PE Limited: A Unified Approach to Cost-Effective Upstream Operations

Maximising hydrocarbon recovery in a clean, efficient and economical manner within the upstream oil and gas sector is non-negotiable. It demands a unified, physics-based system built for end-to-end lifecycle integration—where PE Limited (Petex) has set the benchmark. At the core of its offering are the IPM and DOF platforms, enabling operators to model, monitor and optimise performance across the entire production lifecycle.

Its 18 world-class modelling tools are designed to interoperate seamlessly, grounded in shared physics, consistent data assumptions and unified architecture. This allows production teams to precisely manage a hydrocarbon molecule’s journey from reservoir to export.

That journey begins with geological modelling using MOVE, which incorporates well logs and seismic data to validate and model the subsurface structures which have generated, stored and trapped the hydrocarbons. This end to end system requires fluid flow one end to the other. PVTp used to ensure that the fluid properties are accurately represented at each condition throughout its journey. MBAL then supports material balance calculations for understanding hydrocarbons in place, aquifer drive and depletion, while REVEAL, PE Limited’s full field, fully thermal integrated reservoir simulator, combines traditional reservoir modelling and specialised reservoir studies. When production starts, PROSPER models the wells and GAP/GAP Transient handles the surface network, flow and optimisation.

RESOLVE enhances this end-to-end modelling, enabling integration of third-party software into the ecosystem. Once production is underway, the DOF platform connects real-time sensor data with these physics-based models to drive automated visualisation and operational workflows.

“The strength of our suite lies in how each tool seamlessly integrates, built on a foundation of consistent data and physics. This results in a system that mirrors the evolving behaviour of the reservoir in real-time,” says Greg Grimshaw, CEO of PE Limited.

Adaptability in Action

The strength of PE Limited’s IPM and DOF platforms lies in their flexibility to handle the diverse and complex realities of oil and gas operations, from deepwater assets in Brazil to high-pressure gas fields in Southeast Asia and shale plays in North America. The tools are engineered to tackle challenges through geographic customisation and robust configurability that adapts to each reservoir’s unique conditions.

With over 500 global customers and thousands of success stories, the platforms’ impact is clear. A national oil company in the Middle East saw a 200,000-barrel-per-day production increase, while an operator in Brazil gained 6,000 additional barrels per day by resolving flow assurance issues. In the U.S., even mature asset operators reported a 4 per cent production boost after adopting DOF.

This level of improvement reflects PE Limited’s commitment to long-term partnerships. Beyond software, it offers real-time support, technical workshops and collaborative problem-solving. Structured engagements, like its annual user group meeting in May and virtual check-ins each November, allow clients to influence platform development and share best practices across the community.

A Continuous Path to Optimisation

A key strength of PE Limited lies in optimising operations at the ground level, where the integration of real-time sensor data with predictive modelling proves especially powerful. As field conditions shift, the system recalibrates, enabling swift, informed decisions that boost efficiency and reduce risk.

This capability is critical amid growing pressure for cost control and sustainability. Operators using IPM and DOF platforms report 6 to 17 per cent of production qualifying as “low-cost oil”—a sharp rise from the typical 2 per cent seen with fragmented systems. For large-scale operations, these gains translate into significant economic and environmental value.

Building on its foundation of efficiency and impact, PE Limited is embedding AI across its platform to accelerate analysis, refine modelling and support faster, smarter decisions.

At the same time, its Lab 22 (thelab22) initiative is helping shape the future of STEM by funding the teaching of modern science in classrooms and laboratories at its Head Office, in the UK. This effort to inspire young minds is complemented by ongoing support for global charities, such as UNICEF and Diabetes UK, reflecting a broader vision that blends technical innovation with lasting social impact.
The future of upstream production belongs to intelligent, integrated systems, not fragmented tools or reactive fixes. PE Limited brings this future to life with platforms rooted in physics, powered by engineering and driven by real-time collaboration. Rather than keeping pace with change, it is setting the direction.
