FST™ Floating Sub Tool

Volant’s FST™ tool is designed for casing drilling or running operations with top drive-equipped rigs to supply passively damped axial travel during connection makeup. The FST tool helps to prevent damage caused by jarring or sudden loading to casing or drilling equipment during day-to-day operations.

  • Limiting load applied to ~3x joint weight circumvents need for an aluminum stump guide, contributing to faster run times.
  • Architecture can provide full hoisting loads in combination with full torque values at all stroke positions.
  • Compensates for makeup loss from drill collar or casing connections.
