Definitions
- the field of this invention relates to downhole completion techniques involving insertion of liners or tubulars and tying them to existing tubulars without reduction of internal well dimension, generally using the technique of expansion.
- a method of attaching a tubular to an existing tubular in a well without reducing the inside diameter of the well is described.
- a shoe is attached to the lower end of the existing lowermost casing or tubular, generally prior to the casing being cemented or otherwise secured in the wellbore.
- the shoe has a diameter larger than the inside diameter of the casing or tubular to which it is attached.
- a liner is run in until its top end is in the enlarged diameter region of the shoe.
- a hanger can be optionally used.
- the liner is expanded into the enlarged diameter so that the net result is that the inside diameter in the wellbore is not reduced by the addition of the liner.
- Figures la-lc the method with a shoe having an enlarged inside diameter
- Figures 2a-c illustrate the method with an expandable shoe
- Figures 3a-3c illustrate the method with a pre-crushed shoe
- Figures 4a-4b illustrate the method with a special profile shoe
- Figures 5a-5b illustrate the method with a memory metal shoe
- Figures 6a-6b illustrate the method with a soft material filled shoe
- Figures 7a-7b illustrate the method with a covered recess shoe
- Figures 8a-8b illustrate the method with a machined shoe.
- casing is intended to encompass all manner of tubulars found in a wellbore, whether cemented or otherwise secured.
- the casing 10 has an inside diameter 12.
- a shoe 14 is attached at lower end 16.
- Shoe 14 has a diameter 18 that is larger than inside diameter 12.
- the wall thickness 20 of a tubular 22 will, when expanded against diameter 18 will not create an internal dimension below shoe 14 that is smaller than diameter 12.
- the recess in shoe 14 defined by diameter 18 being larger than diameter 12 allows accommodation of the wall thickness 20 of the tubular 22, after expansion into contact with shoe 14 to avoid well constriction.
- the casing 10 has most likely been previously cemented or otherwise fixated limiting its ability to further expand appreciably without application of excessive amounts of force.
- the shoe 14 is not limited in the same manner as the casing and can expand with the tubular 22.
- the casing 10 may itself be fixated by expansion along with shoe 14.
- the tubular 22 is delivered on a running string in combination with a known swage and expansion into diameter 18 takes place until the tubular 22 is secured.
- the swage is removed with the running string (not shown) in a known manner.
- shoulder 24 is deep enough to accept the wall thickness 20 with no part of it, after fixation extending beyond so as to reduce the diameter 12 of casing 10.
- Figures la-lc show schematically the insertion of the casing 10 with the shoe 14.
- the tubular 22 is lowered into position. It may optionally have known seals and/or a liner hanger (not shown) attached near upper end 26.
- Figure lc shows the tubular 22 in position and ready for attachment to shoe 14, preferably by a known expansion technique.
- Figures 2a-2c show a shoe 19 on casing 10 where the internal diameter 21 of shoe 19 is nearly the same as the diameter 12.
- a known expansion device 23 can create a diameter 25 larger than diameter 21.
- the tubular 22 can be expanded or otherwise attached to diameter 25.
- the tubular 22 can also be delivered prior to expansion of diameter 21 so that the shoe 19 and the tubular 22 are both expanded together in a single step, as opposed to the two steps required in the illustrations of Figures 2a-2c
- Figures 3a-3c illustrate a crushed shoe 28 that has a reduced end diameter to facilitate running in the casing 10.
- an expansion tool 30 reforms the shoe 28 so that it has the enlarged diameter 18.
- the tubular 22 can be expanded into recess 24 without intruding into the diameter 12 of the casing 10.
- seals and/or hangers can be used on tubular 22 and expanded or otherwise set into enlarged diameter 18.
- Figures 4a-4b show a shoe 32 with a series of projections 34 and alternating valleys 35. This can be a thread pattern or some other kind of pattern or a random distribution of peaks and valleys.
- Figure 4b shows that after expansion with a known tool 30, the peaks 34 become valleys 36 on the inside while on the outside what have previously been a valley 35 become external peaks 38.
- the external peaks 38 help to fixate the shoe 32 in the wellbore.
- the diameter defined by internal peaks 40 is preferably more than diameter 12.
- the tubular 22 could be subsequently introduced and expanded against peaks 40 for gripping contact.
- the tubular 22 could also be expanded at the same time as the shoe 32 is initially expanded for a single trip operation.
- Figures 5a-5b illustrate a shoe 42 made from a well-known memory material.
- a memory material responds to electrical, acoustical or thermal inputs from a tool 44 to change shape to create the enlarged diameter zone 46.
- the tubular 22 can be expanded into zone 46 to secure it without reducing the diameter 12 above.
- seals and/or a hanger can be used in conjunction with an expansion technique with a swage or some other method of mechanical fixation can be used if the end result is that the diameter 12 is at least as large as the internal diameter of the tubular 22 after it becomes supported.
- the shape change and the fixation of tubular 22 can also occur in a single trip.
- Figures 6a-6b illustrate a shoe 48 with a recess 50 so that it has a larger diameter 52 than diameter 12.
- the recess 50 is initially filled with a soft material 54 that is compatible with well pressures, temperatures and fluids. It could be aluminum, lead, a composite, foam, plastic or any other material that will be easily displaced during drilling, expansion or fixation of the tubular 22.
- the material 54 protects the large diameter 52 until the tubular 22 is in position and is expanded, as shown in Figure 6b. Some or all of the material 54 may be displaced during the expansion or fixation. In the end, the inside diameter 56 is close to or greater than diameter 12.
- Figures 7a-7b illustrate a shoe 58 with a sleeve 60 in a recess 62.
- the sleeve 60 can be removed by a variety of techniques. It can be physically displaced, chemically dissolved or attacked, thermally attacked or any other technique that will get it out of the way to expose the larger diameter 64 that is defined by recess 62.
- the tubular 22 can be fixed such as by expansion, in larger diameter 64 with the result as described before that there is little if any reduction in the internal diameter 12 going further downhole.
- the tubular 22 can remove the sleeve 60 as it is lowered into position.
- Figures 8a-8b show a shoe 66 that is attached to the casing 10 and machined or otherwise has its internal dimension increased after it is positioned in the wellbore.
- a mill or reaming tool 68 can be used to create a larger diameter 70 than diameter 12.
- a mill or reaming tool 68 can be used to create a larger diameter 70 than diameter 12.
- the various illustrated embodiments of the method of the present invention allow the attachment of a tubular to casing where after the conclusion of the attachment, the diameter of the tubular is close to the internal diameter of the casing above and even greater. Contrasted to prior techniques that overlapped the tubular with the casing and resulted in a decrease in internal diameter in the order of the thickness of the wall of the tubular, the present invention gives a simple way to overcome this problem and allow for minimal or no reduction in internal diameter and even an increase in the internal diameter. Currently the technique in Figures 1-lc is preferred.
