COVID-19 impact on the oil and gas industry emissions: a case study of
methane and nitrogen dioxide in the Permian basin
Abstract
COVID-19 caused an historic collapse in fossil fuel demand, a general
decline in economic activity and hydrocarbon price volatility. This
resulted in an unprecedent scenario to evaluate the contribution of the
oil and gas industry (O&G) to methane (CH4) and
nitrogen dioxide (NO2) emissions in the Permian basin
(U.S.), currently the second largest hydrocarbon-bearing area on Earth.
TROPOMI (Tropospheric Monitoring Instrument), on board the Sentinel-5P
satellite, has captured the impact of the oil and gas industry during
the COVID-19 lockdown. Production and drilling declined (13 % and 68 %
respectively) during the lockdown, causing a generalized drop
(~30 %) of NO2emissions derived using
the divergence method in comparison with 2019. NO2
tropospheric columns were less impacted with a smaller decrease
(~4 %) across the basins. On the other hand, the impact
of the lockdown in methane (increase of 0.1 % to 0.3 % across the
basins) was not as evident as in the NO2, because of the large
background cause by the long lifetime (12 years), the variability of the
meteorology, and the limited temporal sampling due to the strict
thresholds of the retrieval algorithm. This study demonstrates that the
impact of the COVID-19 lockdown on NO2 and
CH4emissions was not only present in urban areas but
also in vast O&G production regions, which shows the potential of
TROPOMI to assess future pollution mitigation strategies for this
industry.
