<\/p>\nOnshore gas flaring in the US nosedived in the third quarter of 2021, falling to its lowest level since at least 2012, Rystad Energy stated.<\/p>\n
Flaring activity reached 380-390 million cubic feet per day in September, a roughly 24 percent fall from the prior month alone. Flaring activity is tumbling as best practices that only major operators had previously adopted spread to smaller, independent players.<\/p>\n
<\/p>\n
The most significant contributors to this steep decline were the Bakken and Permian plays, which saw reduced flaring of around 50 million cfd each in September. This trend was not unexpected, but the Permian declined rate was more dramatic than anticipated.<\/p>\n
Rystad noted that US flaring data from the early days of the modern shale era was inconclusive, meaning this record could be the lowest flaring activity since the shale boom of the 2000s.<\/p>\n
\u201cWhile the reduction in the Bakken was largely in line with expectations, based on our analysis of satellite data, the rate of change in the Permian is surprising,\u201d Artem Abramov, head of shale research at Rystad Energy, said.<\/p>\n
The decline in flaring activity across the board is a concrete sign that best practices are spreading beyond just large producers to small, privately-owned operators too, and this trend looks likely to continue in the foreseeable future,\u201d he added.<\/p>\n
The contribution of privately-owned players to gas flaring totals has declined from a record high of 61.5 percent in April 2021 and sits at 52.3 percent as of September. However, that rate is significantly greater than the same companies\u2019 contributions to total gas output, which was 24.8 percent in September.<\/p>\n
Rystad stated that declining gas flaring was a trend across the basins. The average flaring intensity across the 50 largest gas producers in the Permian was 1.6 percent in the third quarter of 2021, compared to 2.5 percent in the first half of 2021 and 3.2 percent in 2020.<\/p>\n
The Permian\u2019s wellhead flaring intensity hit a multi-year record low of 0.8 percent on a gas production basis, and 32 cubic feet per barrel on an oil production basis, in September. The basin has demonstrated steady improvements in its flaring intensity since 2019, closely following the reduction in south Texas\u2019 Eagle Ford, with a five-to-six-month lag.<\/p>\n
Eagle Ford operators flared only 0.4 percent of gas in September, but their flaring intensity in the first half of 2021 was also close to the 1 percent mark.<\/p>\n
The Bakken region’s intensity remains significantly higher than basins in Texas and New Mexico. Still, it has come down from an elevated level of 10 percent in July 2021 during the gas plant maintenance season. About 6.1 percent of gross gas was flared in the Bakken as of September, with gas-based flaring intensity levels essentially returning to previous multi-year lows recorded in early 2021.<\/p>\n
However, as gas production in North Dakota substantially outperformed the oil stream in 2021, flaring intensity on an oil production basis in the state was still at around 164 cubic feet per barrel in September, roughly 15 percent higher than the level recorded in January 2021.<\/p>\n
As for the Permian basin, nearly all major operating areas, or sub-basins, experienced multi-year flared gas volume lows in the third quarter. For instance, the low gas-to-oil ratio Delaware East sub-basin had a flaring intensity of 5.7 percent in the third quarter of 2019, the equivalent of 131 million cfd of flared gas in absolute terms.<\/p>\n
In the third quarter of 2021, flaring intensity levels in the sub-basin declined to 1.1 percent \u2013 still marginally higher than the basin-wide average of 1.0 percent \u2013 meaning only 26 million cfd of gas was flared in the sub-basin.<\/p>\n
