m. Release the hoist line from the sling of the lifting bale assembly and attach the hoist
line to the top shackle of J-latch assembly. If the shackle is damaged or missing the rope
socket may be used attached to the rigs slickline Insure the proper amount of spacer bars
between the J-latch and the shackle assembly, to lower the tool to the Mule Shoe.
n. Attach the J-latch onto the pins of the spear-point of the MWD tool and secure the pins
in the J-latch by pushing down and turning the J-latch counter-clockwise.
o. Direct the hoist operators to slowly lift the tool assembly connected to the J-latch and
lift the tool about one foot and remove the lifting bale assembly. Be acutely aware of
possible pinch-points and keep hands and fingers clear!
p. Contact the Directional Supervisor to witness the next operation. This is a requirement!
Instruct the hoist operator to gently lower the tool down into the collar until the tool
contacts the Muleshoe sleeve. DO NOT run the tool in hard! Severe contact of the point
of the helix to the Muleshoe Key can damage one or the other or both. CLOSELY
observe the tool for rotation as it enters the Muleshoe sleeve and seats. Have the hoist
operator gently lift the tool up approximately 3 feet and rotate the tool 180 degrees
counter-clockwise then slowly lower the MWD tool assembly back into the Muleshoe
sleeve. Again, CLOSELY observe the tool for rotation as it enters the Muleshoe sleeve.
With a pipe wrench, grip the spacer bar and attempt to rotate the tool, clockwise looking
down hole. A strong resistance to turn will indicate that the tool is seated. The MWD
operator and the Directional Supervisor MUST observe the tool‘s rotation before
proceeding.
q. Disconnect the J-latch from the spear point by pushing down on the spacer bar and
lifting the assembly off the tool.
r. Pickup the lifting and seating tools and clean them completely and place them back in
the kit box. Keep them clean and free from rust by painting them.
