Formula for preparing one (1) barrel of SuprSeal LCM weighted slurry with either fresh water or seawater:
- Pull drill pipe and remove bit. Pull pipe safely above loss zone or into casing. Keep pipe moving if in open hole.
- Mix approximately 50-100 bbls of slurry and pump into hole. This product requires only water and a good mix.
- Pull into casing and fill hole through fill-up line. If hole does not fill, mix another slurry and repeat the above procedure.
- If hole stands full, close BOP and pump at a 2 bbl/min rate, until obtaining 300-500 psi holding pressure. If no holding pressure is obtained, wait two (2) hours and resume operations.
