| Summary: | We present a well-reservoir modeling study aimed at better understanding one of the hottest geothermal well ever drilled, the IDDP-2 well in Reykjanes. To obtain realistic models of the well and reservoir we follow three main steps. First, we simulate the evolution of the reservoir following the emplacement of a magmatic intrusion thousands of years ago to obtain the most likely natural state of the geothermal system. The simulations show that the reservoir permeability structure largely controls its thermal evolution. Model validation is done by refining the permeability structure and other secondary parameters until the simulation results match the currently measured reservoir temperatures along the well. An important constraint is the reservoir temperature of about 550 °C at 4500 m depth, consistent with previous estimates from geophysical inversions and fluid inclusions obtained in core samples from the deepest part of the well. Second, we constrain the location and permeability of the feed zones by ... : Geothermics, 114 ... |
