The first related to some discussion on the relative production of Saudi Arabia, among others, and the fact that, with Haradh, they had just added 300,000 bd to their capability. The point that has been made here before, is that the Saudi wells are currently seeing about 8% depletion from existing structures, on average. We have referenced the relevant Aramco quotes on this before, but it has just popped up again.
"Saudi Aramco's mature crude oil fields are expected to decline at a gross average rate of 8%/year without additional maintenance and drilling," a Saudi Aramco spokesman said Tuesday.The Aramco intent is to carry out a sufficiently aggressive drilling program so that
But Saudi Aramco has taken a number of measures to offset a decline in output from the country's aging oil fields, the spokesman added. "A variety of remedial activities are always being taken in oil fields influencing their effective decline rates," the spokesman said. "The drilling of additional development wells in the producing fields is Saudi Aramco's standard practice to offset normal declines of older wells."
"This maintain potential drilling in mature fields combined with a multitude of remedial actions and the development of new fields, with long plateau lives, lowers the composite decline rate of producing fields to around 2%," the spokesman said.Now those of you who have removed your socks, will quickly calculate that this is still around 180,000 bd, or about half of the slated production from Haradh, but wait! This depletion rate INCLUDES the development of new fields. Oh!
And, another gentle cough and a quick visit to Baker Hughes tells us that they have 37 rigs drilling for oil and 17 drilling for gas. If the oil rigs are 90% successful and can drill 6 wells each a year, and each producing well averages 3,100 bd, then the new production they will generate this year is 37 x 6 x 3,100 x 0.9 = 619,380 bd, regardless of how big their reserves are.
Sharp cuts of $10 to $30 a barrel off the posted regional prices in the Williston Basin are being reported, and some producers have started to shut down wells rather than sell, even if there is room on a pipeline to ship it out.Part of the problem appears to be the current down-turn in refining capacity (we are in maintenance season as well as still being a couple or three refineries short after Katrina) that may be more locally tied to increases in production from the oil sands of Alberta that are close by. The discussion in that earlier post was sufficiently intriguing that I thought it worth bringing the topic forward.The static refining capacity in the United States, increased production in the Canadian Tar Sands and limited capacity on pipelines are among the reasons given for the steep pricing discounts. The Williston Basin straddles the northeastern Montana, northwestern North Dakota border. The highly productive Bakken field near Sidney is part of the basin.
"This is sending seismic shock waves through the Northern Rockies," said Tom Hauptman, a Billings oil and gas producer. "Some are being told, 'We don't want your product.' The posted prices are being discounted by $20.45 a barrel."
The next time you post look down at the html instructions beneath the "Post" button. To create italics, put a "<eye>" before the phrase you want italicized and an "</eye>" afterwards. I'm substituting "eye" for the letter "i" above.
These new rigs will include Jack ups and possibly workover hoists. One thing seems certain, You dont need to increase your fleet so massively unless you have or are about to have a problem with production flows.
So may be 16th December 2005 was the date after all?
Here's the curve according to Baker-Hughes:
Oil rig count has been cruising along in the 15-20 range for a number of years, and then takes a sharp upturn in the beginning of 2005. Besides being about the beginning of the global production plateau, if we compare that to Saudi production specifically (the green line is the JODI version of Saudi production), we can see that the sharp upturn in rigs begans right after a litle drop in production at the beginning of 05. The upturn in rigs has so far not resulted in any production increase to speak of.

Source: 1) A mate in SACo. 2) Recent presentation given at Bahrain. Of course, both could be wrong. But the remarkable headline at the Bahrain conference, was the level of intended expansion to 120 rigs. This did not mention type, or over what period.
My thoughts? If they need to extract heavier oils, then lots of rigs drilling vertically with steam - flushing may be the plan. Bottle brush drilling could be another way to try and ramp up lighter crude reservoirs. Some of these additional rigs may be intended for a major exploration campaign.
BTW: SA is not the only country in the region looking to ramp up the rig count all appear to intend to do so.
Rig builders, Service Companies etc look to be busy for the next few years.

Bank says Saudi's top field in decline
By Adam Porter in Perpignan, France
Excerpt:
Coxe dismisses Saudi claims that the country can produce extra capacity to satisfy surging demand. He notes that Saudi promises to increase production last year failed to materialise.
One of the key factors in the USGS statistical evaluation was that they could not find cases where the Saudi's had drilled dry holes - that is no longer the way it is.
8% decline without any more infield extraction? Sounds like a Hubbert Cliff to me. Adding more infield extraction only TEMPORARILY SLOWS this 8% decline, then when these new infield wells water out in a relatively short timeframe, then aggregate yearly decline jumps to what:
10%,12%,15%,20% ???? --Oh crap! And exports will decline even faster [Westexas & Khehab's theory]!
ARAMCO Quote: "This maintain potential drilling in mature fields combined with a multitude of remedial actions and the development of new fields, with long plateau lives, lowers the composite decline rate of producing fields to around 2%," the spokesman said."
Even Alan Greenspan must be impressed with the carefully conceived 'mumbo-jumbo' in this statement. Since when has any oilfield had a 'long plateau life'?-->Sorry, but the extraction profile follows a bell curve. The overall Saudi decline rate might be 2% for one year, 4% the next, 6% for postpeak year three, year 4 = 8% [now back to pre-remedial aggregate], then getting progressively worse each year thereafter. In short, M. Simmons's BIG STRAW THEORY being confirmed.

Exactly. The Yibal field in Oman is an exact correlative to the Ghawar and other fields in SA undergoing extensive advanced extraction techniques. The Yibal collapsed spectacularly.
The collapse of Ghawar is imminent. Three years at best and we will see double-digit production decreases.
Once you get a newbie to start breathing again they ask a lot of "but what about..." questions, and they pretty quickly get the mental model worked out.
Saudi Arabia is at 55% of Qt.
These were the two principal swing producers, and each one served as a swing producer for about 35 years. Texas, 1935 to 1970, and Saudi Arabia, 1970 to 2005.
I think that a useful plot would be 21 years of Texas production data, 10 years on either side of 1972, with 11 years of production data for Saudi Arabia also shown, lining Texas in 1972 up with Saudi Arabia in 2005, with different vertical scales. Since we only have crude + condensate for Texas, I would use crude + condensate for Saudi Arabia.
Imagine, if you will, what a Texas oilman--then proud of Texas' record high oil production--would have said in 1972 if you told him that oil prices beyond the dreams of avarice were just around the corner--a 1,000% increase in oil prices over an eight year period, that Texas would respond with the biggest drilling boom in history, that we would increase the number of producing oil wells by 14%--and oil production would drop by about 30% from 1972 to 1982.

Demagogic politicians like to blame "Big Oil" for the entirely predictable spring surge in gas prices. In truth, the politicians themselves bear a good deal of the responsibility for the price spike.
The underlying cause of the annual jump in prices is a shortage of refining capacity in the U.S. On an average day, Americans consume more oil than the maximum output of the refineries. Because the refineries are constantly stretched to their limits, even a small disruption -- for instance, a fire at one refinery -- can affect gasoline supplies and cause prices to rise across the country.
Supply bottlenecks sometimes are caused by aging refineries temporarily shutting down for maintenance. The U.S. refining system simply does not have enough capacity to deal with even routine events that affect production.
The last refinery built in the U.S. opened in the late 1970s. Faced with the enormous cost of building a single refinery -- more than $3 billion -- and the likelihood of lengthy delays in obtaining environmental permits, energy producers have been reluctant to expand the refining system.
That last sentence is only partially true. Permitting a new grass roots refinery is a nightmare. Expanding an existing refinery is not as difficult, and refiners are expanding.
A news story published last year detailed the difficulties a company in Arizona encountered in trying to build a refinery. Arizona Clean Fuels LLC began seeking state and federal environmental permits in 1998, but as of last fall, the company was still waiting for final approval.
"Someone needs to feel accountable for the schedule in issuing permits," Glenn McGinnis, the chief executive of Arizona Clean Fuels, told a reporter for the Knight-Ridder newspapers.
The system of environmental regulations that blocks new refineries and imposes other restrictions on the nation's gas supply was designed in Washington, D.C., with the approval of Congress.
Every spring, the refineries are forced to shut down to convert to the production of summertime fuels mandated by the federal Environmental Protection Agency. Under the EPA mandates, gasoline sold during the high-volume summer months in urban areas with relatively high levels of air pollution must contain pollution-reducing additives.
Not just that, but most of the butane has to be pulled from the summertime blends. Otherwise, your fuel might boil in the summer.
This year, the pressure on the refineries is even more acute, largely as a result of the energy bill approved by Congress.
The energy bill promotes ethanol as a cleaner-burning replacement for fuels with the additive MTBE, which was effective in reducing air pollution but at the cost of polluting groundwater. Gasoline containing MTBE has leaked from tanks, raising concerns about the additive's effect on groundwater supplies.
Unfortunately, the nation's ethanol producers are not yet ready to meet the increased demand caused by the abandonment of MTBE as an additive. A number of new ethanol plants are in the regulatory pipeline, but it may take years to bring them on line.
More states will probably ask for oxygenate waivers, as California did.
With an election looming this fall, politicians will soon begin lining up to blame the oil companies for the latest rise in gas prices. Undoubtedly, many of those politicians will be the same ones who voted to put severe restrictions on energy producers.
Motorists should keep that in mind when they pull up to the pumps and prepare to pay the hidden energy tax federal and state officials approved without admitting it to the public.
Yes, I am sure politicians will accept the blame for this, instead of pointing the finger at oil companies and accusing them of gouging consumers.

As one who has lived downwind of a refinery, I can understand the sentiments of others who do so.
I hope to live long enough to see the end of the age of oil and to see substitutes largely replace it as an energy source.
Personally, I would like to see this as well. We have to become sustainable in all aspects of our way of life at some point, or nature will take care of things her own cruel way. But I don't know what it is going to take. I think we could move to something like a biodiesel based economy, but our politicians won't have the guts to pull the trigger because our fuel prices will be higher, and probably a lot higher.
Then John and Jane Public will start complaining that their way of life is being taken away from them, that they can't afford to drive their 4x4 any more, yadda, yadda, yadda, and the politicians become fearful that they won't be reelected. So, it is probably going to take a real crisis, leading to super-expensive gasoline, before a true transition away from fossil fuels becomes politically palatable. My hope is that gasoline becomes very expensive long before we start to run out of it. I see that as our chance to make it through peak oil without a societal collapse.

Why were the regulations put in in the first place and what would the consequences be to the air, to groundwater, etc., if they are taken away? Would there be any adverse effects on global warming, on public health, etc?
What are the compromise solutions possible?
Are there other, more bureaucratic problems having to do with seeing the process through from the bureaucratic side, more so than the actual regulations being adhered to from the refineries' side?
Folks seem to be awfully calvalier in complaining about the restrictions of the EPA (referring to the above article and other similar ones, rather than the poster), with absolutely no discussion of the other side of the coin...
And certainly discussions here make clear that the underlying problems we are facing go a lot deeper, are a lot more fundamental, than EPA regulations on our refineries, although those do contribute in important ways to supply constriction.
Could folks more knowledgeable than I help me with the whole of the discussion above, which gets into both the effects on prices with/without current EPA regulations and also the effects on surrounding areas, etc. with/without current EPA regulations, and any other issues that may come up from such a discussion...
Thanks...
If an oil refiner could kill a few thousand people annually in order to slap together a piece of crap refinery, it would, but there are actual people out there who kinda like a clean environment, thank god, and they won't let them.
The answer does not lie in extending a flawed system, it lies in conservation, renewables, and sustainability.
I have a friend who has suggested the same thing to me. But I can tell you this. I have set in on many, many meetings where expansion plans were discussed. Not once has anyone ever suggested that there may be insufficient crude supplies to justify the expansion.
RR
Environmental regulations are certainly necessary, because you can't expect that everyone would do the responsible thing. I don't know the details of why it is so hard to permit a new refinery, but I have been told by a lot of people that it is extremely difficult (in fact, to this point nobody has successfully done it). I think a bigger problem is that nobody wants a new refinery built in their community.

What do you make of this following quote reposted from the initial heading post:
"Sharp cuts of $10 to $30 a barrel off the posted regional prices in the Williston Basin are being reported, and some producers have started to shut down wells rather than sell, even if there is room on a pipeline to ship it out."
Reads to me: if an oildrill company can financially afford it, they would rather sell the oil later for postPeak BigBucks, than sell it now for less. Self-limiting the market to maximize profits?
