Casing Leak Repair

Goal: To restrict ground water in the well, to improve the quality of casing leak repair, and preserve the well productivity.

Achieved : By creating a sealing barrier to prevent the lost circulation and producing formation damage while pumping cement slurry to close the leakage.
Sealing barrier is formed by gel producing products (NMN and electrolytes). Next to gel producing product cement slurry with special additives and neat cement slurry are pumped down through casing leak.
This technology is used during work-over operations.
