研究室紹介
Professor Ki-Bok Min's research lab specializes in geomechanics, enhanced geothermal systems (EGS), and fractured rock mechanics, with a strong focus on hydraulic stimulation, microseismicity monitoring, and coupled hydro-mechanical modeling in deep crystalline rock formations. The lab investigates fracture propagation mechanisms, stress-dependent permeability, and fluid transport in engineered geothermal systems, using advanced numerical modeling and field data from the Pohang EGS site in Korea. Their work integrates experimental, observational, and computational approaches to improve the understanding of reservoir stimulation and long-term performance in low-permeability rock environments.

15The first hydraulic stimulation for enhanced geothermal system (EGS) development in Korea had been conducted in the PX-2 well of 4,348 m depth in Pohang EGS site from January 29th to February 20th, 2016. Treatment histories of injection rate, wellhead pressure and corresponding induced microseismicity data were obtained from the stimulation test upon 140 m long open hole section at the well bottom. Wellhead pressure was up to 89 MPa and considerable level of flow rate was attempted up to 47 L/se
We present key observations and analyses of the first and second stimulations conducted at the Pohang enhanced geothermal system (EGS) site in Korea in 2016. The first hydraulic stimulation was conducted in the PX-2 well of 4.3 km depth, with the maximum wellhead pressure of 89.2 MPa, the maximum injection rate of 46.8 L/s, and a total injected volume of 1970 m3. The first stimulation showed non-linear and reversible fracture-opening behavior with injection pressure increase. The stimulation mec
