Hi Bobi,

 

I posted an entry about propane fracking last week.  We had some good replies and I am always interested in something that promises to be improve the fracking process. It does cost more - but water is becoming more scarce and the propane can be recovered in a closed loop system.  I think it should be studied more. 

 

I'm also glad to see another example of the creativity that is in this industry.  People are jazzed about shale and the field is wide open.  Most new ideas won't work, but a few will.  It's important to encourage that creativity because it will benefit all of us.

Seems amazing they can keep anything liquid during fracing considering the temperatures and pressures down there..

actually, a pressures increase it is easier to keep things liquid. as temps rise you need more pressure.

I pray that something works. I don't want the fracking to stop but if they don't find a way to frack without water I will be drinking recycled urine. http://www.huffingtonpost.com/2011/08/05/texas-town-urine-recycling...

ah, yeah. this is partly why I am so interested in alternatives to using water. This kind of technology, to drink cleaned urine, may become vital in the drier areas of the world.

 

A prolonged drought teaches us to value water ... and air conditioning from safe, clean natural gas!

the title to this is a little misleading...

 

They intend to recycle wastewater, which is prety much just water with some small percentage of contaimants that must be removed.

 

I would,'t drink water out of Cross Lake either, but after treatment its ok with me.. pure wastewater just needs more filters, or better yet, membranes.

Is Shreveport's Cross Lake city  water filtered?

Baron:

 

Has anyone ever analyzed the potential use of this frac method at HA/BO depths (bottomhole temps 132-177ºC) considering Tc of propane is 96.9º C).

As a comparative at depth and typical bottomhole temperature, would generally consider n-butane (Tc of 152ºC) a better match for conditions, if not more economical.  Availability in large volume may pose a problem however.

Here is a follow up article from Chemistry World News.  They don't mention explosions at all - but they do say it's 20-40% more costly to use propane than water.  But, I was expecting it to be a lot higher cost. When amortized over the life of the well, the increased costs is fairly low (according to CWS)

Here is an interesting article about Halliburton's new fracking fluid that is from enzymes found in fruits and vegetables.  This is what the exec drank on camera a few months ago. (which was a dumb PR thing to do because everyone simply thought he was crazy or well paid, not that the fluid was safe.  We had a discussion on GHS about it)

 

the article below is still an interesting read.

This company says they can reclaim 85% of the water. See atricle
