Case Studies

The last part of this Toolkit presents recent developments and case studies of policy actions and technologies driving methane mitigation efforts. They illustrate how improvements in methane management have been achieved in different contexts and explore three key issues: (i) how to develop an effective policy approach; (ii) which tools and strategies have been successfully deployed to monitor emissions; and (iii) what are some of the leading abatement technologies being deployed across different industry segments.

These case studies show how policies and regulations can drive methane abatement. They cover experiences of jurisdictions in different stages of policy development, offering insights on how to tailor mitigation efforts to the resources and characteristics of each setting.

Colombia becomes first South American country to regulate methane from oil and gas

On 11 February 2022, the Colombian Ministry of Mines and Energy finalised its flaring and fugitive methane emissions regulations, which aim to reduce fugitive emissions from upstream oil and gas activities at a national level – making it the first South American nation to regulate methane emissions from oil and gas. This case study presents the steps taken to achieve this milestone and the major components of this legislation.

Western Canada: addressing infrastructure barriers

Canada has set an ambitious target: at least 75% reduction in oil and gas sector methane emissions from 2012 to 2030. To accelerate methane abatement in line with this goal, Canada is advancing policy measures and regulatory requirements for methane emissions reductions in the oil and gas sector. This case study presents one of these measures – Natural Resource Canada’s Emissions Reduction Fund – that supports investments in green technologies and infrastructure to reduce methane emissions from existing and already-scheduled oil and gas production.

A comprehensive assessment of methane emissions in the Permian basin: the PermianMAP project

Environmental Defense Fund’s (EDF’s) Permian Methane Analysis Project (PermianMAP) was a methane monitoring and research project aimed at providing transparent and accessible methane emissions data from one of the world’s largest oil fields. The project was designed to use a variety of peer-reviewed advanced techniques to monitor and quantify emissions, including: satellite-based regional estimates; ground-based vehicle measurements and helicopter-mounted optical gas imaging; stationary measurement towers and periodic aircraft mass balance flights; and aircraft hyperspectral imaging. Resulting data was made available on a public website within days to weeks after data collection, as opposed to most scientific peer-reviewed efforts which take months to years.

Continuous monitoring systems: NextDecade and Project Canary

In 2021, NextDecade and Project Canary started a joint pilot project for monitoring, reporting, and independent third-party emissions measurement and facility certification of greenhouse gas intensity of LNG to be sold from NextDecade’s planned Rio Grande LNG export facility. The joint pilot project will measure emissions across the value chain through Canary X and Aeris continuous emissions monitoring devices, and use TrustWell™ and other certification processes to confirm emissions levels of each element of the natural gas value chain – from the wellhead to the ship at Rio Grande LNG.

Detecting and quantifying gas distribution leaks across cities in North America and Europe

Measurement campaigns have suggested that actual emissions across different end-use environments are often underestimated, including in cities and households. Mobile measurement platforms are one of the tools that have been used to characterise emissions from local distribution networks. These methods can quickly survey large urban areas, identify leaks, quantify the emissions distribution and support estimates of total emissions from distribution networks. This case study provides further details on such efforts to detect and quantify methane leaks in urban areas.

Measurement efforts uncover mitigation priorities: discrepancies in onshore & offshore emissions in Mexico

Mexico’s emissions inventories have been based in simple emission factors (i.e., IPCC Tier 1), and changes in the estimation methods have resulted in significant changes in emission estimates over the past decade. This makes it impossible to track changes in emissions as well as mitigation progress. A recent study quantified methane emissions from Mexico’s most important onshore and offshore oil and gas production regions using aircraft-based measurements and satellite data (TROPOMI and VIIRS night-time flare data).  This study illustrated how satellite data can be used to independently assess the representativeness of other temporally discrete sampling approaches (i.e., aircraft) with respect to annualised emission rates—thus reconciling these estimates. A follow-up study integrated roughly two years of TROPOMI data to characterise and quantify methane emissions, by sector, for the majority of the country.

Baker Hughes and bp: Reducing methane slips from flaring – Flare.IQ

Flares are an essential safety device that enable gas to be disposed of when a part of an oil and gas facility has to be shut down suddenly. Operators and regulators recognise the importance of achieving high combustion efficiency of flare gas in order to reduce methane emissions. When properly burnt off, the gas converts to carbon dioxide and prevents raw methane from entering the atmosphere via the flare stack. The combustion efficiency of flares should be at the level of 98% or higher. This case study shows how bp is using Flare.IQ (from Baker Hughes) to better understand, measure and ultimately reduce methane emissions associated with flares.

GRTgaz: Abating vented emissions in transmission networks

This case study describes different solutions deployed by GRTgaz to reduce venting on its transmission network, to recover or reduce pipeline maintenance vents, compressors vents and even smaller vents on delivery stations. These solutions enabled GRTgaz to save more than 90% of the gas that would otherwise have been vented since 2018. On compression stations, a specifically-designed mobile recompression technology addresses intermediate-sized volumes. In addition, when recovery is not yet possible, a mobile blue flare stack is used to address vents. GRTgaz also implemented a specific multi-year investment plan to eliminate vent leaks and use gas resulting from depressurizations​. Finally, GRTgaz developed a solution for maintenance activities on delivery stations, to enable the decompression of a station by dumping the volume of gas in another working pipeline.
