Building Production Confidence in Northern Territory Offshore Operations

Every production decision starts with confidence in the data behind it.

For offshore oil and gas operators in the Northern Territory, reliable production data underpins reservoir management, production optimisation, asset planning, forecasting, and regulatory reporting. When production measurements are uncertain, it becomes more difficult to optimise performance, identify opportunities, and make informed operational decisions.

As offshore fields mature and production conditions evolve, maintaining confidence in flow measurement systems becomes increasingly important. Independent verification can help reduce uncertainty, validate measurement performance, and provide greater visibility into how assets are performing.

Why Production Confidence Matters

Accurate production measurement is about more than reporting volumes. It provides the insight operators need to:

• Optimise production across offshore assets
• Monitor well performance and identify changes early
• Improve reservoir management and field development planning
• Support reliable production forecasting and allocation
• Reduce operational risk and uncertainty
• Strengthen compliance and reporting confidence

When operators have confidence in their production data, they can make faster, more informed decisions that support production performance, operational efficiency, and asset value.

Overcoming Production Measurement Challenges

Many Northern Territory offshore assets rely on Wet Gas Meters (WGM) and Multiphase Flow Meters (MPFM) to monitor production performance. While these technologies provide valuable production insights, changing reservoir conditions, shifting fluid characteristics, and ageing infrastructure can impact measurement confidence over time.

For operators without readily available test separator capacity, independently verifying production data can be challenging. This can create uncertainty around production rates, meter performance, and the information used to support critical operational and investment decisions.

The challenge is not simply measuring production but ensuring the data remains reliable enough to support confident decision-making throughout the life of the asset.

Independent Verification Without Disruption

SGS Multiphase Tracer Testing (MPTT) helps operators independently verify gas, condensate and water production rates directly from the production stream.

Unlike traditional testing methods, MPTT is non-intrusive and can be performed without production shutdowns, separator facilities, or flowline modifications. This allows operators to validate production measurements while maintaining normal operations and avoiding unnecessary disruption.

By independently verifying production data, operators can:

• Improve confidence in production reporting
• Validate WGM and MPFM performance
• Support production optimisation initiatives
• Reduce uncertainty in reservoir and production management decisions
• Maintain production continuity during testing activities
• Gain greater visibility into actual asset performance

The result is improved measurement certainty and the confidence to make decisions based on trusted data.

Supporting Better Production Outcomes

Independent measurement verification delivers benefits beyond measurement accuracy.

When production data can be validated independently, operators gain a clearer understanding of well performance and production behaviour. This supports more effective production optimisation, improved operational efficiency, and better planning for future field activities.

For production and reservoir teams, reliable verification data can help identify production opportunities, support troubleshooting efforts, and provide greater confidence in forecasting and allocation models.

Ultimately, this helps reduce uncertainty and enables a more proactive approach to asset management.

Proven Results

In an offshore production verification project, we compared MPTT measurements with existing wet gas meter data across multiple wells.

The results demonstrated strong agreement between the two measurement methods:

• Gas variance: 0.36%
• Condensate variance: 1.67%
• Water variance: 4.61%

For the operator, these results provided confidence in existing production measurements, supporting continued optimisation activities and informed operational decision-making.

Why Offshore Operators Partner with SGS

We combine independent measurement expertise, laboratory capability, and technical experience to help offshore operators improve confidence in production data.

Our certified Multiphase Tracer Testing methodology provides an independent and proven approach to verifying gas, condensate, and water production rates without interrupting operations.

Whether supporting flow meter verification, production testing, reservoir management initiatives, or production optimisation programs, we help operators reduce uncertainty and make better business decisions based on trusted information.

Supporting Northern Territory Offshore Operations

For Northern Territory offshore operators, production confidence is more than a measurement challenge, it's a business requirement.

Reliable production data supports better forecasting, improved production optimisation, more efficient operations, and stronger decision-making across the asset lifecycle.

By independently verifying production performance, we help operators gain greater confidence in their measurement systems, improve visibility into asset performance, and make informed decisions that maximise operational value.
