X3
Transfer
X3 multifunctional sub with stabilizer sections. Mid-length variant (1,225 mm). Runs in the BHA only — no surface Transfer sections — to suppress stick-slip and axial shocks at the bottom of the string.
Transfer lineup — operating effect
Stabilizing sections are kinematically decoupled. BHA-only — cuts torsional and axial shocks at the bit.
Kinematically decoupled stabilizer
Stabilizing sections rotate and shift radially relative to the body. No reactive lateral load transferred to the drill string.
Composite-reinforced bearing module
Adaptive floating bearing section reinforced with composite rings. Damps axial and torsional shocks.
Constant flow ID
Low pressure drop inside the sub. No impact on mud flow rate or mud motor operation.
