Calcium Nitrate Tetrahydrate
Description of product
Calcium Nitrate Tetrahydrate is a highly soluble, crystalline compound widely used in the oil and gas industry for various applications, including well stimulation, cementing, and as a corrosion inhibitor. Its hygroscopic nature makes it a valuable component for controlling hydration and providing calcium ions in drilling and completion fluids.
Applications:
- Cementing Operations:Accelerates the setting time of cement in high-temperature and high-pressure wells.
- Corrosion Inhibition:Protects pipelines and equipment by forming a protective film on metal surfaces.
- Drilling Fluids:Stabilizes shale formations and enhances the fluid's ability to control water intrusion.
- Hydrate Prevention:Prevents the formation of gas hydrates in production pipelines.
