Project description

 Over the last couple of years, important work has been performed in particular in North America to understand emissions patterns, develop and refine emissions factors and evaluate the cost effectiveness of mitigation options.

 Compared to North America, fewer public studies have focused on measurement of methane emissions from oil and gas systems in Europe. To close this gap, Carbon Limits provides here some insight on emission patterns in Europe focusing particularly on midstream emissions, but also sheds new lights on a few critical issues related to methane emissions mitigation. In particular, the study aims at answering the following questions:

 • What is the distribution of emission rates, and how do rates vary based on the type of components?

 • When operators detect a leak, they typically perform a repair. How effective are these repairs at reducing the emissions?

 • How frequently are new leaks detected after repair, and how often does repaired equipment leak again?

 To answer these questions Carbon Limits performed some statistical analyses based on ca. 800 000 data points collected during surveys carried out by three private sector firms providing emission detection and measurement services to the industry.

 A webinar was held on December 11th, 2017.
