In one of our platform offshore well, we want to use drop in gyro (ALL-ATTITUDE DROP KEEPER (AdK)). Depleted sand in the 8.5" section poses downhole losses challenge and hence we need to include a PBL sub in the BHA. PBL sub ID: 2.7" OD: 6.75" ADk dia: 2"
Is it advisable to do drop in gyro when PBL sub is in the BHA? What will be the
impact of dropping this tool through the PBL sub? Will it damage the ball seat?
