SnapshotChristina Lake includes a central processing facility, as well as field facilities.

In the third quarter of 2025, the Narrows Lake tie-back to the Christina Lake central processing facilities, including the construction of a 17-kilometre pipeline to connect the assets, was completed and is now ramping up production.

On November 13, 2025, Cenovus Energy Inc. (Cenovus) acquired MEG Energy Corp. (MEG), which has a 100% ownership of Christina Lake Regional Project (CLRP), operational since 2008. Now “Greater Christina Lake” includes Cenovus's Christina Lake and Christina Lake North (formerly MEG’s Christina Lake).

Christina Lake North expansion
• Adding two new steam generators and re-rating existing steam generators.
• Debottlenecking water and oil handling capacity.
• ~$400 million growth capital investment in 2026.
• Adding ~40 Mbbls/d of production to Christina Lake North by end of 2028.

Owners

Cenovus Energy Inc. 100 % Indirect
Cenovus Energy Inc. holds a 100% working interest in the Christina Lake asset.

Prior to its acquisition, MEG Energy Corp. held a 100% interest in the mineral leases associated with the Christina Lake North project, which is located adjacent to the core Christina Lake property. Effective November 13, 2025, MEG Energy Corp. became a wholly owned subsidiary of Cenovus Energy Inc. As a result of this transaction, Cenovus Energy Inc. now holds a 100% interest in the expanded Christina Lake project, including the former Christina Lake North area.

Cenovus has a 100 percent working interest in Narrows Lake, which is located adjacent to Christina Lake and has a reservoir depth of up to 400 metres. The expansion of the Christina Lake development area to include Narrows Lake will provide future sustaining pad locations for feedstock into the Christina Lake plant.

Summary:

Christina Lake produces from the McMurray formation, with a reservoir depth of up to 430 metres.

The McMurray Formation is a succession of sands and shale deposited in a fluvial estuarine environment that developed in a major valley that was cut into Devonian-aged limestone. Sands were deposited in tide-influenced channels and the McMurray Formation is variably saturated with water, bitumen and natural gas. Bitumen from the McMurray Formation has an average API gravity of approximately 8 degrees.

The unconsolidated sands of the McMurray Formation at the Christina Lake Project are suitable for in situ recovery. The reservoir is situated at an average depth of 360 metres. The reservoir ranges in thickness from 9 to 56 metres with an average approximate thickness of 19 metres. Bitumen saturation is between 60% and 85%. Reservoir sands have average porosity of 33%. Absolute permeability of the sand is 3,000 to 5,000 millidarcies. Initial reservoir pressure is 2,100 kPa and in situ reservoir temperature is 12° C. Bitumen viscosity at reservoir temperature is typically greater than 1,000,000 centipoise.
