When Will the Giant Oil Fields Fall?

Posted by Wealth Wire - Thursday, June 30th, 2011

Unfortunately, U.S. sentiment toward domestic oil production is a case of foggy optimism.

Look at the facts: U.S. production peaked at just slightly over 10 million barrels per day in November 1970. Domestic production that year averaged approximately 9.6 million barrels per day. That's it.

There's no getting around it. To think we'll ever return to our glory days is nonsense. It won't happen.

Yet despite this decline, we still see rampant optimism.

Let's take a moment today to really examine this kind of wishful thinking...

In March, U.S. crude oil production was about 5.6 million barrels per day. That's a 2.3% increase over the same period in 2010.

Let's put this recent production increase into perspective:

peak oil production 6-29

See that tiny up-tick at the tail end of the chart?

That's the best news we've had in four decades, and it's merely a dent in the big picture. Meanwhile, consumption is once again north of 19 million barrels per day.

Now, we're not trying to detract from the good news. The rise in unconventional production over the last few years is the reason there's any optimism at all. But unfortunately, it's also giving us a false sense of security — a muddled cushion that allows us to continue believing all is well with our oil supply.

All is not well. And things get even worse when you look at the bigger decline picture.

The Fall of the Super Giants

Erase any doubt you might have regarding the importance giant oil fields play in global production.

To be considered a "giant", the field is believed to have 500 million barrels of ultimately recoverable oil or gas equivalent. Only a handful of those fields — the top 20, in fact — account for roughly 25% of global oil production.

Also consider that nearly all of these fields have passed their peak and are now in decline, with an annual decline rate of approximately 6.7%.

In certain OPEC members, the loss of production from these giant oil fields could be catastrophic. More than 90% of Saudi Arabia's production comes from just 6-7 fields. The largest of the bunch is Ghawar, at which Saudi Aramco is forced to inject ever-increasing amounts of seawater just to keep the field's production on life-support.

This problem isn't unique to the Saudis. The same can be said of the top oil-producing countries in the world.

In Iraq and Kuwait, nearly all of production stems from just a handful of giant oil fields.

So we can't help but wonder how long the charade will last. After all, the world's giant oil fields have been in production for at least 40 or more years.

You might be saying to yourself, "Not a problem — we'll just go out and find more of these blockbuster oil fields and the problem is solved, isn't it?"

That's not exactly the case. The giant oil discoveries of today aren't just harder to find; they're also much more expensive to produce.

Shifting Production

So here's the rub: Giant oil fields are becoming scarce.

Even though these fields provide about 60% of global crude production, we're simply not finding any more of them.

oil discoveries peakFurthermore, the ones we do manage to find aren't the same as the Ghawars and Burgans, relics of better oil discovery days.

Allow me to give you an example: the highly-touted Tupi oil field.

When it was announced, the U.S. was busy licking its chops in anticipation, and Brazil couldn't wait to fill its coffers. Located in the Santos Basin off the coast of Rio De Janeiro, the 5-8 billion barrels of recoverable oil were as good as it gets in today's Peak Oil climate.

We're constantly told the Tupi field is the largest oil discovery on this side of the world in the last three decades. But what we also have to realize is that some of this oil is buried beneath almost 7,000 feet of water — then an additional 16,000 feet of rock and salt.

Soon, the super giant fields that we depend on will come to follow the Cantarell path...

Cantarell was once one of the three largest oil-producing fields in the world. Following its peak production in 2000 at 2.1 million barrels per day and subsequent steep decline, the field isn't even the largest in Mexico, having taken a backseat to the Ku-Maloob-Zaap complex.

Peak Oil Investments

The good news is in all of this is we have a road map to show us where production is headed.

Roughly half of global oil production comes from about 4,000 smaller fields. During the next few decades, that gap will continue to widen — especially once the giants start failing us. And there's already a fight for that future supply...

In Canada, a war is brewing over who will receive crude oil from Alberta's oil sands resource.

While the United States continues to fight over the proposed Keystone XL pipeline (a decision on the pipeline is expected later this year), which will ship up to 900,000 barrels of oil sands production to U.S. refineries, the Canadian oil sands is becoming more attractive to Asian markets.

In 2010, oil sands deals from Asia tripled — mostly from China, Japan, Thailand, and South Korea. In total, nearly $10 billion was spent last year by Asian energy companies, an 85% increase over 2009.

Some of the investment opportunities in the oil sands are simply too good to overlook.

We're coming up on potential shift to in-situ production, a method that will allow Canadian producers to reach up to 80% of the bitumen too deep to be mined.

Until next time,
