The original 16-inch Kuparuk Pipeline (KPL), laid in 1981, carried processed crude oil to Pump Station (PS) 1. Later that same year, the Kuparuk Pipeline Extension (KPE) was constructed from Central Processing Facility 2 (CPF-2) to CPF-1, and comprised both 12-inch and 18-inch segments. In 1984, when the new 24-inch Kuparuk Pipeline was laid, the original Kuparuk Pipeline was converted to the Oliktok Pipeline, which now carries natural gas liquids from PS 1 (Skid-50) back to CPF-1. The KPE was also placed in service at this time and connected to the 24-inch KPL. In 2009, as part of a smart pigging project, the 12-inch segment of the KPE was replaced with 18-inch pipe, which made that portion of the pipeline piggable.
