Two-Pod Mill A conventional mill run was made with a 4 3/4-in. junk mill, but only achieved 8 ft (2.4 m) of penetration. A 4 3/4-in. two-pod mill was deployed and, in a total of four runs, completely cleaned out the well. • Mill 1 milled out 170 ft (52 m) in 35 hr, milling the balance of the stub (8 ft, 2.4 m) and 162 ft (49 m) of the cemented tubing.
