4. GEOTHERMAL ENERGY POTENTIAL
Preliminary study of hot springs in Thailand predicts that hot springs in northern Thailand are classified as medium
enthalpy while the others are low enthalpy. Geothermal study of 50 hot springs in northern Thailand based on utility
classification divided into 5 categories. Very high geothermal potential yields reservoir temperature higher than 180 °C
with suitable reservoir structure at rather shallow depth, has 5 fields. High geothermal potential yields reservoir temperature
between 140-180 °C, provides suitable reservoir structure, has 17 fields. Moderately high geothermal potential yields
reservoir at high temperature but provides limited or restricted reservoir structure, has 4 fields. The other geothermal fields
are classified as low geothermal potential and undetermined geothermal potential
