As capital budgets tighten and producers look for creative ways to squeeze more life and profit from mature wells, a quiet but impactful optimization trend is emerging in Western Canada’s Cardium formation in particular – the conversion of pumpjack wells to plunger lift systems.
The reason for this trend is becoming quite clear, as a growing number of producers are discovering that converting their pumpjacks to plunger lifts can deliver big returns for a relatively small investment.
In an industry where efficiency often trumps expansion, a quiet optimization trend is gaining momentum – converting aging pumpjack wells to plunger lift systems.
The approach is delivering notable results in Western Canada’s Cardium formation, where high gas-to-oil ratios (GOR) make many wells ideal candidates. In several recent cases, these conversions have yielded 20% production gains, reduced workovers, and sharply lower operating costs – all while requiring a modest capital outlay.
“What we’re seeing is a way for producers to unlock stranded performance potential in wells they thought were in permanent decline.” says Devin Swanson, President at Central Optimization.
Cardium wells have long been known for their frothy, gas-laden flow – challenging conditions for pumpjacks as GOR increases over time. Traditional pumps struggle with the inconsistent flow, leading to frequent mechanical failures, rising chemical costs, and diminishing returns.
But that same gas can be put to work. By converting to plunger lift, producers can use the well’s natural energy to lift liquids more efficiently.
For one Alberta well recently converted by Central Optimization, the economics were undeniable:
All three Cardium wells converted in this pilot program showed similar results – a rare level of consistency in field optimization work. Read the Full Case Study
And this is by no means an anomaly. A previous 2017 well study that Central’s founders were also involved in showed similarly impressive results. The project, involving 23 wells and also in the Cardium, resulted in:
But not every well is a good fit for plunger lift. Candidate selection is critical – and that’s where expertise and data modeling play a critical role.
That’s why Central Optimization, one of Alberta’s most experienced well optimization firms, employs predictive analysis tools to model success before a conversion is approved. This method allows producers to de-risk the investment by verifying that a well has the right pressure and flow dynamics to support a plunger system.
“We can tell with a high degree of certainty whether a plunger lift will work before anyone spends a dollar,” says Devin. “That’s how we ensure that these projects deliver measurable value, not by guesswork.”
This approach is unique. Central is one of a select few in Western Canada that have developed and refined these predictive models.
The economic case is hard to ignore. A typical pump-to-plunger conversion costs around $55,000 per well, with payback often under seven months. However, if the conversion is timed with when the pump or rods fail, that net cost per well can drop down to the $17,000 range.
In addition, equipment wear is dramatically reduced, chemical use declines, and fewer workovers mean lower emissions and maintenance costs.
For producers managing mature wells – especially those in gas-rich oil zones – it’s a practical path to lowering lift costs and extending well life without major reinvestment.
With industry pressure to boost efficiency and sustainability, small optimization steps can yield big returns. Pumpjack-to-plunger conversions represent just one of those under-the-radar opportunities – a technical tweak that’s proving its worth across the Cardium and beyond.
As Devin reminds us, “The opportunity is right there in front of us. It’s just about using data, experience, and a little creativity to capture it.”
