- Destination: Alberta System Gas Pipeline, Alberta
- Ownership: Imperial Oil, ConocoPhillips, and Shell
- Website: http://www.mackenziegasproject.com/
- Length: 1,220 kilometre (758 mile)
- Capacity: 34 million cubic metres per day
- Status: Planned
- The pipeline project would be anchored by three onshore natural gas fields known as Taglu, Parsons Lake and Niglintgak, operated by Imperial Oil, ConocoPhillips, and Shell Canada, respectively.
- Imperial Oil has also applied for approval to construct a 176 kilometre (109 mile) gas gathering system to collect the gas from the three fields and deliver it to a processing facility near Inuvik. At the processing facility, natural gas liquids would be separated out.
- The natural gas would enter the proposed 1,220 kilometre (758 mile) pipeline which connects to the Alberta System Gas Pipeline
- The liquids would enter a smaller, parallel pipeline of approximately 475 kilometres (295 miles) that would connect to the Enbridge Pipelines (NW) Inc. pipeline at Norman Wells.
- The 762 millimetre (30 inch) natural gas transmission pipeline is planned to transport 34 million cubic metres (1.2 billion cubic feet) per day. The capital cost of the Mackenzie Gas Project is estimated at over $7 billion.
