It turned out that the amount of methane released by a general developed country in one year leaked in an American gas field accident
A research result was announced that the total amount of methane leaked from the gas field accident that occurred in Ohio, USA in February 2018, corresponds to the amount released in one year by European countries except the UK and Germany .

The gas field accident in question occurred on 15 February 2019 in an XTO energy gas field located near the state border between Ohio and West Virginia. The accidental leak continued for 20 days and continued to release methane-containing gases that had a greenhouse effect 25 times that of carbon dioxide. Below is the video at the time of the accident. Black smoke rises on a large scale so that it can be seen at a glance from the mountains.

A research team led by Dr. Sudhanshu Pandey of the Netherlands Space Research Institute (SRON) uses the data of the new satellite `` Sentinel-5P '' of the European Space Agency (ESA) that can identify methane with a high resolution of about 7 km, at the time of the accident A simulation of weather conditions was performed to calculate the total methane leakage.
The leak lasted for 20 days, but there were only two clear days that Sentinel-5P could observe the ground, so there are considerable errors in the calculations. As a result of calculations including corrections by simulation, the research team estimated that methane leakage due to the accident in question was 98 to 152 tons per hour. The total amount of methane leakage for 20 days, calculated based on this estimate, will be about 45,000 to 75,000 tons in total. The research team expresses this total spillage as “equivalent to one year's methane emissions from oil and natural gas in European countries”.

The gas field accident in Ohio sheds light on important facts about methane leaks. That is the fact that drilling facilities, called “superemitters”, are particularly severe, accounting for the majority of the total leakage. Research results have also been announced that drilling facilities in the top 10% of leaks discharge 77% of total leaks.
In the research announced this time, the research team said, “With a satellite like Sentinel-5P, it is not necessary to inspect the machine for“ leakage due to malfunction ”. The superemitter is identified by itself because it monitors me. '
