At a half million barrels per day, it would still take a year to replace it.
Put that in perspective. that's the capacity of the Dakota Access Pipeline which transfers half (roughly) of North Dakota's production to market.
The US uses roughly 18 million barrels of oil per day and the difference would have to be made up either through additional imports or increased production. Biden has waged war on the domestic oil industry, effectively locking drillers out of some prime areas, so don't look for any off the charts new production from the oil companies here. They are drilling what they can, but that is limited, as are the options for getting it to market (another Biden artifact).
Siphoning off that much oil from supplies will inevitably make the price go up, so if he thinks the SPR is going to get filled cheaply, he is just plain wrong. Forcibly decreasing the market for Natural Gas by attacking the consumer end won't help, either, because that gas is a byproduct of oil production and can't just be flared (environmental rules), so the only way to limit it is to use it as a fuel or just not produce oil. If less gas is produced, less oil will be, too, and that will further exacerbate price increases for oil.
In short, that can will be kicked down the road until we get some adults in power who can reverse the regulatory damage and clear the way so we can build/expand pipeline and refining infrastructure.
