- Fig. 1 shows a schematic illustration of an apparatus 10 in a wellbore 12 with an expandable tubular member 14 and an expansion cone assembly 16 supported by a tubular support 30 (such as a drill pipe 30), all supported by a float shoe 32 for running into a wellbore 12 through a plurality of casing sections 18a and 18b of a mono diameter wellbore casing 18 in the process of being formed, according to one aspect to the invention.
- the existing casing 18 sections 18a and 18b have been formed from expandable tubular members 14 and according to the teachings of the present invention include mono diameter portions 28a and 28b with a first inside diameter ID1 and bell portions 22a and 22b having a second inside diameter inside diameter ID2 and a length L. There is an overlapping portion 26 where the bell portions 22a overlap of the casing section 18b.
- Fig. 2 shows a schematic illustration of the expandable tubular member 14, acted upon by a large cone 20 of the expansion cone assembly 16 to expand the diameter of the lower end of the expandable tubular member 14 to form a bell portion 22.
- the bell portion 22 is formed by the large cone 20 of the expansion cone assembly 16 that has an adjustable cone diameter sufficiently large so that the resulting expanded inside diameter of the bell portion 20 is at least slightly larger than a desired inside diameter of the mono diameter wellbore casing 18.
- the length of the bell portion 20 depends upon the desired length of overlapping lengths 26 between nested casing sections 18a, 18b, and 18c.
- the overlap length 26 and therefore the bell portion 22 may have a length up to about 30.5m (100 feet) or up to about 45.7m (150 feet).
- Fig. 3 shows a schematic illustration of the expandable tubular member 14 of Fig. 2, with the expansion cone assembly 16 positioned for expanding the expandable tubular member 14 to the desired mono diameter at the portion 28 above the bell portion 22.
- the diameter of the large adjustable cone 20 is collapsed, or is other wise adjusted, to a smaller diameter.
- Another cone 24, having a diameter smaller than the large diameter of cone 20, is provided for radially expanding the tubular member 14 to the desired inside diameter of the mono diameter wellbore casing.
- the wellbore casing section 18c of the mono diameter well bore casing 18 of Figs. 1 and 2 overlaps with the wellbore casing section 18b along the overlapping length 26 and at the bell portion 22b.
- the inside diameter or the bell portion 22 and the outside diameter of the mono diameter portion 28 are the same to provide a tight fitting junction between the nested sections 18a, b, c and etc.
- the inside diameter of the bell portion might be about 11.0 inches, or slightly less to provide a tight fit between the overlapping portions of the casing sections 18a, b, c and etc.
- the large diameter cone 20 can be positioned above, below or effectively at the same position as the small diameter cone 24, without departing from certain aspects of the invention. Also, it will be understood by those of ordinary skill in the art, and based upon this disclosure, that the large diameter corresponding to the inside diameter of the bell portion can be provided by a first collapsible or adjustable cone 22, that provides the desired bell portion diameter and that can be collapsed to a smaller diameter, together with a second cone 24 that provides the diameter for forming the mono diameter well bore casing. It will also be understood that in an alternative embodiment the expansion to the mono diameter can be provided by adjusting the diameter of cone 22 to effectively become the smaller diameter cone 24 having a diameter corresponding to the desired mono diameter. It will further be understood that in another alternative embodiment the cone 24 is a distinct cone 24 either fixed at the desired mono diameter size or expandable to the desired mono diameter size.
- Fig. 4 shows a schematic mono diameter casing forming apparatus 10, further depicting one arrangement of a mechanism for activating the expansion cone assembly 16 to expand the tubular member 14.
- the apparatus 10 is shown in a configuration for running into a wellbore 12.
- a drill pipe 30 supports the apparatus 10, as it is running down into the wellbore 12, with a connected float shoe 32.
- the drill pipe 30 may be a conventional drill pipe or other conventional down hole tubular support member.
- the float shoe may be a conventional float shoe or other tool guiding structure that serves the describe purpose attached to the drill pipe or other tubular support member.
- the float shoe 32 thus supports the new expandable tubular member 14 that is to be added to and expanded for engagement with the lower end of the mono diameter wellbore casing 18 that has been previously formed.
- An gripping tool 34 sometimes called an anchor that may be a device as shown or a conventional gripping tool or anchor, is provided to hold the expandable tubular member 14 fixed relative to one end of a hydraulic actuator 36, sometimes called a force multiplier mechanism that may be a device as shown or a conventional actuator or force multiplier.
- the hydraulic actuator 36 is configured and actuatable for moving the expansion cone assembly 16 relative to the expandable member 14, either in tension using sub 36a or in compression using sub 36b.
- Fig. 5 schematically shows an embodiment of the mono diameter casing forming apparatus 10, with the gripping mechanism 34 engaging the tubular member 14, with the tubular member 14 lifted off the bottom of the well bore 12 and with the expansion cone 16 pushed by actuator 36 into the open wellbore 12.
- a conventional dart 53 or ball is dropped to seal the float shoe 32, or another conventional shut-off device such as a mechanical valve or a velocity valve is used and activated, so that fluid 38 forced through the drill pipe 22 increases pressure to activate the gripping tool 26.
- the tension sub 36a of the actuator mechanism 36 is actuated. Pressure is increased in the drill pipe 30 and the gripping mechanism 34 is engaged to anchor the tubular member 14.
- Compression sub 36b is activated to lift the tubular liner 14 off the bottom of the wellbore and to push the cone assembly 16 into the open hole of wellbore 12.
- Fig. 6 shows the expansion cone assembly 16 expanded for radially expanding and plastically deforming the expandable tubular member 14.
- the expansion of the expansion cone assembly is activated in a conventional manner, as with a dart 42 that is passed with the fluid 38 down through the drill pipe 30 to thereby cause appropriate port alignment and/or appropriate valve activation for the expansion cone assembly 16.
- An optional sacrificial protective sleeve 40 that protects the expansion cone assembly 16 while it is running into the wellbore breaks off when the expansion cone assembly is expanded.
- the protective sleeve 40 may be formed of a plastic or composite material so that the sacrificial protective sleeve easily breaks off and does not interfere with the expansion of the tubular member 14.
- an apparatus 10 for forming a mono diameter wellbore casing 18 is positioned within a wellbore 12.
- the apparatus 10 includes, among other things, an expandable tubular member 14 and an adjustable expansion cone assembly 16.
- the expandable tubular member 14 may be supported by the grip tool 34 and/or the expansion cone assembly 16 and/or the float shoe 32.
- the apparatus 10 is then positioned into contact with the bottom 44 of the wellbore 12.
- a shear pin 46 is sheared and a dog locking sleeve 48 is driven upwardly thereby displacing a plurality of dogs 50 outwardly in the radial direction in a conventional manner.
- a ball 52 or conventional dart may then be placed within the ball or dart seat 54 of the apparatus by injecting fluidic material 38 into the apparatus 10.
- the expansion cone assembly is also actuated in a conventional manner, for example with the pressure caused by the ball 52 or a dart 42 (as shown in Fig. 6 above), to expand to the large diameter for expanding the bell.
- Pressure builds and the actuator 36 is activated in tension to draw the large cone 20 upward partially through the expandable tubular member 14.
- Pressure can be released and reactivated in the actuator 36 and gripping tool 34 to repeatedly stroke the large cone 20 of the expansion cone assembly 16 along the desired overlapping length L of the casing to thereby form the bell portion 22 of the casing.
- the large diameter cone 20 is actuated to collapse or adjust to a smaller diameter cone 24 corresponding -to the desired diameter of the mono diameter casing 18, using conventional actuation, for example, increased fluidic pressure and a rupture disc in an appropriate port (not shown) or an additional dart 56 injected with the fluidic material 38 into the apparatus 10 to a conventional dart seat 58.
- the gripping tool 34 is activated to lock the top end of the hydraulic actuator 36 to the expandable tubular member 14.
- the injected fluidic material 38 also causes the adjustable cone 24 to reach the desired diametrical size for forming the mono diameter casing 18.
- the continued injection of the fluidic material 38 furthermore increases the operating pressure within the apparatus thereby causing the hydraulic actuator 36 to pull the expansion cone 24 into the expandable tubular member 14. As a result, the expandable tubular member 14 is radially expanded.
- the continued upward movement of the expansion cone pulls the float shoe 32 to the bottom end of the radially expanded tubular member 14.
- the end of the radially expanded tubular member 14 will impact the dogs 50 thereby preventing the float shoe 32 from moving further in the upward direction.
- the continued upward movement of the expansion cone then will pull a sleeve expander cone 60 for the sleeve 62 upwardly thereby radially expanding a sleeve of the float shoe within the float shoe.
- the expansion cone assembly 16 is adjustable for providing two outside diameters, one outside diameter larger than the other outside diameter.
- the construction of the expandable cone assembly may also be constructed in accordance with the principles and design disclosed in U.S. provisional patent application serial no. 60/387,961 , attorney docket no. 25791.108, filed on 6/12/2002, the disclosure of which is incorporated herein by reference.
