| I saw (but did not read) a story in the NYT this morning whose sense was that even gas companies are starting to agree that fluids used for fracturing should be subject to complete disclosure. It seems to me that it is not the act of fracturing itself, but the choice of the wrong fluids that makes for real messes. My guess (as a mechanical engineer with some graduate work in fluid mechanics) is that a significant portion of the benefit from fracturing comes directly from the pressure that is applied, while secondary ancillary benefits accrue from choosing one fluid over another. If this is true, then much of the benefit of fracturing rock could be gained by using water. More hazardous fluids could be banned without doing great harm to the business. I don't think we have much choice: we have to extract the gas. And we have to prevent multi-billion dollar environmental clean-ups. |
