The German Continental Deep Drilling Project (KTB) is currently drilling a scientific well in northeastern Bavaria at the intersection of the African and northern European tectonic plates. This well is scheduled to reach a depth of [approximately]10 km with the intent of studying the geochemical processes involved in the alteration of minerals under high temperature and pressure. The initial phase of this project focused on sinking a pilot hole to a depth of 4 km situated 200 m west of the deep well (Hauptbohrung). This pilot hole was fully cored (over 90 successful recovery) and extensively logged with both commercial and experimental logging systems. Cores, as well as cuttings and fluids, were analyzed in the [open quotes]field laboratory[close quotes] at the drill site established specifically for that purpose.
