Our Approach - Repurpose Before Abandonment

CedarStone Energy works to identify the remaining value in mature oil and gas infrastructure before final abandonment and reclamation decisions are made.

  • A wellbore may no longer be economic for hydrocarbon production, but it may still provide access to geothermal heat.
  • A pipeline may no longer serve its original production purpose, but it may support produced water transfer lines.
  • Produced water may currently be treated as a waste stream, but with the right treatment pathway, it can become a renewable resource.
  • A mature lease site may be viewed as a closure obligation, but it can also become the foundation for heat, power, water treatment or greenhouse infrastructure.

Our model bridges the gap between liability management and regenerative asset development.

Our Solutions

Repurpose Oil and Gas Well into Geothermal Well for Green Hydrogen Production

CedarStone Energy investigates the repurposing of suitable high-temperature oil and gas wells, including wells with bottomhole temperatures over 100°C, into geothermal-assisted energy assets. These wells may support green hydrogen production by using subsurface heat to pre-heat water, reduce the electrical load required for electrolysis, and integrate existing wellbore infrastructure into a lower-impact hydrogen production model.

By using existing wells, surface locations, access roads, and field infrastructure, this approach can reduce new land disturbance, lower capital intensity, and create a new productive use for assets that may otherwise move toward suspension, abandonment, or reclamation.

Potential Benefits
  • Repurposes existing wellbores and surface infrastructure
  • Reduces the need for new drilling and new surface disturbance
  • Supports lower-carbon hydrogen production
  • Reduces electrical load on the grid
  • Creates new value from mature or inactive energy assets
  • Supports regional clean-energy development

Not every well needs to be high-temperature to create value.

CedarStone Energy investigates the use of low-temperature oil and gas wells, including wells under 100°C, as geothermal heat sources for greenhouse heating, heat-pump integration, and seasonal heating and cooling systems. This opportunity is especially relevant for northern, rural, Indigenous, and remote communities where food costs, transportation logistics, diesel reliance, and energy security are ongoing challenges. By converting low-temperature wellbores into thermal assets, CedarStone Energy can help support year-round greenhouse production, food security, local employment, and reduced dependence on long-distance food transportation.

Potential Benefits:
- Repurposes low-temperature wells into productive thermal assets
- Supports year-round greenhouse operations
- Reduces heating costs for remote and northern communities
- Strengthens local food security
- Creates local employment and training opportunities
- Reduces dependence on imported food and high-emission logistics

Produced water is one of the most significant operational challenges in the oil and gas sector. It is often managed as a waste stream, disposal burden, or ongoing operating cost. Operators may pay for trucking, disposal, injection, storage, treatment, and compliance while also managing emissions and field logistics associated with water movement.

CedarStone Energy is exploring natural and lower-impact treatment pathways that could transform produced water from a waste product into a valuable resource. Our goal is to reduce disposal volumes, trucking requirements, injection dependency, operating costs, and transportation-related emissions while creating beneficial reuse pathways for water where technically feasible and regulatorily appropriate.

Potential Benefits:
- Reduces produced-water trucking and disposal costs
- Lowers transportation-related CO₂ emissions
- Supports water stewardship and circular resource use
- Reduces pressure on disposal infrastructure
- Creates new beneficial-use opportunities for fracking and agricultural sectors
- Turns a costly waste stream into a recoverable asset

CedarStone Energy also sees opportunity in inactive, underutilized, or soon-to-be inactive pipeline infrastructure. Where pipeline integrity, regulatory approvals, fluid compatibility, land agreements, and operating conditions allow, certain pipelines may be repurposed into produced-water intake or transfer lines. This could reduce trucking, lower emissions, improve field logistics, and extend the useful life of existing infrastructure.

Potential Benefits:
- Repurposes inactive or underutilized pipelines
- Reduces truck traffic and road impacts
- Lowers produced-water transportation costs
- Reduces transportation emissions
- Supports closed-loop water movement
- Extends the useful life of existing field infrastructure
