DuraSet Cement System
The Baker Hughes DuraSet™ cement system is designed to provide improved tensile strength and elastic properties while exhibiting enhanced mechanical properties. The use of specific additive combinations and, in some cases, foam offers improved flexural and tensile strength, elastic properties, and fracture toughness. DuraSet slurries can be used in the majority of casing or liner applications.
This approach enables design flexibility and takes elastic cement systems out of the lab and into the real world. DuraSet cement slurries are part of the Baker Hughes Set for Life™ family of cement systems, which are designed to isolate and protect the targeted zone for the life of the well. These slurries can be blended with other systems in this family to help ensure long-term zonal isolation.
Applications
- Critical primary cementing operations
- Fields with a history of sustained annular pressure
