A discussion on the various fishing tools now available and how they are used. OUTLINE CABLE TOOL HISTORY JOB SITE SAFETY CABLE TOOL BASICS CABLE TYPES API TOOL JOINTS FISHING TOOLS & TERMS FISHING JOB AT PIIC #4 CABLE TOOL HISTORY History Since man first drilled wells on earth, he has faced the problem of obtaining water to survive. Ancient drillers must have realized the need for special drilling tools with which to extract obtain this water. Chinese and Persians constructed wells as early as 2000 B.C. by the percussion drilling method. History History ONE OF THE FIRST WELLS DRILLED IN THE UNITED STATES WAS IN 1807 IN BUFFALO LICK, WEST VIRGINIA BY DAVID & JOE RUFFNER. History TOOL STRING MADE UP BY A LOCAL BLACKSMITH, CONSISTING OF JOINTED IRON RODS AND A CHISEL BIT. WELL COMPLETED IN 1808 TO A DEPTH OF 58FT. History SPRING POLES ALLOWED THEM TO DRILL DEEPER BUT FISHING FOR BROKEN TOOLS BECAME THE NORM. History 1830 HORSE POWERED RIGS GAVE WAY TO THE STEAM ENGINE AND STANDARD 4-LEGGED DERRICKS History 1831 BILLY MORRIS INVENTED JARS TWO TYPES ENDLESS - SPANGE WELDED THE NEXT 50 YEARS FREE-FALLING JOINTED STEEL RODS WERE DEVELOPED. History 1867 Henry Kelly invented the portable drill rig that revolutionized the water well drilling industry. First rig built in small shop near Osage Iowa 1891 Henry Kelly became associated with O.B. Tanneyhill selling rigs under company name of Morgan, Kelly, and Tanneyhill. EARLY PROBLEMS/FISHING DRILL STRING MADE OF WOOD BREAKAGE WAS COMMON WEAR WAS FAST DEPTH DETERMINED BY FLOATING TOOLS WHICH ALSO SLOWED DOWN THE DRILL. German grabs hooks 1850 German fishing tools of 1886 EARLY PROBLEMS/FISHING PROBLEMS OF UNCREWING W/STRAIGHT THREAD USE OF STEEL CABLE VS HEMP ROPE STEEL DERICKS VS WOODEN DERICKS USE OF CRACKER History DRILL TOOLS JOINTS WERE ORIGINALLY MADE WITH A STRAIGHT THREAD A PRACTICE WHICH CAUSED THESE JOINTS TO TAPER FROM LONG, CONTINUED USE. DISCOVERED THAT A TAPERED JOINT MADE A MUCH STRONGER, SECURE CONNECTION. DRASTICALLY REDUCED FISHING. “CRACKER” History SINCE DERRICKS WERE ALL STIFF LEGGED, SOMETHING HAD TO BE MADE FOR ABSORBING THE SHOCK OF THE DRILL TOOLS ACCOMPLISHED BY USING A 25 – 50FT LENGTH OF MANILA LINE BETWEEN THE TOOLS AND STEEL CABLE. CALLED THE “CRACKER” History ED RENNER’S FIRST SINGLE CYLINDER ENGINE DRIVEN CYCLONE WOODEN MAST, HEMP ROPE, PITMAN ARM {EARLY 1900’S} History 1904 Kelly died, name changed to Armstrong-Quam Co. 1910 name again changed to Armstrong Manufacturing Company.

Selection Wire rope as we know it today appeared in the U.S. about 1830 but did not develop until after the Civil War ended in 1865. Accelerated the drilling process. Reduced friction & provided longer life. Selection Measurement How to measure wire rope diameter The correct diameter of a wire rope is the diameter of a circumscribed circle which will enclose all the strands. The measurement should be made carefully with calipers. Illustrations above show correct and incorrect method of measuring the diameter of wire rope. Selection True diameter allows you to determine the wear on the cable. Flat, crushed, or broken strands Selection Selection Selection Cable tool line TYPES OF CABLE TOOL LINE Drill line Bailer line Casing line Slings Guy Lines Cable tool line DRILL LINE IS 6x19 Left Lay - Regular Lay Classification: Each strand has 9 outer wires over 9 smaller inner wires over one large center wire. Good rope to withstand abrasion or crushing on the drum. Cable tool line BAILER LINE IS 6x7 Right Lay Regular Lay Classification: Each strand has 6 wires over one large center wire. Good rope to withstand abrasion or crushing on the drum. Cable tool line CASING LINE IS 18x7 Right Lay Regular Lay Classification: Eighteen strands with 6 wires over one large center wire. Good rope to withstand abrasion or crushing on the drum. Cable tool rope {Contra-helically laid} ropes are designed with opposing rotational forces. Achieved by laying six strands around a core strand in one direction and then laying 12 strands around the first operation in the opposite direction. Cable tool Rope The word Lay means: Direction Right/left Relationship Regular/Lang Length One Rope Lay Cable tool Rope Drill line Bailing Line Left Lay Regular Rotate Right Lay Regular Rotate Hoist line Right Lay Regular Non-Rotate Cable tool Rope REGULAR LAY Wires are laid opposite the direction the strands lay in the rope Cable tool Rope LANG LAY The wires are laid in the same direction as the strands lay in the ropes Cable tool Rope Cable tool Rope SEVEN FEATURES OF CABLE Strength Reserve strength Resistance to deformation Crushing resistance Bend-ability Stability Cable tool Rope BENDING STRESS All ropes operating over sheaves or drums are subject to bending stress. The degree of fatigue partially depends upon the ration of the diameter of the rope to the diameter of the sheave or drum. Other factors affecting the fatigue life of the rope are load, number of cycles and condition of the sheaves and drums. Cable tool Rope CORRECT WRONG Cable tool Rope Proper way to spool bailer line and Casing line. Cable tool Rope Proper way to spool Drill line. Over wind from right to left. Cable tool Rope Proper spooling ensures cable is installed without damage. Damaged cable ensures failure of the cable and a fishing job. SPOOLING THE BULL REEL SPOOLING THE SAND REEL SPOOLING THE CASING LINE Cable tool Rope Bucyrus Erie 36-L cable change using a chain and sprockets. Replace cable as often as necessary. Cable tool Rope Chain driven spooling techniques make cable changes easy. Cable tool Rope Can be used to install and remove cable from rig. Cable tool Rope Good Maintenance practices: Break in new rope Reversing ends Constructional stretch Lead in new socket every 2 weeks Clean & lubricate regularly Cable Care Clean and lubricate regularly to reduce wear. Inspect for dirt, rusty conditions, breaks & cracks Cable Care 65% of all fishing jobs are cable breaks due to: Poor Maintenance Lack of inspections Fatigue, cracking, splintering Periodic rope socket changes Break in period Double shifting rig. Cable Wear Cable fatigue normally appears at locations of the crown sheave. Cable Wear Cable splintering is a fatigue resulting from heavy loads over small sheaves. Again, normally found in the crown and sometimes found tool late.

BUTTON SAVER Curvature is 25-degrees same as mandrel & socket RINGS Joint rings of .010” in thickness 4” x 5” joint and 4-1/4” x 6” joint Make up for joint wear 36” STAR BIT Tool joints can break at the box square Two principal factors responsible for the greatest percentage of fishing problems 1. Abuse of tools and continued use of them after they have become worn beyond point of safety. 2. Lack of respect for the dangers involved in well drilling, poor judgment and operational procedures. An experienced driller can: Grasp the cable and ascertain every condition of the hole. Bit Blows. Tools are turning. Change of formation Falling ledges Hole collapsing Cable breakage Tools are sticky 60-L Paul Strom Building 1956 JOB SITE SAFETY – ANTISIPATING THE UNEXPECTED. FOCUSED AND ATTENTIVE A Prudent driller avoids trouble by constant watchfulness and careful maintenance of equipment. Perform your job like you fingers depended on it. A FISHING STRING IS MADE UP OF: ROPE SOCKET SHORT STEM FISHING JARS FISHING TOOL FISHING TOOLS STRING Socket (non swivel) Bar Fishing Jars Fishing tool ROPE SOCKET Desirable for a “stiff neck” or Babcock or burns type rope socket. Do not want the tools to spin in the hole while fishing. Insert a small piece of wood in the swivel to prevent turning. Burns socket swivel Fishing Stem Fishing Stem Desirable for a drill stem not to exceed 10ft. Fishing jars Identical to regular jars except for the length of rein opening, or stroke. Some Spudding gears have various holes for longer strokes. Necessary for a complete revolving stroke cycle of the rig to assure jar action in one direction only—either up or down, but never both. FISHING TOOLS Fishing Tools A. B. C. D. E. F. G. H. Horn Socket Corrugated Friction Socket Rope Spear or Rope Grab Latch Jack Wall Hook Alligator Grab Jar bumper Crows (Cows) foot Fishing Tools I. Down Cutting Wire Rope Knife. J. Combination Socket Regular pattern slip socket Full circle fishing socket Combination slip socket K. Slip collar Socket L. Jar Socket M. Spud - regular type Horn Socket Long taper steel barrel, slotted on one side Mouth passes over top of lost tools. Cable let out to allow jars to close. Spud horn over top of lost tools with only a few blows. Straight hoist pull will bring lost tools to the surface. Drive wedge in slot to release horn on fish. CORRUGATED FRICTION SOCKET Spiral impressions formed on steel barrel & fitted with a pin joint with a slight bell bottom. Long bar, heavy stroke on jars Drive down over bar Permits a limited amount of upward jarring. Rope Spear or Rope Grab Tapered prong on which “wickers” are welded. Send down hole where large amounts of cable are lost on top of the tools Fitted with standard pin and wrench square. Two prong grab Three Prong Grab Never drive down on a spear or rope grab when the tools are stuck in the hole. Suggest dropping soft coal into the hole. A handful per inch of hole. Aid in keeping the cable separated. Directions on use of Grab/Spear Spear or grab should be lowered on the fishing string until it reaches the cable. Engage the spudding gear and lower fishing string slowly to allow the wickers to pick up the cable. When you think you have enough knotted cable, stop the spudding action, and lift out the tools. Avoid jerking or spudding up. When the spear or grab appears at the surface, stop and wrap the cable up with wire to prevent unraveling. Hoist high enough to grab tools with wrench square. Care not to get tangled up in cable if you drop them. Latch Jack i i " . Used for fishing out bailers I I Lower latch jack until contact is made. Latch will open & close over bail. Hoist string out slowly Some light upward jarring is ok. Hard to get off fish if bailer is stuck. Bailer reins, throats, & crowns. Outside latch Sand bottom. Wall Hook A wall hook is used to hook a lost bit or to straighten a string of tools out of a cave and back into the center of the hole for recovery. Since the cable is left lay, order out a left hand curvature. Alligator Grab Useful in recovering small objects. Jaw tension can be increased by adjusting the spring above jaw cage. Jaws held open by a trip pin on bottom. Jaws close when contract is made. Run on a full string of fishing tools, Socket, bar, jars, grab. Jar Bumper Three Types: Solid eye Swivel eye Solid Jar Bumper Used to free stuck tools when jars are not used. Jar bumper is put in place of the bailer. Cable is placed in slot. Strain on stuck tools, drop bumper 10-15ft onto top of rope socket. If tools are not from in 15 minutes, remove bumper for inspection. Crows Foot Used to de-burr the top of the rope socket that is deformed or curled from bumping. The burrs prevent a secure catch by the combination slip socket. Size is determined by the hole size & tools size. Avoid driving tool into side wall. Exact measurements of location must be known. Down wire cutting rope knife Either Down or Up wire cutting rope knife is available. Used to cut cable on tools stuck in hole to permit grab via combination socket. Blade located in body connected to a small set of jars. Swivel eye at top connected to sand line. Face plate removal allows positioning over drill line. Down wire cutting rope knife Before assembly is lowered, light tension is placed on drill cable. Permits the body to slide freely along the drill cable. Assures the operator that no cutting can be done until the body contacts the rope socket Lowered slowly until contact with the rope socket. 2-3 blows will cut cleanly. Combination Sockets Three types of slip sockets: 1> Regular pattern slip socket 2> Full Circle fishing socket 3> Combination slip socket Regular pattern slip socket Designed for ordinary fishing jobs where hard or continual jarring is not required. Two spoon shaped slips that work inside a tapered barrel. Bowl thickness determines the max diameter it will catch with thin slips. Regular pattern slip socket Full Circle fishing Socket Due to the full circle support, this socket will stand severe jarring and not oblong the bowl. Provides a much firmer hold on the collars of lost tools. Can be used for retrieval of sockets, bars, jars, or bits. Full Circle fishing Socket 4-slips mounted on two reins to form a complete circle. Attached by a bolt that allows the slip to ride up as the fish enters and falls down to trap the string. Full Circle fishing Socket Large diameter joints are 3-1/4” x 4-1/4” Combination Slip Socket 3-slips form a circle inside a tapered bowl. Held in place by a strong compression ring. Designed to catch rope sockets necks, thread pins, or box collar diameters. Combination Slip Socket Collar Sockets Exact diameter of fish must be known. Driven gently over lost tool. Each slip is smaller than the lower one. Hitch is secured, pull up 10-15ft & swing tools before removal No heavy jarring Jar Sockets Designed to fish for broken jars. Two types available Side Jar Socket where only one rein is looking up. Center Jar Socket where both reins are looking up. Rather weak and difficult to run. Not recommended to run unless absolutely no other fishing tool will work. Jar tongue Sockets Designed to catch broken jars when the tongue is sticking up. Used when tolerances do not allow corrugated friction socket or full circle slip sockets. Made of two patterns, solid and screw bowl. Jar tongue Sockets Run with long stroke jars run between the socket and stem. Lowered down over tongue. If secured, set back down and hit down to set the socket, and pull back up. Cannot use spudder. Jarring up with a tight hitch. Do not jar down or the hold is easily broken. Spud Composed of a long spade-like piece of high carbon steel, curved to conform to a section of the wall of the well. Equipped with a pin joint on the upper end with a square or flats. Purchased quarter, half, or three-quarter round. When ordered specify joint size, length, and round. May be purchased the length of the lost tools. Spud Used with long stroke fishing jars immediately above the spud, with a short stem and a stiff wire line socket. Operate in slow motion to allow jars to strike both ways. Once materials are churned up, bailer used to clean out the results of each run. Drive pipe over the lost tools. Repeat until the top of the lost tools to allow contact hold with the fishing socket. KEY TO SUCCESSFUL FISHING EVALUATE THE HOLE STABILITY. SAND FILL UP INSIDE THE CASING OR OPEN HOLE THAT IS ALSO AROUND THE TOOLS (FISH). DRILLING FLUID CONDITION LOST CIRCULATION LEDGES KEY TO SUCCESSFUL FISHING NEVER PUT ANTHING IN THE HOLE YOU DON’T THINK YOU WILL GET BACK. CAN YOU GET OFF IF YOU GET ON. KNOW THE LIMITATIONS OF THE TOOLS RECORD THE OD, ID. AND LENGTH OF THE FISHING STRING AND MAKE DRAWINGS KEY TO SUCCESSFUL FISHING PATIENCE CAREFULL EVALUATION & MEASUREMENTS USE THE RIGHT FISHING TOOLS NEVER USE QUESTIONABLE FISHING TOOLS OR EQUIPMENT DEGREE OF SUCCESS SUCCESS IS MEASURED NOT IN THE TIME IT TOOK YOU TO REMOVE LOST TOOLS IN THE HOLE BUT RATHER DID YOU GET THEM OUT.
