming, mainly because of the systems spatial and temporal non-isothermal nature and the enormous size of the domain/reservoir. Simulations become even more complex when

Experimental Evaluation of Flow Heterogeneity in Enhanced Geothermal Systems (EGS)

57th U.S. Rock Mechanics/Geomechanics Symposium, 2023
ABSTRACT Enhanced Geothermal Systems (EGS) are unconventional reservoirs with significant stored thermal energy and low hydraulic connectivity e.g., Hot Dry Rocks. To take advantage of these resources as a sustainable option, it is necessary to create and/or enhance existing fractures to achieve economic production ...

Deep Learning Based Production Prediction for an Enhanced Geothermal System (EGS)

SPE Canadian Energy Technology Conference and Exhibition, 2023
Abstract Hot dry rock (HDR) is a low-carbon geothermal resource and can be an alternative to fossil fuels. The prediction of sequential production is essential for operating a sustainable geothermal system, but its prediction using the numerical simulation method is time-consuming. Deep learning provides an alternative way for this task.

Evaluation of geothermal energy extraction in Enhanced Geothermal System (EGS) with multiple fracturing horizontal wells (MFHW)

Renewable Energy, 2020
Abstract The deep geothermal energy produced from Enhanced Geothermal System (EGS) has a great development prospect because of enormous potential and environmental friendliness. EGS process involves a complex thermal-hydraulic process, and fractures in EGS are main channels for fluid flow and heat transfer, the understanding of which is crucial to ...

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 ...
