Pagosa hot springs are the world's deepest geothermal hot spring. [13] [14] In 2020 the depth was measured by a collaborative team from the Center for Mineral Resources Science (CMRS) and the Colorado School of Mines and the U.S. Geological Survey. The measuring device went to a depth of 1002 feet, but the "tape measure" had reached its full ...
[1] [28] It was also the longest borehole in the world from 1979 to 2008. Its record length was surpassed in May 2008 by the curved extended reach drilling bore of well BD-04A in the Al Shaheen Oil Field in Qatar, which attained a total length of 12,289 metres (40,318 ft) but depth of just 1,387 metres (4,551 ft).

Upper estimates of geothermal resources assume wells as deep as 10 km (6.2 mi). Drilling near this depth is now possible in the petroleum industry, although it is an expensive process. The deepest research well in the world, the Kola Superdeep Borehole (KSDB-3), is 12.261 km (7.619 mi) deep. [21]
All the deep boreholes are now available to hire for a range of down hole testing. There are three deep boreholes (2,350 m (7,710 ft), 2,180 m (7,150 ft), 2,800 m (9,200 ft)), four uncased 300 m (980 ft) holes and one 150 m (490 ft) hole inclined at 30 degrees, as well as micro seismic testing and a wind turbine test environment on this 20 ...
A geothermal well was used to heat greenhouses in Boise in 1926, and geysers were used to heat greenhouses in Iceland and Tuscany at about the same time. [9] Charles Lieb developed the first downhole heat exchanger in 1930 to heat his house. Geyser steam and water began heating homes in Iceland in 1943. Global geothermal electric capacity.
The Iceland Deep Drilling Project (IDDP) is a geothermal project established in 2000 by a consortium of the National Energy Authority of Iceland (Orkustofnun/OS) and four of Iceland's leading energy companies: Hitaveita Suðurnesja (HS), Landsvirkjun, Orkuveita Reykjavíkur and Mannvit Engineering. The consortium is referred to as "Deep Vision".

Although often confused with the relatively limited hydrothermal resource already commercialized to a large extent, HDR geothermal energy is very different. [3] Whereas hydrothermal energy production can exploit hot fluids already in place in Earth's crust, an HDR system (consisting of the pressurized HDR reservoir, the boreholes drilled from the surface, and the surface injection pumps and ...
