$this->bbcode_second_pass_quote('Revi', '
')The amount of oil also declines with depletion, right? This is just as a percentage of the remaining oil.


The first chart is irrespective of when peak occurs and just looks at EROEI and the effect it has on any level of production. Assuming the trend in EROEI continues, or even if gross production plateaus for a little longer, there will be 1:1 situation after 2050 and no matter how much oil is still in the ground then, it will stay there.

Now if you factor in the possibility that peak production occurs in 2010, and the rate of gross production falls at 3.5% per year, then the line added on this chart more or less portrays the fall in net production available to us, the green line. The green line is the percentage of gross production at peak that is produced in the future as a result of depletion, and a result of falling EROEI. It all drops down to 1:1 and then quits. The fact that we go below zero is just an artifact I used to make the graph not abruptly end because it became harder to read if I did not take it out a little farther than the end of oil.

The green line is a combination of failing EROEI and depletion after peak oil; not a very pleasant future.

If you remember that Richard Duncan considered 1930 to 2030 to be the oil age, it now looks his 2030 date is quite reasonable. If peak gross production is 2010 and production cost at a minimum continue on trend, then 2030 have only 34% of whatever 2010 peak gross production is to then use.

I was intrigued by his method of calculating the end timing of a spike in electrical flow, which yielded the date 2030. Independent of that I did some study of market peaks and crashes and placed a similar date in my mind as the likely end of meaningful oil production.

This exploration of EROEI combined with depletion rates post peak certainly makes 2030 a reasonable time to look for the end of meaningful oil production. The hope that there will be a substitute for light sweet oil that will overcome the diminishing return effect is in my opinion more a wishful dream that reasonable, simply on the EROEI issue alone, because all known substitutes are just a continuation of the progression to 1:1 EROEI.

What would 10 of 20 years one way or another mean anyhow?

A few years ago, on another, energy-unrelated forum, we got to talking about oil, and one of the posters said the world would be completely out of it by 2030.

Everybody made fun of him.

I think we need to move on a bit. It's a nice chart but I think we all know what Gazza was trying to say.

We try to hide behind the future sometimes - the same way we do with the past. But at some point soon, we will all throw these charts, and our hopes, and fears, in the bin and just get on with our lives (with or without EROEI).



I was not part of the "we" that fully appreciated what Gazza was saying, so, if anything I am posting my thoughts as an exercise to improve my own understanding and to bring this vague concept into slightly better focus for myself. Just ignore me if you find me concentration on the topic tiring.

I do appreciate your reminder to stay in the present, as I do sometime wander off.

So I think I am about done on this topic, anyway.

Assuming that this graph is correct (no insult intended), that is one scary looking green line. The slope is very dramatic and it looks like the next 25yrs are going to be one hell of a ride (where's the eject button?). It's not just the fact that we will be having less and less oil, but the slope will not allow the majority of the population to adjust and adapt. If the slope was more gradual, then it would be painful but I think people might make the necessary adjustments. As it stands, this is going to come as a shock to the majority of the earth's population.

In my opinion, even though the amount of oil will continue to decrease after 2030 and life will be even more challenging, those who make through the next 25 years will have a better chance at survival (darwin + less of a social/emotional/psychological shock to the system).

Now where is that cave again -- need to hibernate for the next 25yrs. Best ER

Sorry, but no warranty comes with my machinations.

The possible flaws: The EROEI (halving every 20 years since 1930) numbers provided by others may be inaccurate; the EROEI rate of decline may not continue at 3.5% (could be worse or better, but a trend in motion should not be ignored); the 2010 peak oil date is an assumption and could be earlier or later; the rate of decline in production after 2010 could be different than the 3.5% assumed (I have read estimates of 8% also).

I am comfortable that I did the math correctly in converting the EROEI ratios (the blue line) to % of net oil available out of gross production (the red line) for each of the declining ratios. The little list of ratios and corresponding % is on page 3 of this thread. You can check this out yourself by some fairly simple calculations. For example, the table shows at an EROEI of 3.125 a net 68%. On 1,000,000 barrels 68% is 680,000 remaining. That means 320,000 barrels were used in acquiring the 1,000,000 barrels. Since the EROEI is 3.125:1 multiply 3.125 X 320,000 = 1,000,000 barrels, proof that the 68% is the correct % for a 3.125:1 EROEI.

For the green line; If the decline rate is 3.5%, this means production falls by 50% every 20 years so the progression of lost production is 100%, 50%, 25%, 12.5% etc. I took the table of %'s on page 3 of this thread and multiplied by this progression; 100% X 84% for 2010 (since 2010 is the assumed peak production date), 50% X 68% for 2030, and 25% X 36% for 2050. This may seem a little contorted, but I did it that way to get it on the graph by keeping everything in percentages. The red line is what would remain out of any theoretical production level after cost of producing. Since we assume that 2010 is peak production, we can then use this as a reference point, hence the green line becomes the % of 2010 gross production that is left at each future date taking into account declining gross production and increasing production cost (falling EROEI). I may be having difficulty explaining the logic, but I do think it is sound. One thing that bolsters my confidence is that the three lines on the graph meet at 1:1 EROEI in 2060.

I tested using different rates of decline in gross production and the slope of the green line changes, but it always meets the red line where EROEI falls to 1:1.

If you are shocked by the slope of the green line as I presented it, consider what it would look like using a depletion rate of 7% instead of 3.5% for post peak production. Instead of falling to 34% for 2030, the line falls to 17% at that date, but is still reaches zero at 2060, so it flattens later. No matter what rate of depletion you assume post peak, you always will arrive at the destination of zero, controlled by EROEI. If you assume gross production stays constant after 2010 the green line matches the red line, if you assume production increases after 2010 the green line is higher than the red line, but it still falls to meet it in 2060; all roads lead to Rome.

This is why Gazzatrone's thread is so important; the issue is not peak oil; it is falling EROEI. The only thing peak oil means is how fast we get to hell; whether we go directly there by 2030 at anywhere around 3.5% or above depletion rate post peak, or we play in the sandbox for a decade or so more before we drop off a relatively higher cliff to go to zero in 2060.

The discussion might better come from oil insiders who have a better understanding of the present and future overall cost structure of oil production, because the better we understand EROEI, the better we can predict our future.

Great work above and great thread.

On the front page of the NY Times today (also in the PO news section), we learn that the marginal cost of oil secured by the US government under some GOM royalty programs is $80. Outside of a brief moment when oil actually hit $80, the US is engaged in an activity with a negative payoff. It's possible that the EROEI is also negative.

After seeing the article earlier this week that the much proclaimed “Jack” deep water discovery in the GOM was going to be plugged up for many months before more drilling occurs, one gets the impression that major oil companies are also pushing the limits of EROEI within the US.

If these trends we see here in the US can be projected to the rest of the world, we will indeed see continuing – and possibly accelerating - drops in EROEI before too long, if not already.

To illustrate how the controlling factor is EROEI, not peak oil, I did two more charts.
The first assumes instead of a 2010 peak oil date, a date of 2030, everything else being the same as the prior chart:
Image
The second assumes a peak oil date of 2010, but instead of a 3.5% depletion rate thereafter, it assumes a 7% depletion rate.
Image
Compare this to the previous chart. This is not to say that the peak oil date and subsequent depletion rate are not important factors very near term, but it does not change the big picture.

Unless there is some magical "get out of jail free" card that can be played to alter the EROEI trend in oil production or to substitute completely for oil (including drilled oil, grown oil, converted from coal oil) then it looks to me like tough sailing ahead. If you hold this card, please come forward now.

I did not mean to make light of individual circumstances. I was more thinking in broad terms of the entirety of the oil age.

None of us will have an easy time, if this develops over the coming decades as I am prone to believe. But then just remember that you have some foreknowledge that gives you an advantage. Just stand by the lifeboats rather than party in the grand ballroom, so to speak.

Is "retirement" some safe haven? Would you rather make it to "retirement" and then start to see increasingly dire effects of PO, rather than start to see those effects sooner? (Assuming no miracle occurrs, of course).

Indeed I do gego, and thank you especially for keeping it alive so well. If it not for my family tragedy, I'm sure I would have contributed as equally.

Excellent charts by the way. There's nothing like a few pictures to spell it out. As most will have gathered from my style of posting, that I try to base my analysis with a Humanitarian (if that's the word) point of view, and not a scientific one. Recent events have made me question myself, bringing into stark realisation that we are not in control of our destiny, but hopefully can affect others. In some way I hope this thread has done that. For that reason alone I hope this thread continues as it keeps the threat of EROEI in focus.

And on a personal note, from reading other peoples comments about the thread, I know my sister would be proud of what her big brother has started.

Retirement is a goal, a kind of nirvana. I know that it's probably just wishful thinking, and that things aren't going to be any better then, but it's something to look forwards to. If I think too much about what's really coming I get too bummed out. One day at a time. The reality of peak oil is too dark to use as a way to make it through the years. Better to make plans, switch to renewables, look on the positive side. You never know what will happen.

They say that in survival situations you should never give up hope. Not delusional hope, but a certain faith that things will work out okay. Whatever happens, I try to have a little hope. We have switched things around in our household/lifestyle, and I hope it will make a difference. We could have the electricity go out, get around with no gasoline, heat the house and the hot water. The only thing we'd have to pay would be the water bill, and the taxes I suppose. Here's what we've done:

Revi,

What you have done is very good for temporary problems related to energy; quite admirable from some, even most perspectives.

What I do when I am trying to understand something is to imagine a super extreme case. Don't think in terms of the power lines falling down do to ice, to be fixed in a few days or even weeks. Think of no more electricity at all, never ever, and what you would do. Maybe the extreme will not happen, but it gives you the range of possibilities as compared to today.

Oh, I forgot to mention, retirement is not a pass to Disneyworld. It is just an opportunity to work harder to make it possible for you to live until exhaustion.

Gego, all the stuff we have done will work even if electricity never gets turned back on. The sun will heat the water, the wood will go in the stove, and I'll keep finding batteries in dead SUV's to keep the LED lights on in the house. We even have a solar car in the works to get around in. Check out the movie we made on it:

You've done a lot of good stuff, Revi. I'm planning on building a new energy efficient home with many of the things you've done built-in. But I'm just at the beginning of that process, so I'm hoping "normality" lasts another year at least.

But I've completely discounted retirement, now. I'm about 10-15 years away from the normal retirement age but I don't expect to retire, though I may stop doing normal work very soon. I'm glad I saved some money in a pension scheme because I can use that money now to help finance a new more sustainable lifestyle.

Nirvana is, as you say, wishful thinking.

I would have to agree with you on that. But retirement is a choice that we can decide to make. I know many of my parents generation have retired early purely because the oppurtunities given to them have allowed them to, even my parents took semi-retirement a year ago. Downsizing after the kids have gone, clearing their mortgages with a hefty bonus to boot after selling the larger family home, makes for an easier life. For them retirement is a natural progression, where an economic environment has been on their side.

This will be the last and only generation to enjoy the freedom to choose to retire. One of the consequences of living in a World fully dependent on a finite resource is that when it goes and I would suggest long before it goes, many will take "retirement". Not by choice but by the fact that their profession or job sector will no longer be able to sustain itself and disappear.

I think you are right, Gazzatrone. We may be "retired" sooner than we think. What do we do then? I think that will be the chance to radically downsize our lives. We'll just have to mellow out. We won't have enough money to run around. I think I'll cut some wood, make some woodblock prints, plant a garden and tend it. It won't be so bad. It won't be so great either.

We are living in some interesting times. Since we can't change the overall situation, we'll just have to deal with our own personal way of living. We may be able to get through this. Maybe...
