Abstract
THIS IS A PORTABLE UNIT DESIGNED TO PROVIDE A MACHINE PROCESS TO THE
FIELD. THIS PROCESS IS DONE WHILE THE COIL TUBING IS STILL ATTACHED TO
THE MOBILE COIL TUBING UNIT. ONCE THE UNIT IS SECURLY FASTENED TO THE
COIL TUBING THIS INVENTION PROVIDES THE ABILITY TO REMOVE THE WELDED
SEAM IN ALL SIZES OF COIL TUBING WITH A ROTATING CUTTER THAT WILL
ADJUST TO THE COIL ANGLE AND NATURAL BENDING (MEMORY) BY PIVOTING
THE CUTTER WHILE ROTATING. ALSO BEING ABLE TO POSITION CUTTER THRU
STRAIGHT LINE INSIDE THE COIL TUBING.

Description
DESCRIBE HOW YOUR IDEA "OPERATES/FUNCTIONS."
COMPONENTS ARE ASSEMBLED AS FOLLOWS:
SLIDE COIL TUBING MOUNTING SLEEVE # 1 ONTO THE COIL TUBING AND SECURE
WITH ATTACHMENT SCREWS # 6. AS BEST SEEN IN FIG 1 SLIDE CUTTER BASE ROTATING BRACKET # 2 OVER COIL TUBING MOUNTING
SLEEVE # 1 AND LINE UP ROTATION GROOVES WITH ROTATION SCREW HOLES, INSERT AND TIGHTEN (3) SCREWS #7 UNTIL THEY SHOULDER OUT LEAVING
CUTTER BASE ROTATION SLEEVE FREE TO ROTATE. INSERT THE (2) BRASS LOCK
BOLTS TO BE USED WHEN NEEDED. AS BEST SEEN IN FIG 1 ATTACH ADJUSTABLE CUTTER BUSHING #3 TO PROVIDED TANGS ON ROTATING
BRACKET.INSERT BOLTS AND NUTS - LEAVE LOOSE AS BEST SEEN IN FIG 1 ALIGHN ROTATING BRACKET PARALLEL BESIDE SEAM TO BE REMOVED
INSERT ROUND CUTTER AND STEADY BAR INTO ADJUSTABLE CUTTER BUSHING
#3 AND LAY BESIDE SEAM (APPROX 6" UP INSIDE OF COIL) AND TIGHTEN
ADJUSTABLE CUTTER BUSHING #3 WITH FLAT SCREWS. PULL CUTTER/STEADY
BAR OUT OF COIL, ROTATE SLEEVE #2 TO LINE UP CUTTER WITH SEAM. (RE -ADJUST IF NECESSARY) AS BEST SEEN IN FIG 2 ATTTACH 1/2" PORTABLE HAND DRILL TO STEADY BAR DRIVE PIN SLOWLY

DISCRIPTION OF THE INVENTION
CUSTOMER NEED. THE COIL TUBING INDUSTRY REQUIRES A LARGE VARIETY OF
TOOLS TO BE SECURELY MOUNTED TO THE END OF THE COIL. THESE
REMOVABLE TOOLS ALL REQUIRE THE ABILITY TO CONTAIN GAS AND FLUID
PRESSURE AS IT PASSES THROUGH THE TOOLING ON THE WAY DOWN HOLE. IN
ORDER TO DO THIS THE INSIDE OF THE COIL NEEDS TO HAVE A SMOOTH
SEALING FACE FOR ELASTOMER SEALS TO PRESS AGAINST. COIL TUBING
TYPICALLY HAS A WELDED SEAM LEFT OVER FROM MANUFACTURING RUNNING
THE FULL LENGTH ON THE INSIDE. THE INVENTION BEING APPLIED FOR PATENT, ADDRESSES ALL THE ISSUES INVOLVED WITH REMOVING THIS SEAM TO THE
DEPTHS THE INDUSTRY REQUIRES. THIS TOOL IS PORTABLE AND IS MOUNTED
DIRECTLY TO THE COIL TUBING IN THE FIELD UNTIL SEAM REMOVAL IS
COMPLETED. THIS TOOL IS UNIQUELY DESIGNED TO COMPENSATE FOR THE
COILS "MEMORY "OR SET AS WELL AS DEALING WITH USED COILS TENDENCY TO
BE OUT OF ROUND. THE CUTTER ACTS ON ONE SIDE ONLY (THE SIDE WHERE
THE WELD FLASHING IS) AND CAN PIVOT AND SWIVEL TO MANOEUVRE IN A
MULTITUDE OF WAYS WHILE WORKING UP INSIDE THE COIL.
1. YOU ONLY REMOVE THE SEAM

WEATHERFORD - SEAM REMOVEAL TOOL DRILLS A ROUND HOLE IN OVAL COIL
REMOVING MATERIAL FROM THE COIL WALL PLUS THE SEAM
LINMAR OIL TOOLS- PORTABLE REAMER. CUTTER MUST BE IN CONTACT ON ALL
SURFACES FOR CENTERING PURPOSES. AS A RESULT IF IT IS USED IN AN
APPLICATION WHERE THE COIL TUBING IS OUT OF ROUND OR FLATTENED ON
ONE SIDE THIS TOOL WOULD THIN OUT THE WALL IN THE UNDERSIZED AREA
RESULTING IN A SECTION OF TUBING WITH COMPROMISED STRENGTH.
CLEANING SHOE FOR PIPE- PATENT NUMBER US 6,395,098 BI. THIS TOOL
REQURIES THE PIPE TO BE ROTATED AGAINST A PASSIVE GRINDER
THE TOOL BEING REQUESTED FOR PATENTING DIFFERS FROM THE KNOWN COIL
TUBING DRESSING TOOLS IN THAT IT IS PORTABLE AND SMALL ENOUGH TO BE
FIXED TO COIL TUBING WHILE THE TUBING IS MOUNTED TO A COIL TUBING
TRUCK. THIS TOOL WITH ITS MULITI-POSITIONAL ABILITY ALLOWS CONTROL OF
WHERE AND HOW MUCH MATERIAL IS REMOVED FROM AN ALREADY THIN WALL.
THIS HELPS MAINTAIN THE INTREGITY OF THE COIL TO HOLD PRESSURE AND
ULTIMATILY MAKING FOR A SAFER ENVIORNMENT FOR THE WORKERS
SERVICING A WELL.
NOTE: THIS TOOL ELIMINATES THE DANGEREOUS PRACTICE OF GRINDING
METAL AT A DRILLING SITE AND POTENTIALLY SPARKING GAS AT A WELL HEAD..
Page 4 of 6 WHAT PROBLEMS DOES YOUR IDEA SOLVE?
= COIL WALL THICKNESS STAYS CONSTANT
= ONLY SEAM IS REMOVED
= CAN CUT SEAM OUT OF ANY SIZE OF COIL
= OVALITY OF COIL WILL NOT EFFECT CUTTER OF FUNCTION
WHAT BENEFITS WOULD USERS RECEIVE?
= ALLOWS FOR INTERNAL SEALING FOR TIGHT WELLS
= SEAM CAN BE CUT OUT OF ANY SIZE OF COIL
= SAVES TIME
= RELIABLE
= FAST
= KEEPS THE INTIGRITY OF THE COIL
