From acquisition to automation: how TAQA built a decade of hydrocarbon accounting on EnergySys.
After acquiring new assets in the North Sea, including the Brent Pipeline system, TAQA found itself in a high-stakes race against time.
Challenge: a system that couldn’t keep up, and no time to wait
The acquisition brought complexity with it. The inherited hydrocarbon accounting system wasn’t just outdated. It was incapable of handling the infrastructure TAQA had just taken on.
Five platforms. Over 30 fields, 13 of them operated. More than 175 wells. And a new responsibility as Brent Pipeline Operator, managing Fuel Gas purchases for gas-deficient fields across the Brent pipeline area.
The options weren’t appealing. Pay to upgrade the legacy system, extend the licence, and absorb the risk. Or replace it entirely, in a matter of months.
TAQA also needed their production allocation solution to work alongside OFM, the tool their team uses to manage and improve field performance. That meant handling different naming conventions across two systems automatically and keeping everything in sync with a fast-moving drilling schedule.
What they needed was a system they could deploy quickly, configure themselves, and own from day one.
Solution: deployed fast, then built for the long term
TAQA selected the EnergySys Cloud Platform as the solution best placed to meet their deadline.
The platform was configured and running within the critical window. Allocation logic was tailored to their asset mix. Reporting was consistent across both legacy and new assets. And crucially, TAQA’s own team handled it all without waiting on a vendor or raising an IT ticket.
The EnergySys and OFM integration was configured to resolve naming convention differences between the two systems automatically. Keeping both in sync with an active drilling schedule became a routine process, not a manual reconciliation exercise.
That self-sufficiency didn’t stop at go-live. With the platform in their hands from the start, TAQA’s team kept building. Over time, they took automation further. Participants can now email data directly to the system. On receipt, validation and calculation processes run automatically. The Hydrocarbon Accountant can monitor the entire workflow, from data arriving in the inbox to final allocation, without leaving the platform.
The system also expanded beyond the core accounting team. Reservoir Engineers, Process Engineers, and Commercial colleagues can all access and use data appropriate to their role, directly in the platform or through reports, without needing to chase outputs or request extracts.
”We configure and manage everything ourselves. That's what sets EnergySys apart from other systems. What we've done, and how quickly we've done it, would not have been possible with any other tool.

Outcomes: a decade of depth
The initial deployment met the deadline. That was the start, not the finish.
Over more than ten years on the platform, TAQA has built an operation that would be difficult to replicate on a less flexible system.
- A high-pressure post-acquisition deployment completed on time, with full data confidence from day one.
- Allocation models for complex offshore assets and the Brent Pipeline, fully configured and maintained by TAQA’s internal team.
- OFM integration handling naming convention differences automatically, keeping both systems in sync across an active drilling schedule.
- Data receipt, validation, calculation, and reporting running automatically, monitored end-to-end by email.
- Multiple departments accessing the data they need, in the format they need it, without creating dependencies on a central team.
- Every change, calculation, and output logged and audit-ready.
The transition that could have been chaotic became a foundation. The team that deployed under pressure became self-sufficient. The system that met a deadline kept growing with the business.
The bottom line.
TAQA needed to move fast. They did. Then they kept going.
More than a decade on, they run one of the North Sea’s most automated hydrocarbon accounting operations, owned and evolved entirely by their own team. When something needs to change, they change it. When a regulator or a joint venture partner asks a question, the answer is there.
That is what it looks like when a platform becomes part of how a business operates, not just a tool it uses.
