Re: Does the extraction of natural gas require oil?

Unread postby funzone36 » Sun 08 Jul 2007, 19:51:09

LNG transportation requires oil. Lots of them since it's heavy and transporting it to the US means travelling half a world away.

The problem is not natural gas supply, indeed. The problem is price and demand.

By the way, the EROEI for methane hydrates is bad and it risks more climate change.

Even though there are large natural gas reserves, North American natural gas has already peaked. Russian natural gas exports are also falling: http://www.interfax.ru/e/B/0/26.html?me ... e=11726091

There will be tons of natural gas long after we hit peak natural gas. The problem is, how much can we extract.

Lastly, natural gas suffers from the same problem as oil. A lot of natural gas cannot be extracted because it is too contaminated.

$this->bbcode_second_pass_quote('', 'O')ne-third of the natural gas reserves in the United States cannot be used because of excessive contamination with nitrogen and/or carbon dioxide.

We can obviously purify it but the ultimate question is, is it economical to do that?

It's also possible to use natural gas in some combustion engines. The only drawback is that it takes 8 hours to fill it up.


Where did you get this? Or are you joking?
In the early '80's I drove a tow truck for a while. It was a 1981 GMC 1 ton, powered by a 350 cubic inch engine. It was dual fuel, gasoline or natural gas. (Not propane, natural gas. I have also run propane vehicles.)
It had two gas bottles mounted to the Holmes wrecker deck, which took about 2-3 minutes to fill. They were pressurized to some high number, on the far side of 2000 psi as I recall.
The system worked fine, although there was a lack of power on the NG, and you couldn't go far. It was good in town, but on a long highway tow I would have to switch to gasoline. I think range on NG was maybe 120 miles or so, but it was a long time ago, so don't hold me to it.
AFAIK any IC engine, including diesels, can be converted to NG, although gasoline engines are the easiest.

$this->bbcode_second_pass_quote('Tyler_JC', 'T')he world has X units of oil. Who will be more willing to pay Y dollars for those units?

Average Joe's RV or the natural gas producer?

Yes, the NG producer, of course, but that is not the point. Who will he have to sell it to if RV Joe is out of a job because the high cost of energy has crippled the economy? Besides where is all this NG going to come from? North America is due to peak, and given the complexities, and costs, involved in shipping the stuff as LNG, obtaining it from elsewhere (assuming a) spare saleable supply could be found, and b) terminals were available to receive it) is obviously not going to help the Americans with their local NG peak now, is it? That’s why the US is cranking out new coal fired power stations like there’s no tomorrow.

And that ignores the vast quantity of methane hydrates available under the oceans.


These Sir, are a Pandora's Box that you do not want to f*** with.

Here is but one article of hundreds that explain why:
http://www.mbari.org/seminars/2001/summ ... nnett.html

http://www.google.com.au/search?hl=en&q ... arch&meta=

One recognized issue is that, more often than not, hydrates play a critical role in the geological stability of the immediate shelf on which they lie. Take them away and you have the potential for hydrate dissociation, accelerating global warming. OR the best Hawaiian surfing competition you will EVER attend.

The ME has begun to build NG to liquids plants; does that answer your question? The funny thing is the NG industry is still somewhat immature. Everyday (and night) in Nigeria for one, NG is "flamed" off. It is expensive to store and transport, as other posters have noted, hence the NG to liquids industry.

Natural Gas was considered a nuisance in the oil industry until about 40 years ago. In the early days of the oil industry, wells often caught fire after hitting a reservoir because of it. When a wildcatter would hit NG, they would generally abandon the well. In other worlds, they would just let the well vent into the atmosphere because it was too dangerous to work around. Back then, home municipal gas was made from coal. The left over waste coal was mixed with water and cooked in a reactor. The chemical reaction would give off CO and H, which was piped to all the wealthy households. This type of gas was very dangerous, as CO is poisonous and is heavier than air. Modern NG is methane, which is lighter than air and hence much less dangerous in the home. Any leaks will quickly dissipate into the upper atmosphere.

Methane from Wikipedia. We're adding a bit each year, all those ruminants for one thing.

Imbalance (trend) +20 ~2.78 Tg/ppb +7.19 ppb/a

$this->bbcode_second_pass_quote('', 'M')odern NG is methane, which is lighter than air and hence much less dangerous in the home. Any leaks will quickly dissipate into the upper atmosphere.


Emissions from energy use are about half of that emitted by wetlands, and slightly behind those darn ruminants. The biggest sink (according to the Wiki article) is Tropospheric OH. Let's hope we don't find a way to break that stuff down...

There are a couple pilot projects to extract methane hydrates, the Japanese have one going. Could be bad news for all of us, including cockroaches.

" Natural gas can’t be used by most vehicles, though there are Fed Ex and other vehicle fleets running on natural gas currently. It can take up to 8 hours to fill a tank up with gas – it needs to be forced in and pressurized to be dense enough to power a vehicle. "

http://www.energyskeptic.com/Energy_In_A_Nutshell.htm

So, who do you think is telling the truth?

Update to all:

I emailed Alberta Connects for some information and it has been confirmed that the maintenance of natural gas facilities and drilling rigs require oil.

$this->bbcode_second_pass_quote('', 'P')robably the engines that run the rigs, the lubrication of the various parts of the drilling rig, and lubrication of compressors (typically run by gas turbines) that suck the gas out of the well, lubrication for pumps, electric motors and moving parts of equipment.


Indeed, some parts can still just use electricity (engine, motor) but the rest must use oil. Nevertheless, lubrication is still required for correct operation of engines and many other mechanical systems where parts must slide over each other without seizing.

I don't think I need to explain that the maintenance of natural gas pipelines also need oil. They do break down. For example, BP shutted down Prudhoe Bay because of pipeline breakdown.

For those who wants to know why lubrication is important:

* Keep moving parts apart
* Reduce friction
* Transfer heat
* Carry away contaminants & debris
* Transmit power
* Protect against wear
* Prevent corrosion


It feels ironic that in the end, only research by myself allowed my question to be answered.

Oil sands extraction without using water + using less energy

Unread postby Oil-Finder » Thu 31 Jan 2008, 23:03:40

I posted this in this thread here, but I think this is important enough to warrant its own thread here in the Energy Technology section.

Peakers and doomers like to cite the restricted availability of water from the Athabasca River as one of the obstacles on the amount of oil that can be extracted from the Canadian oil sands. Unfortunately for them, human ingenuity comes to the rescue once again!

First, we go here:

--> Suncor Energy says oilsands expansion will go ahead <--

Noteworthy, with the emphasis on the bolded item:
$this->bbcode_second_pass_quote('', 'E')nvironmental concerns played a large role in planning for the expansion, George said.

"We've worked very hard here in terms of continuing to reduce and minimize our impact on water land and air resources,'' he said.

George said Suncor has already reduced its water use 50 per cent per barrel over the last five years and there is no new increase in its licence to take water from Athabasca river.

Because Voyager will rely on in-situ mining at the Firebag reservoir, rather than open-pit mining, less land disturbance will be caused and George said Suncor will continue to invest in technology to reduce greenhouse gas emissions, already down 50 per cent since 1990.

Suncor will use the steam assisted gravity drainage, or SAGD, process to get the oil out of the ground. That method uses ultra-hot steam to heat the bitumen up underground, making it thin enough to draw to the surface.
. . .

George said Suncor would also look into other technologies, though he didn't specify which kinds.

One promising method could be Toe-to-Heel Air Injection, patented by Petrobank Energy and Resources Ltd., which uses air and the bitumen itself to heat underground reserves. The THAI process requires no water and uses up significantly less energy than SAGD.


Now, let's find out a bit more about this Toe-to-Heel Air Injection, a.k.a THAI . . .

--> Toe-to-Heel Air Injection <--

Highlight:
$this->bbcode_second_pass_quote('', '.') . . THAI™ uses a system where air is injected into the oil deposit down a vertical well and is ignited. The heat generated in the reservoir reduces the viscosity of the heavy oil, allowing it to drain into a second, horizontal well from where it rises to the surface.

THAI™ is very efficient, recovering about 70 to 80 per cent of the oil, compared to only 10 to 40 per cent using other technologies . . .

Another doomer objection debunked.

Of course they will find ingenious ways to extract the last morsel from the ground so as the 6 billion may get a chance to ride the new age of concrete and tarmac as far as the eye can see. Duh!

we've actually all been watching Petrobank and THAI for a while now. They have one of the few technologies that may make a difference in the downside of the PO curve if they can prove the technology is scaleable and usuable in a wide range of sites (which they haven't yet).

Ultimately its highly doubtfull that THAI will be able to replace the minimum decline rate of 2%/year of 86Mbrls/day. Just remember thats 1.72Mbrls/day with a growth rate of 100%. Right now I believe the Whitesands project (the only operating site) is producing 5000brls/day

And all that still doesn't address what all this new oil production is going to do to global warming which appears to be accelerating beyond worst case scenerios already.

Their symbol is PBG.TO
[web]http://chart.finance.yahoo.com/c/3m/p/pbg.to[/web]

They finally broke $50 so they've just broken through their resistance point. But with a P/E ratio of 92 they're very speculative. But considering their potential a good stock to buy once we get through this little banking crisis/financial meltdown.

This already has a thread in the Energy Technology section. And I posted the link to this thread in a response to you last week, but if you skimmed over that response and discovered this subject on your own, well good for you...

So far the THAI discussion has gotten into likely trends for this technology, the pros and cons (like accidentally starting massive uncontained fires) and it's successes in the recovery of energy from thin coal seams, spent oil wells and oil shale. And the thread includes pictures of the latest full scale THAI installation.

This is an old topic and a method which will pump even more hydrocarbons into the atmosphere. Which is a fairly doomerish scenario...

Also being the calm introspective person that you are, I'm sure you didn't mean to upset anyone with that declaration. But if you did mean to, we have a section of the site dedicated to arguing and insulting posters, it's called The Hall of Flames. When people want to start arguments, they often post there.

Sorry steam_cannon, I missed the other thread.

$this->bbcode_second_pass_quote('steam_cannon', 'T')his is an old topic and a method which will pump even more hydrocarbons into the atmosphere.

If they can figure out a way to get 70%-80% of the oil out of the sands with this method, I have great confidence they can figure out a way to reduce the amount of hydrocarbons this process will produce.

But at the very least, this addresses the water issue, which is still being repeated frequently on this forum despite the aforementioned thread already discussing this topic.

Yeah that's a good point and worth repeating. The water issue is becoming a problem for current technologies, but Toe to Heel may be the new way of doing things. So yeah, spread that around. This won't solve todays problems, but five or ten years from now this will probably play a big part in the oil, gas and coal industries...
