Numerical Modeling of a Desaturating Geothermal Reservoir
Numerical Heat Transfer, Part B: Fundamentals, 1978Abstract To achieve a better understanding of hot-water geothermal reservoirs, the problem of a hypothetical geothermal aquifer that depletes the fluid saturating its upper regions during production is considered. This depletion leads to the characteristic depressurization and drawdown of the liquid surface observed typically at the Wairakei geothermal

Regional Geothermal 3D Modeling in Denmark
Proceedings, 2012We present first results of a 3D model of the subsurface temperature in Denmark. Updated temperatures are contoured for the Gassum formation which is currently utilized for geothermal energy production. The Gassum formation of Upper Triassic/Lower Jurassic age is present in most of Denmark with sufficient net sand thickness and temperatures between ...

Geothermal Reservoir Modelling
SPE Annual Fall Technical Conference and Exhibition, 1977Abstract This paper describes and partially evaluates an implicit, three-dimensional geothermal reservoir simulation model. The evaluation emphasizes stability or time-step tolerance of the implicit finite-difference formulation.

Numerical Modeling Of The Wairakei Geothermal Reservoir
SPE California Regional Meeting, 1977American Institute of Mining, Metallurgical, and Petroleum Engineers, Inc. Abstract In order to achieve a better understanding of the Wairakei geothermal reservoir and of others of similar type, the current investigation considers the problem of a hypothetical geothermal aquifer that depletes the ...

Modeling a Geothermal Field in Japan
IEEE Power Engineering Review, 1986Studied is a three-dimensional simulator of single-phase, hot-water flow which consists of fracture-type flow and recharge from the ground surface. Equations as applied to the simulator, and some assumptions and methods of solution are also described. These are applied to modeling of a geothermal field where exploration on geothermal activity is being ...

Development Model for Geothermal Reservoirs
Proceedings of SPE California Regional Meeting, 1986Abstract The deliverability of liquid-dominated geothermal reservoirs is presented in terms of reservoir performance, inflow performance, and wellbore performance. Water influx modeling is used to match the performance of Wairakei in New Zealand, and Ahuachapan in El Salvador.

Stock models for geothermal resources
Geothermics, 2018Abstract Stock models are useful for quantifying geothermal resources with a focus on important large-scale reservoir characteristics such as energy content, well deliverability and recharge into geothermal systems. Stock models have the benefit of being dynamic, although they do not require much more input than the volumetric models used commonly in

1989
In Chapter 1 the origin of the heat of the Earth has been discussed and it is now possible to proceed to examine localized accumulations, that is to say geothermal systems. The word ‘geothermal’ refers to the thermal energy of the planetary interior and it is usually associated with the concept of systems in which there is a large enough reservoir of ...

A model of the Kakkonda geothermal reservoir
Geothermics, 1995Abstract Reservoir pressures, temperatures and chloride concentrations are interpreted from well measurements in the Kakkonda geothermal field (Japan), to obtain a natural state conceptual model and to determine changes in the reservoir subsequent to production and reinjection. In this model the system is viewed as two reservoirs, a shallow reservoir

Geothermal models for the East Carpathians
Tectonophysics, 1984Abstract In order to explain the high heat flow (73–126 mW m −2 ) observed at the inner part of the East Carpathians, a model which takes into account the radiogenic heat generation and the descent of a lithospheric plate has been elaborated. Calculated geotherms indicate the presence of a high temperature anomaly (exceeding 1000°C) localized in the ...
