United States Patent KICK SHOE FOR WASH PIPE Jack H. Marsee, Odessa, Tex., assignor to Phillips Petroleum Company, a corporation of Delaware Application June 18, 1956, Serial No. 591,893

3 Claims. (Cl. 1645-103) This invention relates to a kick shoe for deep well fishing jobs. In one aspect it relates to a kick shoe for positioning the lower end of a fishing tool in a deep well so as to contact properly ra detached piece of drill tubing or well casing. In another aspect it relates to a kick shoe for use with wash pipe for engaging detached pipe positioned off center in a deep well.

An object of my invention is to provide a kick shoe for use in conjunction with `a string of wash pipe for recovery of a piece Iof detached pipe in a deep well.

Another object of my invention is to provide a kick shoe for use in conjunction with a string of fishing tools for recovery of a section of detached pipe ina deep well.

Still another object of my invention is to provide `a kick shoe for use in slipping a string of fishing tools over the upper end of a piece of detached pipe which has fallen over to the side of a well bore.

Yet another object of my invention is to provide such a kick shoe which can be positioned in various locations in a well bore by hydraulic pressure.

Yet other objects and advantages of my invention will be yapparent upon reading the following description which, taken with the attached drawing, forms a part of the specification.

In the drawing,

Figure 1 illustrates diagrammatically the aparatus of my invention disposed in a deep well.

Figure 2 illustrates diagramm'atically va form of kick shoe of my invention as being lowered over the upper end of a piece of detached pipe in a well.

Figure 3 illustrates diagrammatically and partly in sec- Ition a kick shoe of my invention completely disposed over the upper end of ra. piece of detached pipe in a well.

Figure 4 illustrates a kick shoe of my invention in conjunction with Ea washover pipe in a well.

When -a section of detached drill pipe or casing has fallen over to one side of a well bore, prior art has disclosed use of a wall hook or knuckle joint with other appropirate fishing tools to engage and pull the detached pipe from the well. One tool of this class, designed for use with rotary tools, is deliected to one side of the well `bore by a cylinder Iand piston arrangement actuated by hydraulic pressure. When the string of tools is rotated slowly the tool engages the pipe and draws it back to the center of the well. One type of hydraulic wall hook is equipped with slips which grip the pipe after it 'has been centered in the well bore so that it can be lifted to the surface with the fishing string. Eccentric sockets and grabs are lalso available for off-center fishing operations. Although the above-mentioned prior art tools are useful under certain conditions, they do not provide means to engage a piece of detached pipe with or without a string of washover tools since conventional knuckle joints or eccentric tools cannot be used for washover jobs.

The present invention relates to a kick shoe for use with a string of fishing tools ladapted for washover purposes to allow the lower end of the kick shoe to be deected to engage the end of an olf-center pipe. My inr2,884,068 Patented Apr. 28, 1959 'ice into the kick shoe and leaves the kick shoe as a horizontal jet and defiects the shoe and the lower end of the fishing tools to the side of the well opposite the jet.

Specifically, my invention relates to a kick shoe for use with a string of tubular members in adeep well comprising, in combination, a tubular body member,

means for attaching one end thereof to said string of tubular members, a plug disposed in said body member, means for holding said plug in said body member, and an opening in the wall of said body member intermediate said plug and said one end of said body member.

My invention further comprises a method for positioning a first tubular member over the upper end of a second 'fand detached tubular member positioned ofi-center in la well bore comprising jetting fluid from said first tubular member toward the wall of said well bore opposite said upper end of said second 'and detached tubular member thereby moving said first tubular member toward the' wall of said well bore adjacent said upper end of said second and detached tubular member and lowering said first tubular member over said upper end of said second and detached tubular member.

Referring to the drawing and specifically to Figure 1, reference numeral 11 identifies a well bore in the bottom of which is shown a piece of pipe 14 which it is desired to recover. This pipe is illustrated with its upper end in a washed out portion of the well bore and thus in ofcenter position with respect to the well bore. A string of fishing tools 12 is provided with a kick shoe 13 of my invention. The above ground service equipment for such Ian operation includes a derrick 24, draw works 25, rotary table 26, and a mud tank 27a. The well bore, as illustrated in Figure 1, is provided with a conventional surface casing 20.

In Figure 2 is illustrated the kick shoe 13 being defiected by the jet laction of a jet of drilling fluid 27 emerging from an opening 15. Bolts 19 are illustrated in Figures 2 and 3 for rigidly holding a pair of rings 18 between which is positioned a blanking plug 17. The opening 15 is disposed in the wall of the tubular body of the kick shoe 13 at some position above the blanking plug 17. The lower end of this tubular 'body is provided with a serrated edge or teeth 16. Teeth 16, as illustrated in Figures 2 and 3, are substantially wedge shape. These teeth 16 are designed so as to operate as cutting edges when the kick shoe is rotated in a clockwise directio into the lower end of the kick shoe the string of toolsy and kick shoe are rotated so that the upper end of the loose pipe will wear through the blanking pluganddrilling fluid will then flow downward and around the,

section of loose pipe. Under the conditions that the loose pipe is standing free in the bottom of the Well, the kick shoe is merely lowered a suicient distance over the loose a,sse,oss

pipe so that conventional iishing tools above the kick shoe can engage the pipe.` for withdrawal from the well.

However, in case the lost pipe is frozen in the well by settled well cuttings, the fishing string and kick shoe are rotated while being lowered downward around the frozen pipe. At the same time drilling fluid under pressure is pumped down the string of tools, and this drilling uid upon emerging from an annulus lbetween the pipe 14 and kick shoe entrains the drill cuttings to carry them upward in the annulus 28 between the walls of the well and the fishing tools for their removal from the well. When the rotating kick shoe has reached the bottom of the well bore and the well cuttings have been thus removed, the pipe is free.

In one operation when using the kick shoe of my invention, a 3i-inch thick plywood blanking plug held in place in a 7-inch O.D. washpipe shoe by l-inch thick magnesium rings having an inside diameter of 5 inches and an outside diameter of 6% inches was employed. Each ring was in turn held in place with three 1/z-inch brass bolts. With a pressure drop of slightly less than 400 pounds per square inch, the kick shoe and lower end of the string of iishing tools were properly delieeted and lowered over the top end of the loose pipe. After the kick shoe was lowered over the loose pipe, twenty minutes of time were required for rotation of the kick shoe in order to destroy the blanking plug and retaining rings. In this particular case about 8,000 pounds of weight were placed on the string of tools during rotation thereof. The retaining rings 13 can also be made of plywood or other suitable material if desired. When made of plywood, they should be suiciently thick as to accommodate properly bolts 19.

The depth of the top end of the lost piece of pipe usually is known and it is possible then to determine when the lower end of the kick shoe is nearing the upper end of the lost pipe. ln using my kick shoe, it is lowered down the well until it approaches the upper end of the lost pipe and then the drilling fluid is pumped at the appropriate pressure into the fishing tools and fluid emerges through opening 15 and by its jet action moves the kick shoe in a direction opposite that of the jet. If the kick shoe is properly positioned with respect 4to the top of the lost pipe, it is then merely necessary to lower the string of tools and the kick shoe passes over the end of the pipe. A weight gauge is, of course, employed to determine by a decrease in the reading on the weight gauge when the blanking plug rests on the top end of the loose pipe. If the kick shoe has not been properly positioned over thel lost pipe in the well by the jet of uid, upon lowering the string of tools the lower end of the kick shoe may entirely miss the lost pipe; and in this case the string of tools can be lowered without observing a decrease in weight gauge reading. In this case the string of tools is merely elevated a proper distance and the string of tools is rotated, for example, about 90 and the operation repeated. Upon jetting drilling fluid from opening 15, the end of the kick shoe is swung to a side of the well bore 90 from that reached in the previous operation, and the string of tools is again lowered. If proper contact is again not achieved, the operation is repeated until upon lowering the kick shoe it surrounds the upper end of the lost pipe. In an attempted lowering of the kick shoe over the lost pipe, the lower and serrated edge of the shoe may come to rest on the top of the lost pipe and the weight gauge will show a weight decrease without the string of tools having been lowered a distance at least equal to the' distance between the serrated end of the shoer and the blankingv plug. AIn this case the string is` raised and rotated at least a small fraction of a turn and lowered in another attempt. When the shoe is properly positioned over the loose pipe the tool rotating operation isfthen started to destroy the blanking plug and retaining rings so that the string of tools can be lowered the proper distance for engaging the piece of loose pipe. If the pipe is frozen, as mentioned above, by settled well cuttings, the

cuttings are removed by rotating the string of iishing tools and the serrated edgeV or teeth 16 of Figure 2 loosen the cuttings which are then removed from the well by the mud flowing upward through the annulus between the tubing 12 and the walls of the well 11. When the pipe 14 is loosened, the pipe engaging members of the shing tools then engage the pipe and the pipe is withdrawn from the well.

While in the drawing I have illustrated a single open- 15 for the ietting of drilling iluid, it is obvious that more than one opening for this jetting action can be employed. For example, if a pair of openings disposed about 30 to 45 apart around the circumference of the kickk shoe, a more nearly positive directional movement of the kick shoe is achieved.

The bolts 19 are, if desired, made of brass or other easily destructable matenial so that the bolts also will be destroyed at the same time the blanking plug and holding rings are destroyed. While I have illustrated in the drawings and described the blanking plug as being held in position by a pair of rings, any other suitable holding means can be employed; for example, bolts similar to bolts 19 can be threaded directly into the blanking plug. In this latter case the blanking plug should iit the tubular body of the kick shoe in a reasonably huid-tight manner. It is not essential that the blanking plug and holding rings or other holding means be strictly uid tight, but leakage between these members and the body of the kick shoe should should obviously be held at a minimum.

Although l have illustrated threads 22 as being a means for attaching my kick shoe apparatus to the bottom end of the lishing tools and/ or wash pipe, other suitable means of attaching can be employed.

The serrated kick shoe apparatus in my invention has particular application in freeing lost pipe in a well which is locked or held lin a key seat. After properly positioning the lower end of the kick shoe over the upper end of. a stuck pipe and on lowering the string of tools While rotating, the key seat, that is, the portion of the uncased walls of the well which holds the pipe is ground away. After grinding away the key seat, the pipe is then freed and is lngaged by the iishing tools for withdrawal from the we In Figure 4 is illustrated the kick shoe 13 of my invention attached to a washover pipe 31 on the end of tubing 30 and positioned in well bore 11. The operation of the kick shoe with the washover pipe is substantially the same as hereinbefore described in relation to fishing tools 12 of Figure l. Fluid jetted from opening 15 moves the washover pipe 31 oft center of the well for lowering over the upper end of pipe 14. The washover pipe 31, tubing 30 and the kick shoe are rotated by the same aboveground apparatus as illustrated in Figure l to grind away the blanking plug 17 (Figure 3) so this rotating apparatus can be lowered around pipe la. After pipe 14 is loosened or substantially loosened, fishing tools are lowered inside tubing 30 or the tubing 30, washover pipe 31 and kick shoe 13 are removed from the well, and fishing tools used for removing pipe 1d.

While certain embodiments of the invention have been described for illustrative purposes, the invention is not obviously limited thereto.
