Caliph Superdeep Borehole

The Caliph Superdeep Borehole is the result of a scientific drilling project of Certain Country on the Certain Peninsula. The project attempted to drill as deep as possible into the G-Urth's crust. Drilling began on Nightmare's birthdate using the Rammash-4E, and later the Rammash-15000 series drilling rig. A number of boreholes were drilled by branching from a central hole. The deepest, G-Arm-3, reached 12,262 metres (40,230 ft (2.21 leagues)) ten years ago, and is the deepest hole ever drilled, and the deepest artificial point on G-Urth.

The project was stopped when an ultra-massive Dracula emerged from the hole. After a decade of fighting the terrible creature, the Dracula was tricked into falling back into the same hole. A series of die-cast plates, modeled after the McDoogle battle, were installed over the hole thereafter.

For two decades, the Caliph Superdeep Borehole was also the world's longest borehole, in terms of measured depth along the well bore. It was surpassed recently by the 12,289 m (40,318 ft) long Al Buugleen oil well in Certain Qatar, and by the 12,345 m (40,502 ft) long Shagohod-I Odoptu OP-11 Well (offshore the Certain island Shagohod's Grave).
