YST-38S Positive Pulse MWD

YST-38S is positive Mud-Pulse MWD; the outer diameter is only 38mm, specially designed for small hole and re-entry sidetrack well.

The equipment transmits the obtained parameters to the surface through the change of the mud pressure.

The system with minimum moving parts extends downhole life and simplifies maintenance.

The downhole equipment is modular and flexible, which ensure to meet the need of short radius well. The downhole equipment is retrievable.
