Evolution History of the Kakkonda Magma-hydrothermal System, Japan, Estimated through Simplified-model Numerical Simulatlons
At the Kakkonb geothermal area, Japan, a large Quaternary granitic body is dstributed below ca 2.5 km ckpth from the surface, associating with thick high-temperature contact me&amorphic zones in the overlying formations, and a meteoric-water-cbminated type hydrothermal system is developedat present time. During the 'Deep-seated Geothermal Resources Survey', WD-la well was drilled to 3729 m dept...

Heating in a Geothermal Reservoir
A computer program in Visual Basic 6.0 is written to calculate steam tables for pure water up to 800oC and 1400 bar. The steam tables are created as a DLL (Dynamic Link Library) object with properties: temperature, pressure, specific volume, enthalpy and entropy for liquid and vapor phases, and liquidvapor state. The steam tables can be incorporated in any computer program on the Windows platfo...
متن کاملReview of Recent Development of the Kakkonda Deep Reservoi.r, Japan
There are two reservoirs with different temperature and permeability in the Kakkonda hydrothermal system. The shallow reservoir is permeable and 230 to 2 6 0 T , while the deep reservoir is less permeable and 350 to 3 6 0 T . However, they are hydraulically connected each other. Recent drilling of deep wells revealed existence of PreTertiary formation below Tertiary formations and neogranitic p...
