◆Geothermal reservoir analysis
Our research on geothermal development has high practical use to
overcome various problems and its field is extensive, such as research
from geothermal power generation using high temperature geothermal
fluids to geothermal utilization using the thermal energy near the land
surface. On the research for geothermal reservoir analysis we analyze
the data of geothermal fields in Kyushu or Tohoku district using
reservoir engineering approaches and are understanding of the hydraulic
characteristics of the reservoir by analyzing the results of the tracer
test and simulation.
・Reservoir simulation
・Tracer test
◆Geothermal production engineering
On the research for geothermal production engineering we analyze
the wellbore flow using simulation software .
・Wellbore Flow
◆Research on Geothermal Heat Pumps
Geothermal heat pump system is an energy supply system using
thermal resources of shallow ground. The wider application of this
system is expected to be the solution to environmental problems such as
the heat-island phenomenon or energy-savings. Recently we have varied
field tests at various locations in Japan for development of
cost-effective geothermal heat pump systems.
◆Modeling of Large-scale Groundwater Flow System
We construct numerical models to analyze large-scale groundwater
flow systems based on the water properties, stable isotope ratios of
oxygen and hydrogen and distribution of groundwater temperature, which
are obtained through extensive field surveys.
