Introduction
Methane emissions management in oil and gas breaks down when a facility reports vented, fugitive and flared volumes from generic factors that no survey has ever tested, while leaks, unlit flares and bleeding pneumatic controllers keep releasing gas that could be sold. Buyers, investors and reporting programmes now ask for measured, reconciled figures. This Core Concept course trains engineers to map methane sources, quantify them at source and site level, run LDAR and optical gas imaging surveys, report against OGMP 2.0 and choose cost-ranked abatement. Participants build a Facility Methane Inventory and Reduction Roadmap.
Course Objectives
- Map methane emission sources across production, processing, transmission and storage assets by venting, flaring, fugitive, pneumatic and tank category
- Quantify facility methane with emission factors, engineering calculations and direct measurement, and reconcile source-level totals with site-level measurements
- Design an LDAR programme with component inventories, survey frequencies, detection thresholds, repair deadlines and record keeping
- Plan and conduct optical gas imaging surveys and select drone, aircraft, satellite or continuous monitoring for the right detection task
- Prepare methane reporting to OGMP 2.0 reporting levels and gather the evidence a certification audit such as MiQ grading expects
- Rank abatement options such as flare gas recovery, vapour recovery units and zero-bleed pneumatics in a costed methane reduction roadmap
Target Audience
- Environmental engineering staff who compile facility emission inventories and methane reports
- Operations and production engineering staff who run wells, separators, compressors, tanks and flares
- Emissions and LDAR programme staff who schedule surveys, track leaks and verify repairs
- Mechanical, instrumentation and integrity staff who maintain valves, seals, pneumatic controllers and vapour recovery equipment
- Field technicians and survey contractors who carry out optical gas imaging and leak quantification work

Why Attend This Course
- Return with a Facility Methane Inventory and Reduction Roadmap built from realistic production and compression station data
- Stop relying on untested emission factors by knowing which measurement method fits each source and site
- Find and fix the few large leaks and unlit flares that drive most of a facility's methane before an aerial or satellite survey does
- Compare leak survey and abatement practice with engineers from upstream, midstream, gas processing and LNG operations
Conclusion
Methane falls only when a facility knows where its gas escapes, how much leaves each source and which fix pays back first. The five days move from source mapping across the value chain, through emission factors, source-level and site-level measurement and OGMP 2.0 reporting, to LDAR design, optical gas imaging practice, aerial and satellite detection and abatement engineering. The final day turns this into a Facility Methane Inventory and Reduction Roadmap that participants can apply at their own sites.
