Does this mean the tracking industry can sue for slander?
Poorly encased wells are to blame for water contamination in fracked wells, not the controversial drilling process, according to a new study. The BBC reports:
The researchers used noble gases to trace the path of methane as these inert chemicals are not affected by microbial activity or oxidation. […] By measuring the ratios of the noble materials to the methane they were able to accurately determine the distance to the likely source. […]
“The mechanism of contamination looks to be well integrity,” said one of the authors, Prof Robert Jackson from Stanford University. […] “In about half the cases we believe the contamination came from poor cementing and in the other half it came from well casings that leaked.” Read the rest of this entry »
