Research: oil and gas production emits more methane than previously thought

According to a new study from the Harvard School of Engineering and Applied Sciences (SEAS), the conservation agency

Environmental Protection Agency (EPA) US downplays emissionsmethane from oil and gas production in its annual report. The team of researchers found that emissions from oil production are 90% higher and from natural gas production 50% higher than EPA estimates.

Research team led byJoannes Masackers, a former SEAS graduate student, has developed a method for tracking and mapping total emissions using satellite data. So far, the data only relate to emissions across the United States, but the researchers plan to calculate emissions for individual states of the country.

Scientists have compared these models to satelliteobservations in 2010-2015. Using a transport model, they were able to trace the path of atmospheric emissions and identify areas throughout the United States where observations and simulations did not match.

“When we see emissions from space, we cansee only how the total emissions from a particular area are exaggerated or underestimated, but we do not know the source responsible for these emissions. Since we spent so much time with the EPA figuring out where the various emissions are occurring, we could use our transport model to go back and find out which sources are responsible for these underestimated or overestimated nationally, ”the scientists noted.

They also calculated emissions based on mining processes and equipment. They noticed the largest discrepancy in emissions from oil and natural gas production.
