Product Description
Well Testing Cased Hole Mechanical Packer Full Bore DST Safety Joint
Product Overview
The Retrievable Safety Joint is a full-bore safety component designed for drill stem testing operations in well testing applications. Compatible with Halliburton RTTS specifications, this emergency disconnect equipment provides reliable backup when packers become stuck during operations.
Operation Mechanism
Installed directly above the retrievable packer, the safety joint enables retrieval of all tools above the packer if the workstring becomes stuck. Release is initiated by parting the tension sleeve through upward pulling force, followed by vertical movement and rotational cycles for complete disconnection.
Primary Applications
  • Cased Hole Drill Stem Testing Operations
  • Tubing-Conveyed Perforating (TCP) Operations
  • Well Completion Operations
Key Features & Benefits
  • Positive operation sequence prevents premature release
  • Enables retrieval of DST tool string above safety joint when stuck
  • Full-bore design maintains flow capacity
  • H2S service compatibility per NACE MR-0175 standards
