Test # 1 in pilot & 3in vertical WOB, lbs Target 1 L = 2,D=2.25 25-28 Yes 2 L = 2,D=2.25 23 - 35 3 inches above bottom 3 L = 4, D= 2.25 (@1in), 1.5 in (@3 in) 23-30 3 inches above bottom ` 4 L = 5, D = 1.5 (@1- 5 in) 16-27 Missed; bottom hole, interference from well - More WOB? 5 L = 4, D = 1.5 23-28
- SD, pneumatic threads came off
- Not enough displacement, so more
WOB
- Allen screws came off BHA
6 L = 4, D = 1.5 23-33 Stopped; torqued up (Allen screws), epoxy broke 7 L = 4, D = 1.5 20-33 Yes, 14 min 8 L = 4, D = 1.5 20-33 No - inserts, abt 20 min 9 L = 4, D = 1.5 20 - 49 Yes, optimized; 11 min
