Casing and Pipe cutting equipment

 Single-Trip Casing Cutting System was designed to speed up and simplify the mechanical abandonment operation. It removes the need for the old fashioned marine swivel and the heavy, rigid and hard to handle drill collar string. The system speeds up the handling of the cutting string as only one stand of 8" drill collars need to be run above the cutting assembly.
q pipe cuters range in size from 3 5⁄8" OD to 16" OD and will cut 4 ½" to 36" casing. The pipe cutter works on the principle of pressure drop across an orifice, which in turn forces the cutting blades into the open position. The tool is equipped with a piston position indicator which enables the operator to be positive that a cut has been achieved.

Drilling Components Oscillator

generate radial
vibration used to reduce friction between the drill string  and the formation.
These vibrations will reduce drag during sliding and reduce torque during rotary drilling operations.
ydraulically activated tool
The mud flow is distributed around the plug
The stator directs the mud flow at preadjusted angle
The flow creates pressure on the rotor and forces it to rotate at a speed of 2000 rpm
Rotor rotation is transmitted to the eccentric and causes vibration
Features and benefits
Increases ROP and helps maintain tool face orientation
Friction and radial loads reduction
BHA and Drill string torque reduction
Reduction of tool orientation time in the wellbore after pulling of bottom
Reduces buckling
Longer bit life and improved PDC bits performance
Wellbore stability increase
Horizontal wells and extended reach applications
Assists in differential sticking minimizing

Can be run as a permanent or retrievable anchor.
Allow to run anchor, whip stock and starter mill on the trip.
Can be sat on any solid bottom.
Minimizes the possibility of movement or rotation by its bi-directional slips.
Whipstock – Hydraulic Set, 5 ¾”, 6 5/8”, 7”, 9-5/8”, 13-3/8” & 20”
Hydraulic set and can be permanent or retrievable
Packer can be used as a barrier
Expandable Open or Cased Hole whip stock System

The Arm actuation does not involve cams underneath the blades – if the Arms are pulled back against a restriction, the activation force can be overcome and they are forced to close into the Body which prevents hanging up on the
Custom designed cutters maximise diamond coverage at the lead corner of the Cutter Arms. Top quality PDC inserts sourced from industry recognised suppliers. Cutter Arms are replaceable without breaking down the rest of the tool. The dynamic seals are deployed in the Top and Bottom Subs allowing quick access for replacement.
A robust body machined from solid 4145 steel forging and API external connections no parallel threads in the structural part of the tool.
Activated by Bit Pressure Drop but can be modified to suit drop-ball activation
Placement of nozzles in the arm bays ensures that they remain clear of debris which could prevent arm closure.
The SDR has an integral stabilised section immediately below the underreaming section to maintain concentricity and reduce vibration, and does not rely on stabilisers below the underreamer.
