Pre-Conference Workshop Day: Tuesday 16th March

8:30 AM Workshop B: From Data to Defensibility: Improving Methane Measurement, Statistical Confidence and Reconciliation

Methane quantification is still an evolving field, particularly across midstream and downstream operations, where operators must balance reporting quality, cost and practical site constraints. As measurement approaches become more sophisticated, questions remain around the reliability of leak-rate assumptions, the treatment of uncertainty and the comparability of results generated through different methodologies.

This workshop will bring together practitioners to examine how methane inventories can be made more robust, transparent and fit for purpose, from source-level measurement through to site-level balances and reconciliation.

• Leak-rate distributions and uncertainty: How should operators account for the variability of emissions sources when calculating confidence intervals and reporting total emissions?

• Reconciling different datasets: What are the main barriers to reconciling source-level measurements, site-level estimates and wider inventory calculations — and how can statistical methods improve confidence in the results?

• Reporting quality versus reporting cost: Which approaches provide the strongest improvement in accuracy relative to the resources required, and how should operators prioritise investment in quantification?

• Beyond standard methodologies: Where do established approaches and default emission factors fall short, particularly across European midstream and downstream facilities?

• Emerging source-level measurement tools: How can technologies such as high-flow samplers improve quantification and address gaps in existing methodologies?

• Capturing the emissions that matter most: How can operators identify potentially underestimated high-emitting sources, including valves and safety relief devices, and ensure these are appropriately represented in methane inventories?
