The report you refer to in your opinion, was accomplished not by experts, but instead was "prepared by" political antiche' of President Obama, and is hardly what I would consider credible. The Mining and Minerals Management Service in conjunction with API did an exhaustive study of HISTORICAL WELL RECORDS tracking ANY leaks that were reported from wells back to the mid 1970's. This study concluded that the history of LEAKS from wells were less than .01% in onshore installations were well intervention was used extensively. On the North Slope, the history is really quite conclusive, there were ZERO instances where fracturing of producing formations resulted in cross communication where that formations fluid was found elsewhere in the well. Virtually all leaks on the North Slope reported at surface in conjunction to FRACKING, have been the result of a failure of surface equipment or piping during the Fracking process.The ALASKA OGC ARE THE EXPERTS, NOT the Obama POLITICALY controlled EPA.
