I believe they need to use a fluid that is viscous enough to stay in place after being pumped into the rock, so that the fissures do not immediately close when pressure is released.

- DigitalJack 13y agoIf you read the article, you will find that the contamination is methane. That is the has they are extracting. It's not the fracking fluid.
- jlgreco 13y agoI'm not particularly interested in fracking one way or the other, I'm just answering his question. They apparently don't just use water, like some people might expect they could, because it doesn't work. Many people are concerned about contamination from the fracking fluid, correctly or not.
- johnward 13y agoI'm more concerned with contamination from fracking fluid than I am with gases. This article didn't tackle fluid or the disposal of it. There are wells drill specifically to store fracking fluid.
