Observed decline rate of the 1,600 fields that provide 70% of the world’s oil today and that are post-‐peak, you have an observed decline rate of 6.2%.
More broad view. If you look all of the fields currently producing conventional crude oil today, they produce about 69 million barrels of oil and that with ongoing investment in those fields over time that is natural, you would get to 28 million barrels by 2035.
If you look at the raw numbers, global upstream capex for the oil and gas industry - and about 75% of the total is just for oil -‐ has trebled in real terms since 2000. The IEA estimates that upstream capex this year will be about $700 billion compared with $250 billion in 2000 in real terms. Those numbers are in constant dollars. So that is a real term increase of nearly three times.
US, of course, is most efficient, as mass media will tell you.
OECD in North America is producing about 20% of the world’s oil at the moment but OECD in North America accounts for 50% of the world’s capex for oil.
Sorry, they again lied to you. Some independent estimates show that for each $1 invested US gets shale oil worth 10 cents.

Small illustration in example of UK to show that US is not alone:
As you can see big investments can't even hold declines.

After nearly 50 years of production, Britain’s oil sector has reached a crucial point. To put it bluntly, Britain’s offshore oil industry has entered old age. The size of discoveries has tailed off sharply, a classic sign of maturity. Production has fallen 37 percent from 2010 levels, while costs, thanks in part to the need to maintain creaky infrastructure, have soared. All of this adds up to sharply reduced profitability of the oil and gas fields, to a point where some of them lose money. Executives say that unless the British government and energy companies adjust to the new realities, the industry could find itself in deep trouble.
