Why PetroLegacy Energy Now Runs Entirely on ComboCurve

March 27, 2025

Jason Churchill shares PetroLegacy Energy's journey of fully transitioning to ComboCurve for reserves and A&D workflows. After years of using legacy software alongside ComboCurve, PLE now relies solely on ComboCurve for all evaluations, forecasting, and reporting. This shift highlights a move toward greater operational efficiency, collaboration, and alignment with modern industry practices.


Led by CEO Jason Churchill, PetroLegacy Energy (PLE) completed its full transition to ComboCurve in 2023, fully integrating the platform into its reserves and A&D workflows. This shift, which marked the end of their reliance on ARIES, brought significant improvements in operational efficiency, decision-making speed, and cost savings. After initially adopting ComboCurve in 2020 for A&D evaluations, PLE phased out legacy systems over three years, ultimately streamlining their entire process. The full adoption of ComboCurve enabled PLE to reduce evaluation time drastically, accelerate deal assessments, and eliminate costly software licenses, positioning the company for faster growth and more data-driven decisions.

“It’s been so long since I’ve been in ARIES that it’s hard for me to even recall the frustrations of using it. The value that I see in ComboCurve lies in its ability to facilitate real-time collaboration, standardize our processes, and help us reach decisions faster. It’s become an essential part of how we work.” – Jason Churchill, CEO, PetroLegacy Energy

From Gradual Adoption to Full Integration

PLE first adopted ComboCurve in 2020 for A&D evaluations while continuing to rely on ARIES for reserves management. The initial hesitation wasn’t due to ComboCurve’s limitations but stemmed from compatibility concerns with external auditors, banks, and investment partners, many of whom were still reliant upon ARIES. This meant that PLE faced challenges inherent to legacy workflows that required data to be pushed between multiple environments– creating time delays in managing investment decisions and reserves management.

However, by 2023, those barriers had faded.

“We accomplished the goal of managing all of it in ComboCurve. From what we could tell, people were either becoming ComboCurve users themselves, where we could simply send them sharecodes to access our database,” Jason explains, “or we became adept enough to accurately convert & submit our data into a traditional ARIES format.”

As more industry stakeholders adopted ComboCurve and embraced its cloud-based platform, PLE transitioned entirely to ComboCurve, retiring their ARIES licenses. This shift not only eliminated time-consuming database conversions but also created an integrated, streamlined workflow.

Key Benefits of the Transition 

  1. Cloud-Based Collaboration
    One of the biggest advantages of ComboCurve for PLE has been its ability to support remote, simultaneous collaboration across teams. Unlike ARIES, which is tied to individual desktops, ComboCurve’s web-based platform eliminates the frustration of locked files and restricted access. This real-time collaboration improves communication, reduces delays, and allows PLE to remain agile in their decision-making.

“Aaron and I can open the same project – not even sharing screens – and we can QC a project together, interrogate data, and make changes on the fly, simultaneously from anywhere. That alone has been hugely beneficial.” – JC

  1. Unified Reserves and A&D Workflows
    Integrating reserves and A&D evaluations within a single platform reduced the friction of exporting and importing data between systems. PLE could now manage everything from reserves forecasting to deal evaluations in ComboCurve, enabling faster updates and more seamless decision-making processes.“We had them in different environments and had to push data over to ARIES at certain times to carry out updates.

“It’s just easier to have the data flowing into one place. I’m able to update it very quickly from there instead of having to take that data somewhere else.” – JC

  1. Faster Screening and Scoping
    By reconfiguring their ComboCurve database to operate at the company level, PLE drastically reduced the time required for project screening. What used to take days in ARIES could now be completed in a matter of hours. This speed allowed PLE to evaluate deals more efficiently, increasing their ability to act on opportunities.“Historically, that might have taken a couple of days in ARIES. With ComboCurve, from the company level, we can pull down what we need into a project, screen, and scope something in just a couple of hours.

“The mapping capabilities are a game-changer – zooming in, filtering, and grabbing exactly what we need makes ComboCurve a powerful screening environment.” – JC

With ComboCurve fully integrated into their operations, PLE continues to focus on standardizing workflows across the company. They are working to refine how projects are set up and managed, creating consistency in their data and forecasts. These improvements will allow them to make even faster data-driven decisions while maintaining a high level of accuracy and control.

Driving Industry Adoption

As more third-party auditors and banks transition to ComboCurve, traditional tools like ARIES are becoming less relevant. PLE’s shift to ComboCurve aligns with a broader trend of industry adoption, further automating workflows and eliminating time-consuming manual data tasks.

This transition highlights how Combo Curve, a modern, cloud-based platform redefines reserves and A&D processes. By unifying workflows and enabling real-time collaboration, teams can collaborate,  assess project viability, analyze well performance, and make informed, data-driven decisions– all while setting new standards for industry best practices.
