This paper reports the first results of stress-oriented and aligned perforation of deviated wells at the Kuparuk River field, Alaska. Preferred perforation alignment and spacing are calculated for each well so the fractures from individual perforations link to produce a single zipper fracture plane along the deviated wellbore. Results of the first application of this technique are presented from the 26-well development of Drillsite 2K. The results from use of three different oriented-casing-gun systems and pertinent data from Drillsite 2K fracture stimulation treatments are discussed. Comparisons to drillsite where nonaligned perforating strategies were used show a significant reduction in perforation friction, enabling the placement of large, more productive fracture treatments. Application of this technique to deviated and vertical wells and its use at Kuparuk on developments after Drillsite 2K are discussed.
