Advanced gas leak survey & Data Analytics

Southern Cross’ advanced gas leak detection technology includes advanced instrumentation consisting of a highly sensitive detector PPB (x1000 times more sensitive than conventional gas leak detectors) and a comprehensive data collection and analytics platform for leak and emissions detection and management.

As a result, the system finds more gas leaks and pinpoints “hard-to-locate” gas leaks and is able to survey and fix entire neighborhoods at once with multiple crews in a shorter timeframe than traditional gas leak survey methods. By quickly surveying an entire neighborhood with our advanced gas leak detection system, a holistic view of all sources of methane in the area quickly provides data and enables survey technicians to hone in on the exact location of the leak rather than be overwhelmed by leak indications within or on the edges of the migration pattern.
The advanced gas leak detection system measures atmospheric and meteorological conditions, methane plume signatures and uses dynamic algorithms to compute the likely location and emissions rates of natural gas leaks while screening out false positive indications. It combines information from multiple measurement sessions run over the same region, taking advantage of varying atmospheric conditions (wind direction, wind speed, atmospheric stability) to produce aggregate results and to provide comprehensive territory coverage.

Environmental and emissions reduction programs

This innovative technology is setting the precedent for Advanced Mobile Leak Detection and is changing the way we view leak survey by providing faster more reliable data that can be utilized to solve a multitude of issues for our providers including safety, emissions reductions, and quality.

Using the same technology platform, Southern Cross will be able to assist our partners in their methane emissions reduction programs by providing capabilities for measuring flow rates and Ethane quantification capabilities. Using Methane Emissions Quantification measurements and big data analytics, Southern Cross can provide our partners with a comprehensive and actionable set of emissions metrics to accelerate methane emissions reductions in their territory.

Emissions measurements allow the highest-emitting leaks to be identified andtargeted for expedited repair so as to gain the most benefit in methane reductions from leak repair activities (above and beyond repairs from leaks found by compliance survey or leaks
removed by pipe replacement).
