Drill Pipe Darts

Drill pipe darts (DPD) separate the cement column in the drillstring and activate/release the wiper plugs. We offer a range of DPD to meet the requirements of your operations.

Solid-body latch collar and wiper dart

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/benefits

• Fully configurable wiper dart design
• Single-piece body with no potential leak paths
• Millable internal latch insert
• Positive locking mechanism
• Solid no-go design
• Wiper dart can be configured in a variety of ways to accommodate mono-bore 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.

Drill pipe dart with wiper ball

For the duo-wiper plug system, one drill pipe dart is pumped before and behind the cement column. With the single-wiper plug, only the drill pipe dart behind the cement column is used. Our sponge-ball drill pipe dart provides outstanding sealing properties in the drill pipe combined with optimal cleaning and wiping efficiencies across a range of sizes.

Features/benefits

• Available for all drill pipe sizes
• One-size string or combined string
• Available with lock feature
