Facts and Myths About Offshore Oil

Can We Drill Our Way To Energy Independence?

By Chris Nelder
Wednesday, April 29th, 2009

A new battle is brewing over offshore oil drilling. Nine months ago, President Bush lifted a ban on new oil and gas leases off the nation's coastlines, and the congressional moratorium on offshore leasing expired last September.

Now Obama's Department of Interior officials are considering reopening the Outer Continental Shelf (OCS) to leasing, and once again the oil industry is pitted against environmentalists, as well as California residents who remember the ugly mess that a 200,000 gallon crude spill made of the Santa Barbara coast in 1969 after an offshore rig blowout.

I remember that mess. Some time in the mid-70s, when I was 10 years old or so, my family took a trip to California to visit relatives. After nine long hours in the car from our home in the Arizona desert, I wanted nothing except to frolic on the beach when we finally got there, and I wasn't about to let my uncle talk me out of going there no matter how bad it was.

It was nasty. The beach was covered in globs of black goo—so much of it you couldn't avoid stepping in it—and the whole place reeked. (If you haven't ever smelled crude oil, it's smells like exactly what it is: a combination of asphalt and gasoline and everything in between.) We had our fun on the beach, but when we got home, we had to endure a good scrubbing down with turpentine (or maybe it was gasoline) to get the gunk off of our skin.

So I have sympathy for those who don't want to see that sort of thing happen ever again. I've also been an environmentalist all my life.

On the other hand, I believe our energy predicament is shaping up to be so dire as to render all such ideology moot. Taking a principled stance on environmental grounds may soon seem like a luxury of a far-gone age.

Outer Continental Shelf Potential

Let's take a look at the numbers.

According to the EIA (2007 data rounded to billions), total US proven reserves of conventional oil are about 21 billion barrels, of which 4 billion are proved offshore reserves.

US demand is currently about 6.7 billion barrels per year, so if we relied solely upon our proven reserves and were able to produce it as quickly as we like, we'd only have about a three-year supply. Fortunately, we are able to import more than two-thirds of our oil consumption from elsewhere. Nature limits the rate at which we can pump our domestic oil, a rate which has been in steady decline since US domestic oil production peaked in 1970.

Three years' worth isn't much, so we have turned to the difficult and expensive stuff that remains, some of which isn't even oil: low-grade tar sands from Canada, thin seams of shale in the Midwest, and the OCS.

Energy and Capital readers are no doubt familiar with our articles on tar sands and the shales (Bakken, Barnett, Marcellus, and others), but an update on the OCS is probably in order.

The EIA estimates that "technically recoverable undiscovered" offshore oil in the US is in the range of 59 billion barrels—nearly three times as much as our remaining "proved reserves." Most of it, about 45 billion barrels, is expected to lie in the Gulf of Mexico.

The remaining 31% is what was unavailable under the Congressional moratorium, but according to a testimony before the House last month by acting EIA administrator Dr. Howard Gruenspecht, only about 20% of the total technically recoverable oil in the OCS has been under moratoria.

The United States Geological Survey (USGS) numbers are considerably larger, suggesting that some 85 billion barrels of technically recoverable undiscovered oil may remain offshore. (For the present article, I will avoid delving into the murky details of probabilistic reserve estimates and why they differ from source to source.)

In any case, it's clear that the remaining oil prize in the US is offshore. So why aren't we producing it?

Partisans like Sen. Kay Bailey Hutchison (R-TX) would have us believe that it is simply the politics of overzealous environmentalism, banging the drum loudly for offshore drilling and complaining that 85% of the OCS has been off-limits "leaving some of our greatest energy reserves untapped." Indeed, the "Drill Baby Drill" crowd claims that if only we'd drill the OCS everywhere, we could achieve "energy independence."

But if only 20-31% of the OCS has been off-limits, why hasn't the rest been drilled yet?

Risky Business

One part of the answer is that there simply isn't any oil in some of those areas. Last July, John Hoffmeister, former CEO and president of Shell Oil's US operations, told CNBC "The industry is pursuing the leases it has, but to be blunt, the prospective nature of many of those leases is very low. And you don't go drill oil where you know it doesn't exist."

The second part of the answer is also simple: poor economics.

Offshore oil is expensive, and deepwater oil—wells drilled in more than 1000 feet of water—is more expensive still. Leasing rates for high specification drillships able to produce oil from deepwater formations have run as high as $600,000 per day, which is why we have liked our deepwater drilling players for a long time now.

Consider the economics of the Mars field as an example. At a water depth of 2,940 feet, it is believed to contain 500 million barrels of oil equivalent. The platform produces some 220,000 barrels per day, at a reported development cost of $100 million. Prior to the development of BPs Thunder Horse platform, it was the most advanced platform in the deepwater Gulf of Mexico, where the best prospects for new US oil production are. The Mars platform was destroyed by Hurricane Katrina, and rebuilt by Shell at a reported cost of $200 million. (By comparison, the Thunder Horse platform produces oil at about the same rate, but has a total cost of around $5 billion.)

Deepwater oil also remains a very risky enterprise, even with modern seismic imaging technology. This week Contango Oil & Gas Co. (AMEX: MCF) reported that it would take a $12.5 million write-off for drilling a dry hole in the Gulf of Mexico. It takes a fluid and committed credit market to sustain that kind of risk, but the world is still in the grips of a credit market freeze.

Morgan Stanley recently reported that enough deepwater projects have been scrapped in the global economic downturn to reduce future crude supplies by as much as 2.4 million barrels per day (mbpd) by 2011, a substantial chunk of anticipated supply. Since August 2008, the company reported that no new lease contracts had been awarded, but 11 orders were canceled and 46 more were delayed.

Perhaps the largest project to be delayed recently is the Manifa project in Saudi Arabia. With a $9 billion price tag and a possible 900,000 barrel per day flow rate, it would be the country's largest offshore oil development, but progress has been delayed by six months, probably to take advantage of lower construction costs.

How Do We Reach Energy Independence?

Finally, we must also address the flow rate of any new domestic oil. True "energy independence" would mean producing 18 to 20 mbpd, not the roughly 5.5 mbpd we are producing today. Could we do that?

Through drilling alone, the answer is "not even close." In total, I estimate that if all limits on drilling were removed, including the OCS and ANWR, we could only increase US oil production by a maximum of 2-3 mbpd. That new production would come online slowly, and the additional flow would be hardly noticeable as it compensated for the loss in conventional oil production due to sheer depletion. If it lowered prices at all, it would be by a few pennies per gallon, at best.

Now I have no doubt that Sen. Hutchison understands this, but within the parameters of politics, she must state her case as strongly as possible and try to overcome the resistance to offshore drilling.

Nor do I have any doubt that the hearts of anti-drilling environmentalists are in the right place. Why continue down the doomed path of oil dependency when renewables appear to be right around the corner? Why would the good people of Florida want to court the disaster of oil spills, or look at oil rigs in the distance of their beautiful beaches?

Both sides of the issue, unfortunately, are wrong-headed, and would lead to poor policy. If the public were successfully convinced that we could drill our way out of our energy dilemma, it would stifle development of a renewable-powered infrastructure that will survive in a future of declining oil. Conversely, large oil spills from offshore drilling are a thing of the past, and if we do not drill our remaining reserves with all possible haste we will undoubtedly find ourselves without sufficient oil at an acceptable price within just a few years.

The IEA's warning in February should remain foremost in our minds: If oil demand recovers in 2010, global spare capacity would fall to zero by 2013. And as the world's largest nation dependent on imported oil, we could be in for a very difficult time. The last thing we should do is pull the plug on the majority of our energy supply, which is oil, before we have new forms of energy to replace it. To do so would have terrible consequences on the economy, and hamstring our capability to continue evolving to a new energy regime.

Our only real path to energy independence is to pursue all options, within acceptable emissions limits, and gradually phase out fossil fuels as we ramp up renewables and the electric infrastructure to support them. But while renewables remain less than two percent of our energy mix, we should be careful not to expect too much of them. We will need oil and natural gas for decades to come, and in time we will need to develop our offshore resources or face the prospect of shortages.

Until next time,

Anyone who does not understand we are running out of oil and we have only one or two viable alternatives is either self delusionsal or plain stupid.

The immediate fix is natural gas.

However long term it is coal. Yes we have many problems with coal. But why not use what remaining time we have left figuring out how to use it cleanly. Why haven't the geniuses in Washington figured out we need a Manhattan project for coal?

And let us not forget those curious missing equations from the emasculated four equations of Maxwell.

The Mars platform based on your math should pay off in 34 DAYS not 34 years.
Comment by Joe Stephens on 2009-04-29
It's nice to see an even handed article on this subject. I agree with most of what you say. I think that we must develop all energy sources: oil, natural gas, alternatives, and nuclear. I believe that if you ask most any conservative, that is the position they will stake out. The belief that conservatives believe only in drilling and to Hades with all other sources is a well parroted caricature and a political myth designed to marginalize them politically. "All of the above" development is the way to reduction of our foreign energy dependence. The environmentalist anti-drilling folks are the ones with their heads in the sand. We will never get to a sustainable energy program without a gas-oil-nuclear bridge to get us there.

I appreciate your articles regarding oil exploration. As an owner of mineral rights (with signed leases) on land in Mercer County N.D. I wonder why they don't go ahead and drill there where there aren't all the emotional issues of off-shore drilling. I understand that oil must be around $ 60 to make it worth while, but every barrel produced domestically is one less that we have to import from the Middle East. Let's get the wells in place NOW!!
Comment by Mike Jonas on 2009-04-29
Excellent article, thanks.

As I have said a few times before, though, you don't need to worry about CO2 emissions. The whole AGW "science" is on the verge of collapse, with scientists leaving the sinking ship in increasing numbers, because the Earth's climate is simply refusing to follow the IPCC script.

The trigger, though, looks like being the economic downturn - people will reject the additional economic burden of an ETS.

"Assuming those numbers are still correct, at a $300 million total cost the project would take 34 years to pay for itself at $40 a barrel. "

If your numbers are right that's 34 DAYS.

Good middle of the road thinking. Energy requirements going forward, after we get thru the current mess in a year or two, is going to increase dramatically. We will need multiple sourced alternatives to meet that demand. Hydrocarbon sourcing will not be sufficient in and of itself within 10 years at the outside. I believe electical requirements will be met, the big moose on the table is transportation energy, ie moving people and goods of all types around the world. Transportation efficiency and reliability have become the biggest determinant as to who will have the most dominant economies in the near future. The US has leveraged the best transportation system in world into economic dominance over the last 80 years, since the end of WW1. That may be about to change.

Chris,
I'm the guy who pointed out to you that personal and corporate tax revenues increased after the Bush tax cuts...never did hear back from you...even after I sent you a very thorough analysis backing up my facts.
On this article, I want to point out that not too long ago the Santa Barbara county panel voted to push the state to open it's offshore for more drilling. It turns out new sub industries were spawned from that spill, and the industry went through a transformation on how they drill and handle pressures in the process.
No one wants to see another spill. No one. But this isn't the decade of flower children or hippies. Take a closer look.
Comment by Tony on 2009-04-29
Chris, I don't think you have a clear understanding of many of the issues.

First of all, I live in Santa Barbara. An amount of oil equal to the Exxon Valdez spills here every three years- FROM NATURAL OIL SEEPS. The largest source of air pollution in Santa Barbara? Natural oil and gas seeps. If you travel offshore here in a boat, there are places where the sea appears to be boiling, from natural gas seeping to the surface from natural seeps. There are on any day oil slicks covering as much as a square mile or more. All of this is natural, not from drilling. The same thing happens in the Gulf of Mexico, although the Gulf's natural seeps are not as prolific as those here in California.

Drilling offshore California has actually made the beaches cleaner in the 30 years I have lived here. The environmentalists that are blocking offshore oil mostly don't know what they are talking about and simply refuse to examine reality. By the way, in 2007 Exxon drilled a well here in Santa Barbara with a 5 MILE long horizontal well bore. The well produced over 1 million barrels in its first year of production. That is simple proof that wells can be drilled from onshore to much of the California offshore oil, and proof that it is really there. The seismic was shot many years ago, so it has been known for many years.

You too seem to be falling for the false logic of "if we can't produce 18 million barrels we shouldn't bother drilling." You will never get to 18 million without first drilling for the first 100,000 barrels. You seem to be forgetting too that every million barrels of oil we import represents a large part of our balance of trade, and as our trade deficit grows, we lose more and more wealth, and the dollar gets weaker. The idea that alternative energy is just around the corner, that can replace 18 million barrels of oil per day is ludicrous. Most alternative energy doesn't even replace oil, and many uses for oil are in products we use every day (about 17% of oil consumption), not energy. How can a solar panel or windmill be used to make shampoo, detergent, aspirin, roof coverings, plastic, carpet, or fertilizer for corn?

You are correct that we will eventually need the offshore oil. Eventually may be next year.
Comment by Paul Hoffman on 2009-04-30
Excellent article, Chris, although your concluding paragraph is disturbingly optimistic.
By your numbers, we can see that if any but a small portion of the future "mix" is Oil, our grandchildren will have to rely on the paltry extractions from olive trees and other vegetation, and there will be virtually none of it for them to run their autos or electrical power plants.
If Pickens is correct, we may have 40-60 years, but that, too, is a time too short for saving the planet.
Won't you agree that our efforts on renewables, while much greater this year, may still fail us all. We can have faith that science and faith will rescue us, but this is not at all assured. Without energy to satisfy the needs to which we've become accustomed, two stark choices await us: 1) energy rationed among nations, perhaps apportioned according to their populations, or 2) energy for the few of us who can afford it. Clearly, the first of these returns us to the state of the rather primitive pre-industrial world, and the second of these will surely be the harbingers of world-wide revolution within and between countries.
It seems clear that any rational consideration of these problems leads to the need for an immediate global effort in science and technology, perhaps by ten-fold over present priorities. Even were a solution to be found, say in 10 years, the hydrocarbons required to put in place the new technology at the scale needed might itself consume the remaining oil reserves on the planet, let alone the continental shelf.
Comment by John Cardwell on 2009-04-30
Yes, for the present, we should do both renewable and nonrenewable. But the problem is that nonrenable resources are CURRENTLY less expensive.
Had we continued to develope nonrenewable sources since the 1970's, we would probably be free of our dependence on forein oil today. 30 years from today our children will be wondering how we got in this situation.
Nuclear and coal (for as long as it lasts) can provide our electricty and power our merchant fleet. Our transportation needs can be easily met by all manner of renewable resources.
HOWEVER, the switch to renewable will cost money. BUT, whatever it cost today, it will cost more later.
Remember, it was only about 100 years ago that the first oil well was drilled and oil was jumping out of the ground in many U.S. states.
Comment by Wes on 2009-05-03
Not only is deep oil expensive but the advanced off shore equipment needed to retrieve this supply, is hard to come by.

But as oil continues back to 100 dollars a barrel and/or we make a decision not to import from countries that do not have our best interests at heart this supply will yield a vast "ocean" of oil.

The market does work, if allowed to operate. Peak Theory fails again.

Comment by Robert Chamberlain on 2010-05-13
What is the percent of oil drilled in US waters that reach US market? I thought most of this oil ended up on the world market and does not actually serve our desire for independence. Should this be considered in development of our engery policy?
