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 کاملPrecise Gravimetry and Geothermal Reservoir Management
Modern portable gravimeters can routinely achieve a 5 ugal uncertainty with careful measurement procedures involving multiple station occupations in the same day, and stacking of readings over at least 15 minutes during each occupation. Although further improvements in gravimeter accuracy are feasible, other practical factors relating to repeat surveys of geothermal fields make such improvement...
متن کاملFracture Network Modeling of a Hot Dry Rock Geothermal Reservoir
Fluid flow and tracer transport in a fractured Bot Dry Rock (HDR) geothermal reservoir are modeled using fracture network modeling techniques. The steady state pressure and flow fields are solved for a two-dimensional, interconnected network of fractures with no-flow outer boundaries and constant-pressure source and sink points to simulate wellbore-fracture intersections. The tracer response is...
متن کاملSteam-water Relative Permeabilities for the Cerro Prieto Geothermal Reservoir
We have refined a method used previously by several authors to estimate water-steam relative permeabilities. Our version provides also reasonable estimates of the corresponding saturations. It relies on production output data obtained by means of short tests. This constitutes a distinct advantage over the previous variants, which require long-term production data, because it allows early accura...
متن کاملInvestigation of Salt Precipitation in Geothermal Reservoir near Sealing Conditions
The main goal of the work is to investigate the behavior of a geothermal reservoir containing salty water when its physical parameters exceed the critical values, i.e. when the vaporization process cannot be described by the asymptotic self-similarity solution. We consider a low-permeability rock, where salty water vaporizes at a sharp front, because of fluid extraction at constant pressure. If...
