No Methane or Earthquake Worries

I would like to address a few points in “Those Fracking Tunnels” in the Voices section.

Peer-reviewed university studies have demonstrated that well completion technology captures 99 percent of the methane produced at wells, meaning hydraulic fracturing is not a significant source of methane in the atmosphere.

Also, Richard Davies, a professor of Earth Science at Durham University in Great Britain, states that it is “extremely unlikely” that hydraulic fracturing will produce “felt” earthquakes. There is more risk associated with disposing of wastewater in injection wells, but oil companies are likely to recycle this water; there is a drought in California, after all.
