Description

The solid body dart latch collar is a field-proven assembly designed to positively lock our latch-down wiper dart. Elastomeric seals on the wiper dart nose seal within the latch collar assembly to provide pressure integrity from above and below, while a locking slip firmly locks the dart in place. A solid no-go ensures the dart cannot be pumped through the latch collar assembly when pressure is applied from above.

Features

  • Fully configurable wiper dart design
  • Single-piece body with no potential leak paths
  • Millable internal latch insert
  • Positive locking mechanism
  • Solid no-go design

Benefits

  • Wiper dart can be configured in a variety of ways to accommodate monobore casing, tapered strings, liners, and ball-drop sleeves.
  • Locking mechanism prevents the dart from becoming unseated after the cementing operation to ensure the wellbore integrity remains intact.

Applications

  • Cemented liner and monobore completions
  • Cemented ball-drop sleeve systems
  • High-differential-pressure applications that require wellbore integrity up to 10,000 psi (69 MPa)
