    The geothermal water is supplied by five production wells and injected by six injection wells. There is a program to add three new production wells. [1] The depth of wells is 4,000–8,000 feet (1,200–2,400 m). [2] The technology was supplied by Ormat Technologies. [1] [2] The well drilling contractors were ThermaSource and Ensign. The piping ...

    NGDS was initially funded by the United States Department of Energy Geothermal Technologies Program (awards DE-EE0001120 and DE-EE002850), as part of the American Recovery and Reinvestment Act of 2009. The National Geothermal Data System makes use of the large collection of hard copy documents stored in state geological survey archives.

    The geothermal production well reached a depth of 5,275 m (17,306 ft) and the fluid injection well 2,393 m (7,851 ft). [ 3 ] [ 1 ] Between August 2020 and July 2021, the wells underwent a series of injection tests to analyse the hydrology within the fractured geothermal reservoir.

  5. Ground source heat pump - Wikipedia

    en.wikipedia.org/wiki/Ground_source_heat_pump

    A standing column well system is a specialized type of open-loop system where water is drawn from the bottom of a deep rock well, passed through a heat pump, and returned to the top of the well. [18] A growing number of jurisdictions have outlawed open-loop systems that drain to the surface because these may drain aquifers or contaminate wells ...

  6. Closed-loop geothermal - Wikipedia

    en.wikipedia.org/wiki/Closed-loop_geothermal

    Closed-loop geothermal systems (also known as “advanced geothermal systems” or “AGS”) are a type of engineered geothermal energy system containing subsurface working fluid that is heated in a hot rock reservoir without direct contact with rock pores and fractures.: [1] [2] [3] Instead, the subsurface working fluid stays inside a closed loop of deeply buried pipes that conduct Earth’s ...

    As of 2007 plant construction and well drilling cost about €2–5 million per MW of electrical capacity, while the break-even price was 0.04–0.10 € per kW·h. [10] Enhanced geothermal systems tend to be on the high side of these ranges, with capital costs above $4 million per MW and break-even above $0.054 per kW·h.

    NM4 was the first well in New Zealand to encounter a pluton, at a depth of almost 2400m. Mighty River Power undertook further drilling in 2008-09, with wells NM5, NM6, and NM7 drilled to depths of 2997m, 3398m, 2963m respectively. [5] Resource consents for further development were granted in May 2010. [6]

    The study of Massachusetts Institute of Technology "The Future of Geothermal Energy – Impact of Enhanced Geothermal Systems (EGS) on the United States in the 21st Century" (2006) points out the essential importance of developing an economical deep geothermal boring technology. With old boring technologies, bore price rises exponentially with ...
