Cement Remedial Grouting Procedure
If good returns were obtained at surface/seabed during the primary cement job, the casing to the drive pipe annulus should be topped up as follows:
- RUN a 2” tubing string down to the annulus as far as possible and circulate.
- SLOWLY PUMP the cement slurry (Class G cement mixed with 1.5 % CaCl2 mixwater) in the annulus until good cement returns are obtained at surface. POOH stinger. Note: STOP pumping if there are not returns after pumping 50 bbls of grout cement.
