History

The Deep Panuke Offshore Gas Development Project is operated by Ovintiv Canada ULC (formerly Encana) . Production began in August 2013, and was permanently shut-in in May 2018. The Deep Panuke Offshore Gas Development Project operated on a seasonal basis from 2015-2018, with production only during the colder winter months, when natural gas prices were higher. The Deep Panuke Offshore Gas Development Plan estimated the most likely volume of natural gas that would be produced, over the expected production life of 13 years, to be 17.8 billion cubic meters or 632 billion cubic feet.

The Field

The Deep Panuke Offshore Gas Development Project gas field is located on the Scotian Shelf, approximately 250 kilometres southeast of Halifax. Natural gas was produced from the Abenaki Formation carbonate reservoir by four production wells.

Operations

The gas produced and processed offshore was transported via subsea pipeline to shore, and ultimately, to markets in Canada and the United States. The Deep Panuke Offshore Gas Development Project utilized a jack-up type offshore production platform, called the Production Field Centre, which was tied back to the four subsea production wells by subsea flow lines. The Production Field Centre was designed for a peak gas rate of 8.5 million cubic metres per day, or 300 million standard cubic feet per day.

The raw gas produced at The Deep Panuke Offshore Gas Development Project contained approximately 0.18% hydrogen sulphide; therefore, gas sweetening equipment was installed on the Production Field Centre. An amine unit was used to remove hydrogen sulphide along with carbon dioxide, both of which are considered acid gas. After removal, the acid gas was injected into a purpose drilled disposal well.

Decommissioning and Abandonment

Production from the four Deep Panuke Offshore Gas Development Project wells was permanently shut-in in May 2018. Planning for the permanent plugging and abandonment of the wells is underway. The plug and abandonment program will involve the use of a jack-up drilling rig to set a series of cement and mechanical plugs within the wellbore to permanently seal the wells in accordance with the regulations. This is to prevent hydrocarbons from migrating within or out of the well.

Project Information

We publish reports and data on oil and gas activities. View the status of a project and reports related to production, environmental effects monitoring, and industrial benefits, if available, below. You can also view requests made by operators for project deviations, and decisions made by our Chief Safety Officer or Chief Conservation Officer to ensure that regulatory requirements are upheld.

Application StatusOperators working in the Canada-Nova Scotia offshore area must submit an application and an authorization must be granted before this work can begin. View current applications and approval statuses here.

* Operations Authorization – Production (OA-P) grants approval for a proponent to carry out any activity in the Canada-Nova Scotia offshore area related to oil and gas production.

* Approval to Alter the Condition of a Well (ACW) is required to re-enter, workover, complete, recomplete, suspend or abandon a well or part of it. The application for an ACW is reviewed in conjunction with the operator’s application for an Operations Authorization – Drilling (OA-D) or Operations Authorization – Production (OA-P), as applicable. 

*  The current Operations Authorization - Production will expire on September 30, 2020.
