Product Description
3 7/8" Round Mandrel Slip Joint for Slim Hole DST Operations
The 3 7/8" round mandrel slip joint is engineered for slim hole well testing services and fracturing operations. This specialized tool compensates for pipe string movement caused by ocean heave, temperature fluctuations, and pressure changes during drill stem testing (DST), fracturing, and acidizing operations.
Key Features & Benefits
- Provides variable-length joint to accommodate pipe expansion and contraction during testing or stimulation
- Maintains tool placement stability by isolating vertical movement from drilling vessels
- Ensures constant weight on packer during testing or stimulation operations
- Facilitates proper spacing of testing string when subsea tree is landed
- Compensates for pipe string elongation and contraction in both offshore and overland operations
Primary Applications
- Drill Stem Testing (DST) operations
- Oil and gas well treatment work
- Well squeeze cementing operations
- Fracturing and acidizing operations
