Gas Flaring

Reinjection for disposal or storage can be viable, and so too can reinjection to support ongoing oilfield operations with pressure support. 

There are also technologies and maintenance practices to improve the efficiency of existing flares. For example, using flare tips with more modern designs that improve fuel and air mixing, or converting to flare stacks that ensure adequate fuel–air mixing to consistently achieve very high combustion efficiencies, can significantly reduce emissions resulting from poor combustion efficiency.  

Operators that sell high-flaring assets are often passing on a problem to other operators that may be less willing, or less able, to cut down on flaring

A recent study from the Environmental Defense Fund on oil and gas industry mergers and acquisitions showed that asset value is increasingly moving from publicly listed companies with stronger climate commitments to private actors with weaker standards. In 2020, Rystad Energy found that private enterprises operating in the Permian basin flared at levels six times the intensity of publicly held counterparts.  

Several international initiatives have been launched to reduce methane emissions from flaring

The Global Gas Flaring Reduction Partnership is a public–private initiative made up of national and international oil companies, national and regional governments, and international institutions. The partnership aims to increase the use of natural gas associated with oil production by helping to remove technical and regulatory barriers to flaring reduction, conducting research, disseminating best practices and developing country-specific gas flaring reduction programmes. 

Various energy companies, governments and institutions have endorsed the Zero Routine Flaring by 2030 initiative launched by the World Bank and the United Nations in 2015. For new fields, this scheme encourages operators to develop plans to use or conserve all the field’s associated gas without nonemergency flaring. For existing fields, operators are asked to eliminate nonemergency flaring as soon as possible, and no later than 2030.
