Well Cementing

Second Edition – Erik B. Nelson, Dominique Guillot

Without adequate zonal isolation, wells are unlikely to reach their full producing potential. The ultimate goal of cementing is to provide well integrity through zonal isolation—a durable hydraulic seal in the wellbore that allows selective fluid production from subsurface formations and prevents leaks into other formations or to the surface. As production companies pursue reserves in high-cost, high-risk environments, well cementing and sustained wellbore integrity are increasingly critical to the success of the reservoir exploitation cycle.
