Natural Fracking: How Long Did It Take?

Hydraulic fracturing is in the news because more natural gas has meant substantially fewer carbon emissions - and it has also been implicated in a variety of environmental issues. Man is doing what nature has always done, albeit on a different time scale. A new GSA BULLETIN study  examines how long it takes natural Earth processes to form hydraulic fractures and whether the formation is driven by sediment compaction, oil and gas generation or something else. Plus, in order to make environmental models about modern hydraulic fracturing production, it's important to know what role these natural fractures play. read more
