Study produces supercement for annular seal and long-term integrity in deep, hot wells

The results of this study produced improved sealants for HPHT wells. Pre-stressed cement is applicable for primary cementing applications while UltraSeal R Sealant is useful as a remedial sealant. Application of these sealants in HPHT conditions should result in significantly improved annular seals. In turn, the resulting well operation should be easier and more effective with fewer interventions to repair gas leakage.
