Encana Corporation – Abandonment of Deep Panuke Offshore Gas Development

What’s New

Project Information

Encana Corporation (Encana) applied to the National Energy Board (NEB) on June 19, 2018 to abandon the Deep Panuke pipeline and associated onshore facilities. In its application, Encana says that it permanently ceased production from Deep Panuke on May 7, 2018 after reaching a stage of declining production.

The Deep Panuke gas field is located offshore about 250 km southeast of Halifax, Nova Scotia, approximately 47 km west of Sable Island in approximately 44 m of water. An offshore production platform produces and processes natural gas. The gas is transported to shore via a 175 km-long export pipeline to an interconnection with the Maritimes & Northeast Pipeline (M&NP) facilities in Goldboro, Nova Scotia. Please visit Encana’s Deep Panuke website for additional details.

The export pipeline is regulated by the NEB and partially by the Canada – Nova Scotia Offshore Petroleum Board. About three kilometres of the export pipeline is onshore, while the rest of the pipeline is offshore. Encana proposes to pig and flush the pipeline, fill it with seawater, leave the offshore end open, and abandon the pipe in place. The abandoned offshore portion of the pipeline will be marked as abandoned on navigation charts. The company has also applied to abandon the NEB-regulated onshore facilities consisting of a beach valve station, gas export pipeline terminus site, and access roads.

If the NEB approves this application, Encana plans to carry out the decommissioning and abandonment activities from 2018 – 2021.

  6. The appropriateness of the land requirements for the Abandonment.
  7. Potential impacts of the Abandonment on Indigenous interests.
  8. Potential impacts of the Abandonment on both affected landowners and land use, and offshore use and users; including: fishers, navigation, offshore activities, and any infrastructure crossings of the NEB-regulated facilities.
  9. Contingency planning for product release, as a result of accidents or malfunctions, during physical work associated with the Abandonment.
  10. Safety and security during activities conducted in relation to the Abandonment.
