  • Dynamic simulation and 2D multiple scales and multiple sources within basin geothermal field

    In order to accurately describe the geothermal field within a basin, it is necessary to divide it into the normal geothermal field and additional geothermal field. For the accuracy by describing of the additional geothermal field, grids need to be increased. Traditional unequal interval difference method can be used to solve this problem, which has to increase grids within the unnecessary area, ...

  • A BME solution of the stochastic three-dimensional Laplace equation representing a geothermal field subject to site-specific information

    This work develops a model of the geothermal field in the Nea Kessani region (Greece) by means of the Bayesian maximum entropy (BME) method, which describes the temperature variations across space in the underground geological formations. The geothermal field is formed by a thermal reservoir consisting of arcosic sandstones. The temperature distribution vs depth was first investigated by the ...

  • Boron pollution due to geothermal wastewater discharge into the Buyuk Menderes river, Turkey

    Kizildere, which is the only commercial geothermal power plant in Turkey and located in Buyuk Menderes Graben in south-west Turkey, discharges annually 6 million tonnes of wastewater into the Buyuk Menderes river, creating environmental pollution. Currently, the wastewater, which includes up to 24 mg/l boron, is discharged into the river at a rate of 750–1500 tonnes per hour. The temperature of ...

  • Evaluation of utilisation opportunities of geothermal energy in the Kavala region, Greece, using exergy analysis

    Greece has a lot of geothermal energy fields. Due to legal inefficiencies, the exploitation of this renewable energy source remains at very low levels. In this work, the operation of a cogeneration (hot water and electricity) geothermal plant that could be built in Eratino, Greece, is analysed. The research on the development of a low enthalpy geothermal field is investigated as a very essential ...

  • Projects Thermoelectric Generators in a Geothermal Field - Case Study

    This is an R&D project which will build and test a new field-scale thermoelectric generator (TEG) at our Bottle Rock Power geothermal facility near Cobb, California. TEGs produce electrical energy when a strong enough temperature difference exists across the generator (a phenomenon known as the Seebeck effect). This will be the first ...

  • Case Study - Aluto Langano Power Plant Rehabilitation

    Aluto Langano, Ethiopia – 2007 The Aluto Langano Geothermal Pilot Plant (ALGPP) is located on the Aluto volcanic complex of the Ethiopian Rift valley, close to the eastern escarpment between Lake Langano and Lake Ziway, some 200 km southeast of Addis Ababa. The Aluto volcanic complex is a young acidic system consisting of domes, lava, and pyroclastic interbeds. The geothermal field was ...

  • Re-energizing California

    Multiparameter flowmeter improves process, saves money at western energy company Sierra Instruments is hard at work in the geothermal steam fields of rhc Wcsr where rugged reliability matters. In energy-strapped California, one emerging technology is using the natural geothermal reservoirs in certain areas as a source of steam that is then used to generate electricity. ...

  • Projects Davenport Newberry Holdings, LLC. - Case Study

    AltaRock Energy, Inc. actively manages over 40,000 acres of geothermal leases on the western flank of Newberry Volcano in central Oregon. The leases, held by Davenport Newberry Holdings, LLC. (DNH) and administered by the US Bureau of Land Management, represents a unique opportunity to test and develop Enhanced Geothermal System (EGS) technologies in the field. In partnership with the US ...

  • Artificial geothermal energy potential of steam-flooded heavy oil reservoirs

    This paper explores the concept of harnessing geothermal energy from heavy oil fields that have undergone steam flooding and so accumulated substantial heat from steam injection. Once the steam flooding process reaches economic cut-off resulting from high water cut and/or high steam-to-oil ratio, the reservoir would be abandoned, leaving behind stored energy in the form of heat. From this point, ...

  • As Global Demand for Electricity Grows, Geothermal Energy Heats Up

    January 9, 2017 — At 2:46 p.m. local time on Friday, March 11, 2011, Japan was rocked by the largest earthquake ever to strike its shores. The 9.1 magnitude quake triggered a devastating tsunami that killed more than 15,000 people. It also took out the back-up emergency generators that cooled the reactors at the Fukushima Daiichi nuclear power plant complex, causing a series of ...
