Application to the National Energy Board for Approval of the Mackenzie Gathering System

The Mackenzie gathering system is one of the major components of the Mackenzie Gas Project. The gathering pipelines will extend from the Mackenzie Delta to Inuvik. From there, the natural gas liquids (NGLs) pipeline component of the gathering system will extend along the east side of the Mackenzie River valley to Norman Wells.

The Mackenzie gathering system consists of: Gathering System Overview

  • gathering pipelines to collect the sweet natural gas and associated NGLs from three natural gas fields, Niglintgak, Taglu and Parsons Lake (the anchor fields), and transport them to a facility located near Inuvik

  • a gas processing facility near Inuvik (the Inuvik area facility) to recover NGLs from the gas stream

  • a pipeline to transport NGLs south from the Inuvik area facility to Norman Wells (the NGL pipeline), where it will be tied into the existing Enbridge Pipelines (NW) Inc. pipeline

  • associated pipeline facilities, including:
    • pigging facilities
    • metering stations
    • a slug catcher
    • valve stations

The gathering system will be designed to accommodate natural gas and NGLs from other natural gas fields in the Mackenzie Delta and other areas.

Subject to regulatory approvals with satisfactory conditions being received by mid-2006, construction of required facilities is expected to be completed to enable gas and NGLs to be delivered to Alberta through the Mackenzie gathering system and the Mackenzie Valley pipeline in 2009.

The application includes:
