Reducing methane emissions from oil and gas facilities is important for fighting climate change. A study in Canada measured the effectiveness of leak detection and repair surveys at reducing methane leaks. They found that after one survey, total emissions decreased by 44%, with a 22% reduction in leaks and a 47% reduction in vented emissions. Most leaks found in the first survey were fixed by the second survey, but new leaks appeared. Tank-related emissions played a significant role in overall emissions. The study suggests that frequent and low-cost surveys are needed to target new leaks and that specific strategies for tanks can help reduce methane emissions from the oil and gas industry.
