[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).

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 ...
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]
Simply put, geothermal energy is heat contained deep within Earth. According to the U.S. Energy Information Administration, that heat is a result of radioactive particles like uranium, thorium ...
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".
The Bertha Rogers Borehole is a former natural gas well in Burns Flat, Dill City, Oklahoma, US.Today plugged and abandoned, it was originally drilled by the Lone Star Producing Company as its oil-exploratory hole number 1–27 between October 25, 1972 and April 13, 1974, reaching a then world record terminal depth of 31,441 feet (5.9547 mi; 9,583 m).
The Lone Star Bertha Rogers well in Beckham County, Oklahoma held the record as the world's deepest producing well in 1974-1979. It has subsequently been surpassed by several other deep wells, see deepest artificial point. It was drilled to a depth of 31,441 feet (9,583 m). [1]
Sonar mapping of the Challenger Deep by the DSSV Pressure Drop employing a Kongsberg SIMRAD EM124 multibeam echosounder system (26 April–4 May 2019). Challenger Deep (CD) is the deepest known point in the Earth's seabed hydrosphere, a slot-shaped valley in the floor of Mariana Trench, with depths exceeding 10,900 meters. [1]
