Project - Mackenzie Valley Natural Gas Pipeline Route Project

Taglu Development Plan Application Under the Canada Oil and Gas Operations Act

Taglu is the largest discovered onshore natural gas field in the Mackenzie Delta. It is one of three natural gas fields proposed for development as part of the Mackenzie Gas Project, to deliver sweet natural gas and natural gas liquids (NGLs) to market.

The Taglu field is located near the northern margin of the Mackenzie Delta, about 120 km north-northwest of Inuvik and about 70 km west of Tuktoyaktuk. The field is estimated to contain 81 Gm³ (2.8 Tcf) of recoverable raw natural gas and NGLs.

In October 2004, Imperial Oil Resources Limited, as the registered interest holder of Significant Discovery Licence (SDL) 063 for the Taglu field, applied to the National Energy Board (NEB) for approval to develop the natural gas and NGLs at Taglu. The application was submitted under the Canada Oil and Gas Operations Act (COGOA).

The application describes the general approach to developing the natural gas resource from the Taglu reservoir. Included in the development plan is a summary of the environmental and socio-economic impact assessments and public consultation programs completed for the proposed Taglu development.
