In March 1999, Total Austral SA (operator), Deminex, and Pan American Energy drilled an extended-reach, HD (horizontal-displacement) record of 10,585 m (34,728 ft) from an onshore location in Tierra del Fuego, Argentina. By combining innovative technologies, learning experience, and a slimhole well configuration, these companies saved 3 Mio USD, or 20 % of the originally planned costs for this 11,184 m (36,693 ft) long well. This first of a two-part series describes the innovative technologies and well-design configuration used on the Cullen Norte Number 1 well. These innovations include the first use of an onshore horizontal lay-down-pickup machine and the refitting of small-diameter drill pipe and tubulars with high-torque, wedge-thread pipe connections. The conclusion describes other downhole and surface technologies, including PDC (polycrystalline diamond-compact) bit selection, subsurface data gathering, cuttings-weighing equipment, and pertinent operational details that helped achieve this world record.
