Frac Isolation System
The Frac Isolation System is used when fracturing pressures will exceed the rated working pressure of the tubing head. The frac isolation system consists of three components:
- a modified 7-1/16" 5,000 psi WP Type T tubing head with an isolation sleeve profile
- a frac isolation sleeve with field-proven, 10,000 psi rated seals on the OD and BPV threads in the bore
- a frac adapter which transitions from the 5,000 psi tubing head to the 10,000 psi frac valve
Frac isolation sleeves are available for use over both 4-1/2" and 5-1/2" production casing.
Features –
- Isolates the tubing head rated for 5,000 psi from fracturing pressures up to 10,000 psi
- Isolation sleeve can be safely removed from the wellhead under pressure
- Isolation sleeve and adapter can be reused for multi-well programs
- Lower cost compared to rental of conventional frac isolation tools
- Standard T tubing head bowl accepts all WGPC tubing hangers for subsequent completion
- Frac adapter for 5-1/2" available with optional 1-13/16" 10,000 psi outlets
