- Drilling with Casing / Drilling with Liners
Description
GBCD Slim Hole connection is a slight modification to the GB CD Buttress connection design. With GB CD’s extensive field history, the Slim Hole connection provides the clearance you need, with the quality and performance you trust. Innovative, multiple taper buttress thread design (box only) reduces localized bearing stresses in critical areas for improved fatigue resistance. Pin noses meet in the center for positive indication of proper field makeup. Pin and box cross sections are balanced for higher efficiencies. Patent Pending
Features
- Proven and reliable Buttress thread form
- Excellent make/break repeatability under field conditions.
- Designed with regional BLM annular clearance requirements in mind.
- Tested in accordance with GB Connections Fit for Purpose (FFP) Test Program targeting Mult-Frac Horizontal Wells (MFHW).
