Conoco files for pads portion of project Western North Slope Service Pipeline Replacement project includes expansions of Kuparuk CPF2 pad and Colville River unit MIGI pad Kristen Nelson Petroleum News
ConocoPhillips Alaska is continuing the process of permitting for its Western North Slope Service Pipeline Replacement project, which includes pipelines and pad expansions. A public notice on the applications for pad expansions was posted Aug. 19 by the Alaska Division of Oil and Gas. Expansions would occur at the Central Processing Facility 2 pad in the Kuparuk River unit and the Miscible Injection/Gas Injection pad in the Colville River unit. The division said in the public notice that the pad expansions will accommodate new modules and equipment in support of the WNS Project.
In its Aug. 2 application ConocoPhillips Alaska said expansion of the MIGI pad would add 0.7 acre on the northeast side, while the CPF2 expansion would add to the south and east sides.
The company said project work is expected to begin Nov. 1 and be completed by June 30, 2024.
CPF2 at Kuparuk The CPF2 pad expansion will allow the company to install a new remote electrical and instrumentation module, and pump and pigging facilities for delivery of seawater and diesel to the Alpine Central Processing Facility. Existing infrastructure will be used during construction.
The CPF2 pad expansion will also accommodate a new diesel tank truck loading area and diesel storage tanks.
Some 13,000 cubic yards of clean gravel fill will be placed on 0.7 acres of wetlands and 0.3 acre of gravel pad sides on the south and east side.
ConocoPhillips said pipeline components of the project are being permitted separately with the State Pipeline Coordinator’s Section and include replacing the existing 12-inch Alpine utility pipeline with a new 20-inch pipeline to transport seawater from CPF2 to the existing MIGI pad on a new pipe rack. The project also includes installation of a new 4-inch products pipeline to transport diesel and other products from CPF2 to ACF on a spare slot on the existing Alpine sales oil pipe rack.
Horizontal directional drilling will be used at the Colville River for both pipelines and “will require constructing two new HDD transition pipeline pads north of the existing Alpine HDD location on the east and west sides of the Colville River,” ConocoPhillips said.
The CPF2 project could begin as early as Aug. 1, 2022, and will be completed by Dec. 31, 2023, “when all supporting infrastructure at the CPF2 pad expansion is installed,” the company said.
MIGI at Colville River unit Expansion of the MIGI pad at the Colville River unit will require some 8,000 cubic yards of clean gravel fill. The MIGI pad is north of CD4 in the Colville River pad.
“The existing MIGI pad is a wide area of the existing CD4 road, and the pad expansion is just north of CD4,” ConocoPhillips said.
The expansion will allow for a new remote electrical and instrumentation module “and a pigging module to contain pigging receivers and launchers” in support of the WNS Service Pipeline Replacement project.
The company said the expansion will add some 180 feet by 195 feet to the existing pad. Gravel placement will be over one winter season. Gravel sources being considered are the ASRC Mine Site, the Willow Mine site or a mine site in the Kuparuk River unit.
“The permitted WNS Resupply Ice Road will be used to support the project,” ConocoPhillips said, with other ice permitted through the North Slope Borough.
Pipelines In an Aug. 2 application to the State Pipeline Coordinator for a right-of-way lease for a new Western North Slope 4-inch product line (see story in Aug. 22 issue of Petroleum News), ConocoPhillips said work on that project is expected to begin this November and be completed by June 2024 with a target startup for the pipeline as early as December 2023.
The 4-inch products line will “import diesel and other products” for use in the Colville River unit, the Greater Mooses Tooth unit and “eventually” at the Bear Tooth unit “for powering equipment, supporting well work operations, and for freeze protection of wells.” The 4-inch line will be placed in a spare slot on the existing Alpine Sales Oil pipe rack.
An application for the 20-inch utility line had not yet been posted when this issue of Petroleum News went to press.
