I think that fracturing rock in California and the potential earthquake risk posed by these drilling techniques is worth discussing.
Is there a fault close to the drill site? If there is, there may be a risk, depending on the type of drilling being done. If we can drill into the largest fault in the state, then there appears to be a large degree of variability even with what kind of drilling can be safely done. If there isn't even a fault nearby, then I doubt it'll be an issue.

As I said a few posts up, we are having earthquakes in Texas that we NEVER had before the new natural gas drilling techniques started being used.

Here is a story about a geothermal project in Switzerland shaking things up.

Here is an interesting blog entry with a link to a NYT times story discussing this issue in more detail.

Quote:
BASEL, Switzerland — Markus O. Häring, a former oilman, was a hero in this city of medieval cathedrals and intense environmental passion three years ago, all because he had drilled a hole three miles deep near the corner of Neuhaus Street and Shafer Lane. He was prospecting for a vast source of clean, renewable energy that seemed straight out of a Jules Verne novel: the heat simmering within the earth’s bedrock.

All seemed to be going well — until Dec. 8, 2006, when the project set off an earthquake, shaking and damaging buildings and terrifying many in a city that, as every schoolchild here learns, had been devastated exactly 650 years before by a quake that sent two steeples of the Münster Cathedral tumbling into the Rhine.

Hastily shut down, Mr. Häring’s project was soon forgotten by nearly everyone outside Switzerland. As early as this week, though, an American start-up company, AltaRock Energy*, will begin using nearly the same method to drill deep into ground laced with fault lines in an area two hours’ drive north of San Francisco.


Quote:
Power companies have long produced limited amounts of geothermal energy by tapping shallow steam beds, often beneath geysers or vents called fumaroles. Even those projects can induce earthquakes, although most are small. But for geothermal energy to be used more widely, engineers need to find a way to draw on the heat at deeper levels percolating in the earth’s core.

Some geothermal advocates believe the method used in Basel, and to be tried in California, could be that breakthrough. But because large earthquakes tend to originate at great depths, breaking rock that far down carries more serious risk, seismologists say. Seismologists have long known that human activities can trigger quakes, but they say the science is not developed enough to say for certain what will or will not set off a major temblor.

Even so, there is no shortage of money for testing the idea.
Whether or not it'll be an issue really depends on the specifics. W/o those you're just shooting in the dark.

This isn't Pakistan. California has earthquake standards, in case you didn't know. :|

Most of the quakes on that list are well over 5.


Just a joke, hence the bit about celebrities.

**My late comment to the debate over Energy Return On Energy Input (EROEI) vs. $$ in vs. $$ out on page one of these comments.**
I don't think a discussion of EROEI and economics are drastically different - BTUs have a price (sometimes based more directly on the 'cost of extraction' other times simply on supply and demand...like current nat gas prices). You're not likely to build a wind turbine using power from a wind turbine because it is more economical to use an energy source that is easier (less expensive) to harness.
Cable tools - powered by steam from a wood or coal burning stove - were an improvement over shovels (by both measures, or you wouldn't do it). Diesel-powered rotary drilling rigs can easily tap into oil reserves for $8 to $20/bbl - it is economic and you'll get a lot more BTUs out than went in (even when you allocate the BTUs needed to mine ore to make the steel to pay the person to construct the rig, etc.)
St. Olaf College did a good study on the EROEI of bio-diesel and ethanol where they burdened the resulting BTUs in the end-product with the BTU 'costs' of building the tractor to plow the field and plant the corn plus construct the facility to brew the fuel and to 'power' the labor to drive the tractor, etc. Net was a positive EROEI - 1.6 BTU's out for biodiesel for every 1 BTU in (too bad that using the whole U.S. corn crop just for bio-diesel would only offset 12% of diesel fuel demand - so no Corn Flakes, tortillas or Jim Beam.) Now with the time-value of money, the economics might not be there, nor would you choose that option if you can deploy those same dollars to a better return on the $$ (like coal or oil).
As for the earthquake discussion, anyone remember the deep water disposal at Rocky Flats near Denver in the 1960s that resulted in some quakes?

Why would you want to throw in another variable like EROEI when the basic business case involves so much estimation?
I think many of you don't even have the basic idea of how E & P dept's of oil cos. work.


People tend to like to mishmash moderately related concepts into one big "it". The reality is much more complicated.

If one asks the question, "will and should the field be developed?" It is strictly an economic decision, with as you noted, enough unknowns to give all but the toughest souls, weak knees. If, in the end, they believe they have good odds of returning a profit, the field will be brought into production.

A separate question, "does bringing this field to market increase or decrease the total energy available to the economy?", is more structural, related to if and when a grid collapse might occur. As long as the EROEI is approximately neutral or better, the field can be considered a net asset to the overall energy situation of the country. Once fields that are strongly negative become economically profitable to bring to market you end up in a situation where the fields are energy liabilities, but required because the FORM of the produced energy is simply too valuable to pass on. So EROEI can be considered a macro economic benchmark; but it is not particularly useful when reviewing whether a field will be profitable, and whether that field will produce an economic benefit that enables continued ubiquitous transportation capabilities.

BigTex, Dude what are your collective problems? Are you luddites or something? Do you want us back to the cave dressed in furry non-animal-product naturally-woven fiber loincloths?

Don't bother answering. I have a Tea Party to go to.

I think you are responding to a post in another thread, but I'll give this a shot...

I have this idea that there is some way of creating a sustainable society (by sustainable, I really just mean one that could last maybe 50-100 generations). One of the challenges to overcome, however, will be our tendency to celebrate our cognitive abilities without taking a hard look at whether our current ecological predicament isn't the result of basically cleverness run amok where the complextiy of our solutions creates exponentially more complex problems in their wake.

I suppose that earthquakes triggered by new drilling techniques is one example of this tendency to come up with solutions that create heretofore unknown problems (i.e., human-induced earthquakes), which in turn will require ever-more complex solutions (e.g., new earthquake resistant building designs for areas in which drilling activity will be conducted).

***

RE cave living, while a natural fiber loin cloth would be fine, I think I would also look good in a full grain leather style (perhaps a puma pelt).

In a back-to-the-cave movement, I would probably be inclined to play the whole field on loin cloth designs.

I was being facetious. I believe you are talking about 'solutions in isolation' and our predilection for looking with a short-term perspective. While this works in the modern business world (where fashion trends and consumer electronic products do change often) it definately is not a good approach on a planetary level in an overpopulated world.

Whoever thought that hair spray and refrigerant would burn a hole in the ozone layer and make old ladies and young birdwatchers where floppy hats? It's all a function of too many damn people.

Zero population growth and depersonalizing corporations once again (taking away their right to speech, especially campaign contributions and lobbying) has got to be our goal.

So just get rid of the sex drive and greed, and humanity ought to be okay.

on the resistance to drilling: this is Bakersfield, not santa barbara. There are huge areas with pumpers on a very fine spacing and steam-drive production. I think there won'be too much resistance. Hydrofracing is very common already.

I just checked out the Venoco website and it looks like their focus is on the near-shore areas off the coasts of Santa Barbara and Los Angeles counties. Judging from their maps it would seem their focus will be on redevelopment from existing offshore platforms? However . . .

>>> Click on the 09/04/09 Presentation <<<

Page 16 is where they tell us their leases in the Monterey Shale contain 10 billion bbl OOIP - the footnote says that is in onshore leases - but onshore where? Can't tell from the write-up. They say the entire shale in "Southern California" contains 290 billion bbl OOIP. Would be nice if they included a map showing where this thing is located.

Here's where I got the Bakersfield location:

Not sure how areally extensive the play is. Bakersfield is at the southern tip if the SJ valley

Looks like there's another company interested in poking some holes into this shale - though this is a small, Utah-centric gas-focused company and they're looking for a partner for their California prospects. At any rate, this gives us a bit more idea of the areal extent of this shale -- this company's CA properties are in the Antelope Valley, which is the area around Palmdale and Lancaster. A bit farther south than the aforementioned Bakersfield area.

Antelope Valley Trend

Gasco has identified six separate prospects in the greater Antelope Valley Trend. This trend is one of the few remaining areas in the San Joaquin Basin prospective for large untested anticlines and other structural traps with established reservoir targets and source rocks. The moderate-depth targets are the Monterey Formation sandstone and shale, the Temblor Formation (including the Carneros sandstone), the Point of Rocks and Mabury (Gatchell), and Lodo sandstones which range from 800 feet to 12,500 feet. The total unrisked gross potential of all seven prospects is estimated to be more than 850 MMBO and 2.2 Tcf of natural gas.

The Sawtooth Ridge Prospect is a large anticline below the Antelope Valley thrust that is delineated by seismic data, surface geology, well data and cross sections. The total unrisked gross prospect potential is estimated to be up more than 500 MMBO and nearly 1.0 Tcf of natural gas from the Temblor, Point of Rocks and Mabury sandstones.

The West Shale Hills Prospect is a seismically defined anticlinal trap. The total unrisked gross prospect potential is estimated to be more than 300 MMBO and 275 Bcf of natural gas from the Temblor, Point of Rocks sandstone and Mabury sandstones. In addition, the oil-saturated Monterey shale section may be prospective for horizontal drilling applications.

Time for an update! :-D

Was just reading Venoco's 3rd quarter conference call transcript where the CEO outlined their plans and ideas for this play.

>>> Seeking Alpha <<<

On that page he talks about their leasing plans. They're also talking to some potential partners, but will go ahead even without them. But if they do get a partner they can double or triple their drilling plans. Anyway, he then discussed the geology and engineering:

Quote:
[...]

The interesting this about this exploration play targeting the Monterey Shale is that the formation is fairly well defined. Thousands of well bores have been drilled (inaudible) oil to the Monterey Shale in Southern California including on and around our leaseholds. As a reminder to people, this is not exploration in the typical sense of looking for the hydrocarbon because we know they are there. With the information we have, we believe our leases to have an excess of 10 billion barrels of oil in place. As we said, we are not exploring with oils, we are really more looking at drilling and completion techniques that will replicate productive capacity we see in the naturally fractioned Monterey Shale offshore. We can imply our Monterey Shale expertise came from producing the naturally fractured shale more than (inaudible) and South Ellwood and Sockeye field. Offshore we are learned that the Monterey Shale is complex with mixed lithology. Shale (inaudible) and sandstone can influence reservoir response making it seem quite diverse.

Productivity capacity of Monterey Shale is very exciting because unlike other shale plays the zone is extremely thick. Our South Ellwood field Monterey Shale is nearly 2000 feet thick and the same is true for a good portion of the onshore Monterey Shale. Monterey Shale formation is a proven and rich source rock in Southern California responsible for an estimated 38 billion barrels of recoverable oil, with a generative capacity as much as 290 billion barrels. As exciting as Monterey Shale is to us, we believe it will take some time to complete our lease and goals and again drilling and completing wells. We anticipate a very active drilling and seismic effort onshore California for Venoco in 2010. Further reminder is for those who have seen our presentation there that we are also focused on medium gravity to light oil from the 25 to high 30 in terms of API [ph] gravity, so this is good quality oil.

[...]

So, that answers an earlier question I had about the gravity of the oil here. This is better-quality stuff than in most of California's conventional fields.

Later in the conference call he says they'll start some drilling in this shale in January but they won't start doing some more intensive work until later in the year after they've examined the results of the first few wells.
