Deformable fabric sack w/ swelling agent enclosed.
Appearance: Sewed expandable fabric bags containing super absorbent granules that expand when hydrated.
Performance to expect:
- When experiencing low return or no returns, when drilling thief zones.
- To gain normal circulation apply a measured amount of the prepared sacks containing swelling agent down the drill pipe.
- When bags inter caverns and beads expand pressing against the wall and each other it is possible full return will be gained.
Note: Down hole assembly must be removed and drill pipe returned open ended for application process. Measure must be taken to eliminate bridging in drill string.
