Also effective is adding one bag of Magma Fiber to the suction pit every 30 to 45 minutes, after initial seepage has been controlled, as maintenance.

Let hole stand static for three to four hours, keeping hole full of fluid by adding to the backside of casing from the surface. After letting pill set for the 3 hours if wellbore is staying full, stage pipe back to bottom and circulate pill out of well. If the well is still taking fluid run pipe back in and pump another pill and repeat process.
