Tesco Cement Swivel
Engineered to compliment Tesco’s Casing Drive System™ (CDS™), the Cement Swivel provides an entry port for the cement between the CDS and the top drive. This combination of equipment allows almost immediate transition from casing running operations to cementing, and it also allows the casing to be rotated and reciprocated during the cementing process.

Applications
Dynamic Cementation: casing rotation while cementing


Benefits
Casing rotation while cementing
Reduces NPT
Improves mud displacement
Reduces channeling
Prevents gas migration
Provides better zonal isolation


Features
Smaller size takes up less derrick space
Side port allows instant transition to cementing after running casing
2-½” bore allows easy flow of fluid and ball
Portable tee auto plug launching system (addition)
A 6-⅝” reg pin screws into the TesTork or directly into the Top Drive, allowing rotation of the entire casing string during the cementing operation
A 2-½” bore enables easy flow of fluids through the swivel via the Top Drive when rotation is not applicable and via side port during Dynamic Cementation
Side port entry allows the flow of fluid while cementing and automatic ball launching using Tesco’s ball launching assembly
A 6-⅝” reg box connection attaches to the Casing Drive System, or CRT, enabling casing running operations while the swivel is in place and allows for immediate transition to cementing after casing running
