Project Title:
Geothermal Resource Assessment in Mahallat Geothermal
Region
Department: Renewable Energies
Employer: Renewable Organization of Iran (SUNA)
Project Manager: Javad Nouraliee
Project Code: JNENE09
Project Summary:
In 2000, Renewable Organization of Iran (SUNA) had conducted a nation-wide
geothermal resource assessment through the whole Iran territory.
Based on resource assessment 14 geothermal regions have been recognized including
Mahallat geothermal regions (MGR). MGR has 51,000 Km 2 and covers Qom, Markazi
and Isfahan provinces. Due to the large size of MGR economically it isn't recommended
to design and perform a detailed exploration program about it. So, initially it is advised
to execute a more detailed resource assessment in MGR to find much smaller prospects.
In fact they are small enough to conduct a detailed exploration prograM.
In order to recognize geothermal prospects in MGR the following studies were
performed:
1. Library research
2. Research on available geological maps
3. Study of water regional companies data of Qom, Markazi and Isfahan provinces
4. Aeromagnetic Surveying
5. Remote sensing Study
6. Integrated interpretation of all obtained data
Finally 22 geothermal prospects were found in MGR. Among them Khorhe and Vartun
prospects have include warm springs.
Khorhe prospect is located in north-east of Mahallat city and its area is 197 Km 2 .
Geothermometery studies reveal that Khorhe geothermal reservoir temperature is 54-
146 °C. There are 6 warm springs in Khorhe prospect which their temperature varies
from 33 to 48 °C. Stored thermal energy in Khorhe prospect is estimated 7.4 × 10 16 Kj.
Vartun prospect is located in north-east of Isfahan city and its area is 277 Km 2 .
Geothermometery studies reveal that Vartun geothermal reservoir temperature is 46-182
°C. There are 3 warm springs in Vartun prospect which their temperature varies from
45.5 to 43 °C. Stored thermal energy in Vartun prospect is estimated 1.14 × 10 17 Kj.
