CONNECTOR INSTALLATION AND REDRESS
STEP 1
ENSURE THAT THE COIL TUBING WHIP END IS FREE OF BURRS AND FLARED ENDS. ALSO IT IS ADVISABLE TO LIGHTLY BUFF SEAL AREA (APPROX THE LAST 12 INCHES OF PIPE) TO ENSURE A PROPER SEAL ACROSS THE O-RINGS.
STEP 2
REMOVE THE TOP SUB FROM THE BOTTOM SUB AND REMOVE THE RING AND SLIP FROM THE TOP SUB. IT MAY BE
NECCESARY TO TAP THE BOX END OF THE TOP SUB ON A PIECE OF WOOD SHARPLY TO JAR THE SLIP OUT.
STEP 3
BACK OUT ALL SET SCREWS ENOUGH TO ALLOW PIPE TO BE INSTALLED INTO THE BOTTOM SUB AND MAKE
CONTACT WITH THE INTERNAL SHOULDER INSIDE THE TOOL.
STEP 4
PLACE THE TOP SUB OVER THE COIL ABOUT 25-20 INCHES OR SO AND TIGHTEN 1 SET SCREW TO HOLD IT IN PLACE.
PLACE SLIP ON PIPE SMALL END UP A FEW INCHES PAST CLEAR THEN FOLLOW WITH THE BRASS RING.
STEP 5
WITH THE PIN CONNECTION END DOWN, BRING THE BOTTOM SUB UP TO THE RING AND LIGHTLY TAP UNTIL THE
END OF THE PIPE HAS SHOULDERED INSIDE THE BOTTOM SUB ID. THE RING AND SLIP SHOULD ALSO MOVE UP WITH
THE BOTTOM SUB NOTE: THE PIPE MUST SHOULDER PAST THE ORINGS IN ORDER TO SEAL. AT THIS POINT THE SLIP IS
POSITIONED EXACTLY WHERE IT WILL BE ON THE PIPE.
STEP 6
LOOSEN THE SET SCREW OF THE TOP SUB AND ALLOW IT TO FALL DOWN OVER THE SLIP AND RING. BEGIN TO MAKE
UP TOP AND BOTTOM SUB UNTIL TIGHT.
Throughout this mill out the UJT will change between milling mode and jetting mode several times on its own. The UJT will shift to milling mode when the bit sees approximately 160 lbs of resistance and will then send the flow through the bit. When the resistance mills off, the UJT will switch back to jet mode and this will happen several times with each plug. Depending on the type of plugs it should only take 3-5 minutes to compromise. After the plug is compromised and begins moving down-hole the stump will travel down until it normally reaches sand or perforations. The difference here is the stump in being "vacuumed" to the bit instead of being "jetted" down-hole. Depending on the type of plugs, milling the stump should only take a few minutes as well. Once the stump has been milled up and you were able to run in hole the UJT will stay in jet mode.
Monitoring: When running in the hole between the plugs, monitor only the differential pressure on the motor. If there is a minimal differential or none, increase the run-in hole speed and keep pushing as there is no longer any plug debris in front of the bit. Continue to do this until you are at the maximum running speed allowed by the customer.
The difference of running in the hole with only the agitator versus the UJT, with an agitator is the UJT will force the stump of the plug to be dealt with immediately and there will be nothing in front of the mill other than residual frac sand until the next plug is reached. This means no pieces of plug debris.
