Let me repeat it again. As a percentage of the price, the light /heavy spread is not higher than it used to be!
I'm not convinced that light sweet oil is running out quicker than heavy sour (unless we count oil sands/tar as heavy sour).

Do you have any documentation of this?

I'm not disagreeing. However, this is contrary to conventional wisdom and the basic point is very important.

Claims that light oil has peaked and that refining capacity, particularly complex, is constrained would both lead to an increased spread. In the past, I have charted spreads fro EIA data and noted the increase, however I have not adjusted for price.

Spreads can be viewed as being created by refining configurations. If the spreads have not grown, it brings much of what is said about current refining into doubt.

I may try to chart this later, but won't have time for a few hours and don't have a website to post it on.

I think he's basing it on the fact that the spread has roughly doubled or tripled over the historical average as per Jubak's article, while during the same time frame the price of oil has roughly doubled or tripled.

You can post anything you want on my site. I'll even post it for you here. Send me images or Excel spreadsheets. theoilceo@yahoo.com

Thanks for the website offer. I'll probably take you up on it one of these days.

I think you are right about the spread question. Since refinery configurations determine spread, I suppose an absolute figure could be viewed as more relevant than a relative figure.

By this I mean, if the refining industry expends an average of $5 more to refine a heavy crude, it should cost about $5 less. So a $15 dollar spread is telling us something, even though in terms of the base price it is unchanged.

I do think this is worth exploring as it is another useful clue to what is going on out there.

Thanks for the Jubak link. Not sure the guy should put his photo up there though.

I have nothing to do with spread question. In fact I know very little about the spread issue. Any credit is due smekhovo. I was only trying to debunk him, when I realized he might have a point.

Jubak's great. I'm glad Dave finally got turned on to him. Very smart guy and totally "with it" on energy issues. He follows the money. I can only hope he pays attention to environmental and moral issues with the same tenacity.

As far as his photo...what, you don't like large mustaches? I guess only AlphaMaleProphetOfDoom and his girlies would be impressed.

Evidence of my view is that the spread between light sweet crude and, for example, Urals - which is significantly heavier and sourer than Brent or WTI, but less so than Maya - is actually much less than it used to be as a percentage of price.

OK. You are probably right. I'm still going to track down the data. I found a great spreadsheet of crude price hiistories at EIA one day, but can't locate it now. Should get it done tonight.

However, after further reflection, I think it is the absolute spread ($ terms)that matters, not the relative spread (% of crude price).

Spreads between crudes are basically determined by the cost differential between converting heavy crudes and light crudes to products. As I noted above, if the average cost of converting a Urals slate to a given product slate is $5 more than the cost of converting WTI, the spread should be about $5.

If the spread has gone up in proportion to the oil price, I do think it represents a lack of light crudes and/or complex refineries. Absent these constraints, I think the spread would have remained consistent in nominal terms and shrunk in relative terms.

Valero's refining margin is basically fixed. They, like other highly complex refineries, make money when the spread is large in absolute terms. The crude price itself and the value of the spread realtive to it are not important.

The fundamental spread tht determines profiablility is the price differential between cost per barrel of heavy sour crude and the price they get for the products produced from that barrel of oil.  

Part of the reason for the discount for heavy sour crude is because it doesn't produce as much gasoline.  If that is the dominant reason for the spread then it makes good sense that the spread betweeen heavy and light should remain constant on a percentage basis.  

If on the other hand the spread is really there to compensate the refiner for the added cost of refining the stuff then it should remain constant on an absolute basis.  

In the real world it would be a mixture of the two, it is probably best just to attempt to track the spread between their cost of materials(heavy crude) and the weighted average of the price they get for the products.

I am not an expert in refining, but I do know that crude is sweetened at a refinery by mixing it with hydrogen with a catalist and taking the resulting hydrogen sulfide gas and removing the sulfur by freezing it so the sulfur drops out, or burning the hydrogen sulfide. All of this process is energy intensive-the hydrogen comes from natural gas. Gas prices are fairly low right now, but, as they rise will raise the refining costs. I haven't the slightest idea about how much gas is needed, but probably someone who knows can fill us in.

This being the case you would think the gas going forward will cause exponential price increases at the pump as we pay twice to make gas from crude?  Would this be fair?
