Cogco used 80 grain det cord wrapped around the tremmie pipe, we filled the well with grout <br /> through the tremmie, placed a water filled drum on top and set it off. It was very anticlimactic-a bit of a "whump" <br /> which was fine with me :) <br /> Casey <br /> Sent from my iPhone <br /> On Jan 8, 2014,at 4:11 PM, "Adrienne Ellsaesser [EH]".<AEllsaesser@scehd.com>wrote: - <br /> >Casey, _- <br /> > <br /> > If the well cannot be over drilled,than explosives are the next step <br /> >towards meeting our destruction standards.A small diameter PVC trime <br /> >tube that has the detonation cord (with enough charge to break up the <br /> >2 inch PVC casing; i.e. 50 grain special or 100 grain) attached to it <br /> >can be placed into the well from 90 feet to 3 feet bsg.
