Save hours of shearing time

The Mud-Shear Sub enables substantial time savings on mud conditioning prior to commencing milling operations. With the milling assembly run in up to the penultimate stand, the Mud-Shear Sub is installed just below rotary table. By pumping through the sub, rapid shearing can be achieved, this is often done in conjunction with an open CircSub above the mill.

This simple and low cost insertion offers a better alternative to configuring topside equipment or the time lost waiting for the milling string to shear the mud unassisted.

This patent pending method is easily configurable to suit any flow rate and viscosity and can also be rapidly removed when the mud is ready for use.

The Smart Choice:

  • Costs and time saved as shearing is boosted – In one particular application it was shown to save 12 hours of rig time.
  • Simple and quick to install and remove as the small sub requires no additional equipment.
  • Multiple choke and nozzle size options.
