Former Mobil VP Warns of Fracking and Climate Change

July 19, 2013

But not just climate change:

Methane release: fracking the planet’s future

So when you talked about “the race for what’s left,” that’s what’s going on. Both the horizontal drilling and fracturing have been around for a long time. The industry will tell you this over and over again – they’ve been around for 60 years, things like that. That is correct. What’s different is the volume of fracking fluids and the volume of flow-back that occurs in these wells. It is 50 to 100 times more than what was used in the conventional wells.

The other [difference] is that the rock above the target zone is not necessarily impervious the way it was in the conventional wells. And to me that last point is at least as big as the volume. The industry will tell you that the mile or two between the zone that’s being fracked is not going to let anything come up.

But there are already cases where the methane gas has made it up into the aquifers and atmosphere. Sometimes through old well bores, sometimes through natural fissures in the rock. What we don’t know is just how much gas is going to come up over time. It’s a point most people haven’t gotten. It’s not just what’s happening today. We’re opening up channels for the gas to creep up to the surface and into the atmosphere. And methane is a much more potent greenhouse gas in the short term – less than 100 years – than carbon dioxide.”
