How BPX Energy managed a $10.5 billion acquisition on a platform they already trusted.
When BPX Energy acquired BHP’s U.S. onshore assets for $10.5 billion, it needed to retire a legacy system, consolidate operations across a vast portfolio, and maintain complete data integrity throughout. All of it delivered in-house, against a tight deadline.
They didn’t need to find a platform they could trust. They already had one.
The foundation: production accounting across 10,000 wells
BPX Energy is bp’s U.S. upstream subsidiary, focused on onshore oil and gas production across the Lower 48 states. Before the BHP acquisition, BPX were already running their existing portfolio on EnergySys: production accounting for approximately 10,000 onshore gas and liquid wells, spread across six operating areas in North America.
That deployment had replaced Energy Components, bp’s previous data management system. Energy Components was costly to run and, more critically, costly and slow to enhance and update. BPX needed something their own team could configure and adapt without going back to a vendor every time something changed.
EnergySys gave them that. The team built and managed their production accounting environment themselves, across a portfolio of significant scale and complexity.
”I couldn't be more pleased with our decision to implement EnergySys. The cloud platform and flexible interface is exactly what we needed to keep up with our dynamic operating teams. The EnergySys team performed remarkably during a tight integration timeline. And since then, they've been there whenever we've needed any help. Their direct and immediate support model truly sets them apart."

The acquisition: a $10.5 billion deal, a tight deadline, and no room for a slow start
In 2018, bp acquired BHP’s U.S. onshore assets for $10.5 billion, one of the largest onshore asset acquisitions in recent U.S. energy history. BPX Energy took on the integration.
The challenge was substantial. BHP’s legacy production data systems needed to be retired quickly. Operations needed to be consolidated without disruption. Data integrity had to be maintained throughout. And the entire project needed to be delivered internally, without third-party system integrators.
For many operators, that combination of scale, speed, and complexity would have meant a lengthy procurement process, a new system, and months of parallel running.
BPX didn’t need any of that.
The integration: reuse, refine, roll out
Because EnergySys was already embedded across BPX’s existing Lower 48 operations, the path forward was straightforward. The team spun up a new EnergySys instance using the same configuration as their existing setup.
No starting from scratch. No new vendor relationship to manage. No third-party integrators. A small number of targeted adjustments to accommodate the BHP asset data model and the integration were underway.
The low-code, configurable architecture meant BPX’s own team handled everything from start to finish, with full control over the process and the data throughout.
The result was a clean cutover with no operational disruption, legacy systems retired on schedule, and complete data integrity maintained across the full portfolio.
Outcomes: post-acquisition integration delivered in weeks
- Production accounting running across approximately 10,000 onshore gas and liquid wells in six operating areas, on a platform BPX’s team own and manage themselves.
- A $10.5 billion acquisition integrated using an existing EnergySys configuration, with no third-party integrators and no new system procurement.
- Legacy BHP production data systems retired rapidly, with a clean cutover and no operational disruption.
- Complete data integrity maintained throughout the post-acquisition integration.
- The entire project delivered by a small internal team, on time.
The bottom line.
BPX Energy didn’t manage a $10.5 billion acquisition by finding the right platform under pressure. They managed it because the right platform was already there.
A team that had spent years configuring and running EnergySys across their existing portfolio could spin up a new instance, adapt it to a new asset model, and deliver a clean integration without external help. The platform didn’t need proving. The team didn’t need onboarding. They just got on with it.
That is what it looks like when a platform is genuinely embedded in the way a business operates.
