Implication

Observational analysis reveals significant effects of triaxial stress on heat extraction efficiency in enhanced geothermal systems, suggesting improvement potential.

Key Points

Heat extraction efficiency varies with triaxial stress during cyclic injection—production in enhanced geothermal systems.
Experimental observations from flow rate and production temperature changes underline the significance of stress differences.
Analysis of production well capacity using naturally fractured granite provides insights into stress evolution effects.
Findings highlight the need to consider effective stress impacts on thermal response and fluid movement in geothermal energy extraction.
