The German Continental Deep Drilling Programme (German: Kontinentales Tiefbohrprogramm der Bundesrepublik Deutschland, lit. 'Continental deep-drilling program of the Federal Republic of Germany'), abbreviated as the KTB borehole, was a scientific drilling project carried out from 1987 to 1995 near Windischeschenbach, Bavaria.
The KTB superdeep borehole (German Continental Deep Drilling Programme, 1987–1995) at Windischeschenbach in northern Bavaria was drilled to a depth of 9,101 metres (29,859 ft), reaching temperatures of more than 260 °C (500 °F). Its ambitious measuring program used high-temperature logging tools that were upgraded specifically for KTB. [23]
ICDP supports international science teams with a proven need for continental-based drilling. The proposed projects help to answer societal challenges related to dynamics of planet Earth, contributing to major advances in understanding Earth's environment and life, sustainable geo- and energy resources, as well as safeguarding from natural disasters.
For many years, the world's longest borehole was the Kola Superdeep Borehole in Russia. From 2011 until August 2012 the record was held by the 12,345-metre (40,502 ft) long Sakhalin-I Odoptu OP-11 Well, offshore the Russian island Sakhalin. [11] The Chayvo Z-44 extended-reach well took the title of the world's longest borehole on 27 August 2012 ...

Drilling operations ceased in 2007. Located near the town of Parkfield, California, the project installed geophone sensors and GPS clocks in a borehole that cut directly through the fault. [3] This data, along with samples collected during drilling, helped shed new light on geochemical and mechanical properties around the fault zone.
