Pipeline description

Point Thomson Export pipeline - extends about 22 miles from the Point Thomson Central Pad (CP), located approximately 60 miles east of Prudhoe Bay, to a point of connection with the existing Badami Sales Oil Pipeline at the Badami Central Facilities Pad (CFP). The PTEP lease was issued in 2012, with construction on the pipeline beginning just after. Pipeline construction was completed in 2013, with transportation of product through the line beginning in 2016.

Badami Sales Oil Pipeline - connects the Badami and Point Thomson fields to the Endicott Pipeline. The 12.75-inch pipeline begins at the Badami Central Production Facility and ends approximately 25 miles to the west at the tie-in with the Endicott Pipeline, where the pig receiver is located. The Right-of-Way Lease became effective December 15, 1997.

Endicott Pipeline - originates on Endicott's Main Production Island (MPI) located offshore in the Beaufort Sea, 15 miles east of Prudhoe Bay. This 16-inch diameter, 26-mile long pipeline is elevated along the Endicott Causeway, parallel to the Endicott Road, and ends at the Trans-Alaska Pipeline System's Pump Station 1 (PS1). As part of the North Slope Pipelines System, the Endicott Pipeline transports processed crude oil from Endicott, Badami, and Point Thomson fields to PS1. The Right-of-Way Lease became effective August 5, 1986 and was originally between the State of Alaska and BP Transportation Inc. and Amoco Endicott Pipeline Company. The lease is currently held by Harvest Alaska, LLC and expires on May 2, 2034.

NorthStar - moves crude from the Northstar oilfield (located six miles off the Beaufort Sea coast and 11 miles northwest of Prudhoe Bay) to Pump Staion 1 for the TransAlaska Pipeline. Oil was originally discovered in the NorthStar Unit by Shell in 1983 with exploration wells drilled from Seal Island. BP acquired most of the NorthStar Unit leases in 1995 and developed the field. On May 29, 2014, BP requested that DNR approve a transfer of its interests in the NorthStar pipelines to Harvest Alaska, LLC. Today, Harvest Alaska, LLC, operates the 10-inch oil pipeline and 10-inch gas pipeline that extend into the Beaufort Sea to the gravel island, sometimes referred to as NorthStar Island or Seal Island. The pipeline lease renewal review is in process.

Kuparuk Pipeline - 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.

Milne Point Pipeline - originates at Milne Point Central Facilities Pad, passes below Spine Road east of Central Processing Facility One (CPF-1) and terminates at the Kuparuk Pipeline connection near Module 68. The 14-inch diameter pipeline was designed to transport processed crude oil from Milne Point Unit to Kuparuk Pipeline. Milne Point Oil Pipeline was constructed from 1984 to 1985.

Alpine Oil Pipeline - one of three pipelines, each approximately 34 miles long, that connect the Colville River Unit (CRU) to infrastructure in the Kuparuk River Unit (KRU). The Alpine Oil Pipeline transports processed crude oil from the CRU Alpine Central Facility (ACF) to the KRU Central Processing Facility (CPF)-2. The Right-of-Way Lease became effective December 15, 1998 and was originally between the State of Alaska and Atlantic Richfield Company for crude oil transportation. The lease is held by ConocoPhillips Company and expires on December 14, 2048.

Sales Oil Pipeline (ENI) - moves crude from the ENI Oliktok production pad to the Kuparak oil pipeline

Lisburne - brings crude from the Lisburne field to Pump Station 1 on the TransAlaska Pipeline
