Parametric Study of Energetic Simulation for Geothermal Applications

摘要

We present results from a study investigating the effectiveness of energetic stimulation as applied to a geological setting relevant to geothermal applications requiring stimulation. Our results confirm that detonations may be used to stimulate the rock more uniformly in the near field of the explosion. In addition, we observe synergistic interactions among multiple charges. However, these same results indicate that such mechanisms alone cannot stimulate the rock at the ranges away from the wellbore achievable via hydraulic fracturing. We also investigate the influence of bedding planes and natural fractures upon the energetic simulation process and determine that favorably oriented discontinuities can enhance the range of the stimulated zone.
