This quick fishing operation prevented long delays and reduced the risk for this large project. The traditional approach would be to attempt using non-magnetic fishing tools with uncertain success, and in the worst case to use a mill to grind up the lost cones. This would however create a large amount of steel cuttings that would not disappear in a granite formation hole, and that eventually would cause more trouble for the next drill bit/hole opener.
“Innovar supplied a fishing magnet and retrieved all junk from the well on the first attempt. With our conventional tools and methods, this would have taken more time and taken several attempts. This saved us money by avoiding lost production. Thank you Innovar”.
