Among 54 publicly traded crude oil producing companies, natural gas revenue accounted for 14% of total revenue in the first-quarter 2021. That percentage is the highest share among these oil-producing companies since at least 2018. The share of revenue associated with natural gas among these companies decreased to 10% during the second quarter of 2021, but it could remain relatively high as natural gas prices continue to increase.

During the first half of 2021, production outages after a February cold snap in Texas and increasing international demand for liquefied natural gas caused the U.S. natural gas benchmark spot price, Henry Hub, to briefly triple in price. The price remained at more than $5 per million British thermal units (MMBtu) for more than a week during February 2021. Natural gas prices have been trading at or above $5/MMBtu since mid-September as well.

Financial earnings from the first half of 2021 show that these 54 U.S. oil producers have reported both higher revenue and increased cash flow from operating activities (also known as operating cash flow). These companies have not yet invested the additional cash flow into capital expenditures in line with the additional revenue. Because of that, the companies are reporting higher free cash flow, which subtracts capital expenditure from operating cash flow. With positive free cash flow, producers can pay for capital investment programs or use it for other financing activities, including debt reduction, dividend increases, or share repurchases.

Through the first half of 2021, these companies had not significantly increased oil production. Instead, they were drilling fewer wells and relying on their inventory of drilled but uncompleted wells to complete new wells at reduced costs.

The list of publicly traded oil-producing companies does not include large oil companies with refineries (also known as oil majors) or companies that produce natural gas as their primary business, so these trends cannot be considered as reflecting behavior in the industry as a whole.
