Oil and gas has never been short of pressure. Volatile markets, shifting regulations, and tighter margins are nothing new. But the pace of change is growing.

According to Deloitte’s 2026 Oil and Gas Industry Outlook, nearly 70% of US oil and gas companies plan to restructure portfolios, optimise costs, and divest non-core assets. That level of portfolio activity puts real strain on operational systems. 

PwC’s 2026 energy deals analysis points to renewed momentum in gas and LNG, with acquisitions and midstream integration reshaping portfolios across the sector.

Portfolios grow, contract, and shift. New asset types appear. Regulations evolve. The tools many teams rely on were not built to keep up.

What legacy systems are actually costing you

The case for staying with on-premises software often comes down to sunk cost. The system is paid for. It works, more or less. Change feels risky.

What that calculation misses is everything happening around the edges. Ageing systems need bespoke support. Fragmented tools create fragmented data. Teams build workarounds: spreadsheets, side applications, manual processes. These introduce risk and consume time. None of these costs appear on a maintenance invoice.

Upgrades compound the problem. On-premises systems can require major projects every few years. Consultants, hardware, user retraining. The disruption is significant. The output is often just getting back to where you were.

A system that cannot adapt quickly enough stops being an asset. It becomes a constraint.

Why cloud changes the equation

Cloud-native platforms are built for change. They scale as operations shift. No capital investment, no lengthy procurement cycles. Updates are delivered regularly, without upgrade projects or downtime. Security and compliance are maintained as part of the service.

For oil and gas operators, the practical benefits are clear. Production reporting, allocation models, reserves data, and planning workflows can all sit in one auditable environment. Data has one home. Teams work from the same numbers. The manual reconciliation that consumes hours each month becomes unnecessary.

The shift does not have to happen all at once. A phased approach, starting with the highest-impact areas, means value arrives quickly without the disruption of a full system replacement.

You do not have to do this alone

The most common blocker to cloud adoption is not budget or appetite. It is internal resource. Change projects take time and expertise that most operational teams do not have spare.

This is where partners come in.

EnergySys works with a network of experienced partners spanning specialist boutique consultancies, global systems integrators, and regional implementation experts. Whatever the size or shape of the project, there’s likely to be a partner who has solved something close to it before.

On the specialist side, Accord is an independent hydrocarbon accounting consultancy that’s been building on EnergySys since 2017, with over 30 implementations across Europe, Asia, Africa, the US, and Australia. Kelton brings 30 years of flow measurement expertise, most recently as the first licensed reseller of their own KCCL calculation library through EnergySys. CarbonOptics focuses entirely on emissions, helping operators navigate Australia’s NGER scheme and Safeguard Mechanism from the same platform that runs their production data. And Equity Lifting Solutions brings deep commercial expertise in LNG lifting and marketing structures, drawn from some of Australia’s largest gas projects.

For operators running large, multi-geography programmes, Infosys and Wipro bring enterprise-scale delivery capability and their own dedicated hydrocarbon accounting practices, backed by the reach to staff and support projects globally without juggling multiple local vendors.

And in newer markets, TechxSA in Malaysia, Quadface in India, and Incendo in New Zealand are extending EnergySys’s reach with local teams who understand the region’s operators directly.

Elite Energy works directly with operators to design, build, and implement EnergySys solutions. Their approach is built around knowledge transfer: by the end of a project, the operator’s own team has full capability to run and adapt the system themselves, a model several partners in the network share.

An operator does not need an internal development team to get started. They can rely on a partner. Someone who has solved the same problems before and can configure a solution around how the business actually works.

The results speak for themselves. BPX Energy took on BHP’s $10.5 billion US onshore asset acquisition by reusing the EnergySys configuration they already had, with no third-party integrators, delivering the entire post-acquisition integration in weeks rather than months. Integration work that might have taken years was done in a fraction of the time.

The case for acting now

The producers best placed in the years ahead won’t simply be the largest or the best-resourced. They’ll be the ones whose systems can keep up with change.

Cloud is not a future state. For a growing number of operators, it is already how they run their business. The question is not whether to make the move. It is how to make it well, and who to make it with.
