Three extended-departure horizontal wells have been drilled and completed in the Prudhoe Bay Unit, AK, by Standard Alaska Production Co. Horizontal slotted-liner completions of 1,575, 1,637, and 1,163 ft (480, 499 and 354 m) were achieved at an average vertical depth of 9,000 ft (2743 m). Over the three-well program, improvements in technology and operating procedures have resulted in a 40% reduction in cost per foot. When compared to conventional completions, production data from the horizontal wells indicated rate benefits up to 300% and a potential increase in ultimate recovery. This paper discusses the development of the techniques used to drill horizontal wells at Prudhoe Bay and reviews the horizontal drilling operations for each well.
