The plan was to reach a maximum depth of 5 km (3.11 mi) before the end of 2016, making it by far the deepest borehole in Iceland. [12] Scientists were hoping to reach a temperature of 500 °C (930 °F), [ 13 ] [ 14 ] which would be the hottest blast of any hole in the world, breaking the former record of the IDDP-1 Krafla borehole.
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 highest concentrations are located in the Mayacamas Mountains and Imperial Valley of California, as well as in Western Nevada. The first geothermal area to be exploited for commercial electricity generation was The Geysers , a complex of 22 geothermal power stations located in Sonoma and Lake counties of California , which was commissioned ...
The Sonoma Calpine 3 power plant is one of 22 power plants at The Geysers in the United States. This is a list of operational geothermal power stations with a current installed capacity of at least 10 MW. The Geysers in California, United States is the largest geothermal power station in the world with a nameplate capacity of 1,590 MW and an annual generation of 6,516 GWh in 2018. Geothermal ...
Most drilled geothermal exploration wells, up to the production well, are still considered to be within the exploration phase. Most consultants and engineers consider exploration to continue until one production well is completed successfully. [4] Generally, the first wildcat well has a success rate of 25%. Following more analysis and ...
The project was abandoned by the Department of Energy, but Southampton City Council took the decision to create the UK's first geothermal power scheme. This was undertaken as part of a plan to become a "self sustaining city" in energy generation, promoted by City Council officer Mike Smith and council leader Alan Whitehead. [1] [2] [3]
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.
