Donald Trump's election as US president brings back a champion of the oil industry to the White House, but experts warn that his push for low prices could be at odds with petroleum companies' priorities.

On the campaign trail, Trump repeatedly said he would "unleash" the US oil sector by boosting production and curbing the move towards renewable energy pushed by outgoing president Joe Biden.

"We will have an administration that will work with the US oil and gas industry and not disparage them by calling them war profiteers or price gougers like they were called by Biden," said Andy Lipow of Lipow Oil Associates.

"I will lower the cost of energy," Trump said at the Republican National Convention. "We will drill, baby, drill."

The president-elect's vow to press for aggressive oil and gas development is, however, something experts say is not the main priority of a sector that has been criticized in the past for not carefully investing capital.

"Producers have plenty of acreage they're sitting on that they could be drilling, and some of it they're drilling, but they're also trying to placate their shareholders," said Stewart Glickman of CFRA Research. "And the shareholders want dividends and buybacks just as much as they want volume growth."

A significant increase in output -- already at record highs -- risks glutting the market depending on how medium-term demand evolves in places like China, where the economic outlook is uncertain.

"The problem is the capital markets," said Bill O'Grady of Confluence Investment Management. "Investors don't want them to do that (raise production) because they want to get paid."

Higher output could add to downward pressure on oil prices at a time when the strong dollar is also expected to weigh on the commodity.

- Pressure to produce -

US oil output began heading significantly higher in the 2010s with the emergence of shale production, but the domestic industry has faced obstacles along the way.

With shale booming, Saudi Arabia opened the spigots enough to send crude prices down to $26 a barrel in 2016.

That tumble in prices reverberated through the oil industry, leading to multiple bankruptcies.

Darren Woods, chief executive of ExxonMobil, said last week that industry investment is more influenced by its drive for profitability than regulatory questions.

"I don't think the level of production in the US is being constrained by external restrictions," Woods said. "I think it is being driven by the internal discipline of the industry."
