Geothermal Reservoir Modelling

SPE Annual Fall Technical Conference and Exhibition, 1977
Abstract 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.

ORIGIN OF STEAM IN GEOTHERMAL RESERVOIRS

Proceedings of SPE Annual Fall Technical Conference and Exhibition, 1977
Abstract In geothermal systems, due to the mechanism of mass and heat transport on the boiling point for depth curve, stable steam-water mixtures can occur only at reservoir pressures less than about 30.6 bars and at temperatures less than about 235 deg. C.

Assessment of Geothermal Potential in the Tbilisi Geothermal Reservoir

2022
<p>Taking into account the world-wide energy crisis, the search and rational use of cheap and</p><p>ecologically pollution-free renewable energy sources are extremely important. Among these sources the geothermal energy is of great potentialities.

Radon Transect Analysis in Geothermal Reservoirs

SPE California Regional Meeting, 1980
ABSTRACT Radon transect experiments have been conducted to study flow and emanation characteristics of geothermal reservoirs. Transect experiments have been carried out at three geothermal reservoirs: 1) The vapor-dominated field at The Geysers, California; 2) the liquid-dominated field at Wairakei, New Zealand; and 3) the liquid ...

Numerical Modeling of a Desaturating Geothermal Reservoir

Numerical Heat Transfer, Part B: Fundamentals, 1978
Abstract 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

Geothermal Reservoir Simulation

Proceedings, 2013
A three-dimensional (3D) numerical model was proposed for natural state simulation of the Las Tres Virgenes (LTV) geothermal system from emplacement and cooling of the heat source. The conceptual model is based on the volcanic history of the field. Chamber volumes were estimated from outcropping geology and eruptive volumes.

Isotope Geochemistry In Geothermal Reservoir Studies.

SPE California Regional Meeting, 1977
American Institute of Mining, Metallurgical, and Petroleum Engineers, Inc. Abstract Isotope geochemistry has contributed greatly to our scientific knowledge of geothermal systems. The near identity of deuterium isotopes of thermal waters and local rain waters has shown that geothermal systems are ...

Numerical Modeling Of The Wairakei Geothermal Reservoir

SPE California Regional Meeting, 1977
American 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 ...

Nonstatic Reservoirs: The Natural State of the Geothermal Reservoir

Journal of Petroleum Technology, 1983
Summary Above-hydrostatic-reservoir-pressure gradients are found in many geothermal fields before exploitation. In higher-temperature fields, steam and water also coexist in the upper levels. These factors indicate natural upflow in these reservoirs-i.e. the dynamic state of the fluid.
