The Clearwater heavy oil play in Alberta continues to emerge as one of the most economic oil developments in North America. Tamarack Valley Energy has positioned itself at the center of this growth, describing itself as the largest public producer in the Clearwater formation.
Recent company disclosures and drilling data show how Clearwater has become the core asset driving Tamarack’s production growth, while pad drilling and waterflood expansion are shaping the next phase of development.
Clearwater Now Drives Tamarack’s Production
Tamarack Valley Energy has completed its transition toward a development model focused primarily on Clearwater and Charlie Lake heavy oil assets, with Clearwater representing the majority of the company’s activity.
In the fourth quarter, Tamarack reported Clearwater production of approximately 50,000 barrels of oil equivalent per day, representing a 16% increase year-over-year. Clearwater production now accounts for most of the company’s total output of roughly 68,000 BOE per day.
Management continues to highlight the scale of the opportunity. Tamarack controls more than 850 net sections of land across the Clearwater fairway, with an inventory of over 2,100 drilling locations and more than 25 years of development potential.
Across this acreage position, Tamarack estimates the Clearwater formation contains approximately 12 billion barrels of oil in place.
Drilling Activity Expands in 2025
Tamarack’s development program accelerated significantly in 2025. The company drilled 94.3 net horizontal wells targeting primary heavy oil production, while simultaneously expanding the infrastructure needed to support secondary recovery.
Additional drilling included:
- 25 water injection wells
- 2 source water wells
- 16 producing wells converted into injectors
These wells support the continued build-out of Tamarack’s waterflood program, which management believes will significantly increase oil recovery across the play.
Pad Drilling Dominates Clearwater Development
An analysis of Tamarack Clearwater drilling activity reveals how pad development has become the dominant strategy for the play.
Using surface location clustering within 60 meters to identify drilling pads, the dataset contains:
- 140 wells
- 29 drilling pads
- Average pad size of approximately 5 wells
Several large development pads were identified, including multi-well pads with 10 to 17 wells drilled from a single location.
Pad drilling allows operators to reduce costs and improve efficiency by drilling multiple horizontal wells from one surface location. This approach minimizes surface disturbance while allowing rigs to “walk” between wells.
Most drilling activity is concentrated in the Marten Hills and Marten areas, which account for the majority of wells in the dataset.
Rig and Contractor Activity
The pad analysis also highlights the mix of drilling contractors active in Tamarack’s Clearwater program.
Several rigs appear repeatedly across multi-well pads, suggesting extended drilling campaigns where rigs move between wells without leaving the pad.
Key contractors identified in the data include:
- Precision Drilling
- Horizon Drilling
- Komat Drilling
- Savanna Drilling
Precision and Horizon rigs appear most frequently in the Marten Hills development area, while Savanna rigs are associated with smaller programs in other fields.
This pattern reflects the large-scale, continuous drilling campaigns required to develop multi-well pads.
Waterflood Emerges as the Key Value Driver
While primary heavy oil production remains the initial development phase, Tamarack increasingly emphasizes waterflooding as the long-term value driver for the Clearwater play.
Currently:
- 10–15% of Tamarack’s acreage is under waterflood
- 24% of production is supported by flood projects
By the end of 2026, the company expects waterflood to support approximately 35% of total production.
Water injection volumes are also rising rapidly. Tamarack exited 2025 injecting roughly 40,000 barrels of water per day, with a target of 60,000 barrels per day by 2026.
The impact is already visible, with waterflood projects contributing approximately 5,000 barrels per day of incremental production.
Significant Recovery Potential Remains
Despite the rapid growth in production, Clearwater recovery factors remain relatively low compared to other heavy oil developments.
Current reserves imply recovery of only about 3% of the oil in place.
However, Tamarack notes that analog heavy oil reservoirs using waterflood techniques can achieve recovery factors between 25% and 40%.
If similar results are achieved in Clearwater, the formation could deliver decades of additional production and reserve growth.
Clearwater Economics Remain Strong
One of the most compelling aspects of the Clearwater play is its cost structure.
Tamarack reports:
- Finding and development costs of approximately $7 per BOE
- Recycle ratios near 6x
These economics allow Tamarack to maintain a corporate breakeven below $40 WTI, positioning the company to generate strong free cash flow even in moderate oil price environments.
New Areas Could Expand the Play
Tamarack is also exploring potential expansion areas beyond its current core development zones.
One of the most notable is Pelican, where the company plans to drill two evaluation wells in 2026:
- One targeting Clearwater
- One targeting Wabiskaw
If these wells are successful, Pelican could evolve into a 5,000 to 10,000 barrel per day development area.
Clearwater Still in the Early Stages
Despite the rapid pace of drilling and production growth, Tamarack management repeatedly emphasizes that Clearwater development remains in its early stages.
The current strategy focuses on:
- Expanding primary horizontal drilling
- Building waterflood infrastructure
- Increasing recovery factors over time
With a large land position, strong well economics, and improving recovery through waterflooding, Tamarack believes the Clearwater play will remain a major driver of production growth and shareholder returns for decades to come.
