Various experiences on enhanced geothermal system (EGS) has been accumulated from the Soultz project through various scientific experiments and research activities for more than 20 years since it started in the year of 1984 until the 1.5 MW Organic Rankine Cycle (ORC) binary power plant has been built up in Soultz-sous-$\hat{e}$ area, France. They have been applied to Cooper basin in Australia, Landau and Insheim in Germany and so forth. This report summaries the experiences from Soultz in the aspect of artificial reservoir creation, expecting to be helpful for reducing any trial and errors or unnecessary expenses in ongoing Korean EGS project in Pohang area, where the geological features are similar to Soultz area.
