I wonder if they can detonate the LPG? Here’s a report from Isabel Ordonez writing for Nasdaq. From the article:
“This fall, Chevron tested the use of liquefied petroleum gas (LPG) as a fracturing agent in five natural gas wells in its Piceance Basin development in northwestern Colorado,” Chevron spokesman Russell Johnson said in an email. “We are now evaluating the test results to determine the potential usefulness of the technique.”
Chevron’s test comes at a time when hydraulic fracturing–a technique also known as “fracking”–has come under scrutiny from environmentalists and others who fear it poses a threat to public health through groundwater contamination and air pollution. It also uses massive quantities of water, a concern in many Southwestern states currently affected by drought. Finding an alternative for water in the fracking process could be key for Chevron and other oil companies that have recently acquired large land positions in shale formations across the U.S. and Canada.
