Carbon sequestration potential of the Habanero reservoir when carbon dioxide is used as the heat exchange fluid

Journal of Rock Mechanics and Geotechnical Engineering, 2016
The use of sequestered carbon dioxide (CO2) as the heat exchange fluid in enhanced geothermal system (EGS) has significant potential to increase their productivity, contribute further to reducing carbon emissions and increase the economic viability of ...

Prospects for Assessing Enhanced Geothermal System (EGS) Basement Rock Flow Stimulation by Wellbore Temperature Data [PDF]

, 2017
We use Matlab 3D finite element fluid flow/transport modelling to simulate localized wellbore temperature events of order 0.05–0.1 °C logged in Fennoscandia basement rock at ~1.5 km depths.

Caving‐enhanced geothermal system overwhelms fracturing‐ and pipe‐enhanced geothermal system in heat extraction

Deep Underground Science and Engineering, EarlyView.
Our study reveals that caving‐enhanced geothermal systems (C‐EGS) with adequately fractured reservoirs achieve optimal heat extraction by minimizing preferential flow paths, while conventional fracturing (F‐EGS) and pipe‐based (P‐EGS) systems suffer accelerated thermal drawdown.

Theoretical Maximum and Cumulative Seismic Moment Relationships Confirm that Injection Volume Controls the Occurrence Rate, But Not the Magnitude, of Induced Earthquakes

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Classical relationships between cumulative and maximum seismic moment, based on the Gutenberg‐Richter law, shows a non‐physical anomaly for low b‐values. We here derive new relationships, including a low and a high b‐value approximation.
