| Popis: | WOS: 000443168800020 Accessible resource base of the Simav Geothermal field, one of the high temperature field in western Anatolia, was estimated using the volumetric method together with Monte Carlo simulation. The main geothermal reservoir in the field hosted in metamorphic rocks having secondary permeability enhanced due to intense tectonic activity. The highest bottom-hole temperature at the field was recorded as 162.4 degrees C in the EJ-1 having depth of 725 m penetrating metamorphic rocks of Menderes Massif. At the application stage of the volumetric method physical parameters, such as area thickness, temperature, etc., related to geothermal reservoir were determined by Monte Carlo simulation in the context of probability density distributions. For this purpose, an Excel VB application that generates random values corresponding to the probability distribution for each parameter was created. Using a lognormal distribution for porosity and triangular distributions for reservoir thickness, area and temperature, the most likely accessible resource base of the Simav Geothermal Field was calculated as 1.3x10(15) kJ. The probability to achieve this value was calculated as 67%. The same simulation results the mean and the most likely electricity generation potential of Simav geothermal field as 26 MW and 19 MW, respectively. The probability of electrical generation capacity of 19 WM was calculated as 71%. Mass flow rate that should be supplied to the power plant of 19 MW was calculated as 1204 tones/hour (334 L/s). |
