| Abstract |
More than twenty years have passed since geothermal research and drilling took place at the geothermal fields in Nicaragua- The well known Momotombo Geothermal Field (70 We) has been generating electricity since 1983, and now a new geothermal field is under exploration. The San Jacinto-Tizate. 'itvo reservoirs hydraulic connected were found. The shallow reservoir (270?C) at the depth of 550 - 1200 meters, and the deep one at > 1600 meters. Both of theme are water dominated reservoirs, although a two phase condition exist in the upper part of the shallow one. Different trisient tests and a mutti-well interference test have been carried out, very high transmissivity value were estimated around the well SJ-d and average values for the others. A preliminar conceptual model of the geothermal system is given in this paper, as the result of the geology, geophysics, hydrology studies, drilling and reservoir evaluation. |
