Description
METHOD AND APPARATUS FOR EXPANDING AN ISOLATION TUBING
This invention relates to a straddle, and in particular a straddle for use in selectively isolating a section of tubing. The invention also relates to a method of isolating a section of tubing.
In the oil and gas exploration and production industries, subsurface hydrocarbon-bearing formations are accessed via casing-lined wellbores. The lower section of a bore, which intersects the hydrocarbon-bearing formation, is typically lined with perforated "liner", oil and gas flowing into the bore through the perforations. The location of the perforations is predetermined on the basis of surveys, to ensure that only selected formations are in fluid communication with the bore. Over the life of a well it may occur that the properties of particular formations change, for example the pressure in a formation may fall, or a formation may begin to produce an unacceptably high volume of water. In these circumstances it is known to run straddles into the liner, these straddles being sections of tubing with sealing arrangements at either end. A straddle may be located within the section of liner inter9ecting the problem formation, and the seals then set to isolate the section of liner between the seals. However, existing straddles are, problematic to set, and the requirement to accommodate the seals and a seal setting mechanism result

The straddle 10 comprises a section of expandable tubing 20 carrying seal bands 22 of relatively ductile metal at each end, and also grip bands 23 comprising small elements of relatively hard material in a relatively ductile matrix. The tubing 20 defines a solid wall and is of slightly smaller outside diameter than the liner 14.
.Initially, the tubing 20 is of substantially con~ra"r diameter along its length. The ends of the tubing 20a, 20b and formed of relatively ductile metal and are welded to a central tubing section 20c.
The straddle is run into the bore 12 on a tool string 26, and is mounted to the string 26 via an expander device 28 mounted to the lower end of the string 26. The expander device 28 comprises a body 30 carrying three radially movable rollers 32. The body 30 also.contains an axially movable piston which is coupled to a loading cone which cooperates with the tapered ends of the rollers 32.
Application of elevated fluid pressure, via the tool string 26, thus urges the rollers 32 radially outwardly. Shear pins 34 couple the straddle 10 to the expander body 30.

The straddle is run into the bore 12 on a tool string 26, and is mounted to the string 26 via an expander device 28 mounted to the lower end of the string 26.

Application of elevated fluid pressure, via the tool string 26, thus urges the rollers 32 radially outwardly. Shear pins 34 couple the straddle 10 to the expander body 30.
,In use, the straddle is run into the bore 12 on the tool string , 26 and positioned across the group of perforations 18 to be closed off from the bore. Pressure
6 is then applied to the expander 28 to activate the rollers 32; an initial application of elevated pressure causes the rollers 32 to extend radially, and deforms the tubing 20, towards a triangular form, such that the areas of tubing 2 O
adjacent the rollers 32 are pushed into contact with the inner surface of the liner 14. This initial contact is sufficient to prevent. relative rotation between the straddle 10 and the liner 14, such that when the string 26 and the expander 28 are rotated from surface the straddle 10 is held relative to the liner 14 and the pins 34 shear_ The expander 28 then rotates within the straddle 10 with the rollers 32 in rolling contact with the inner wall of the tubing 20. The rollers 32 are urged outwardly and progressively compress the tubing wall to create a localised reduction in wall thickness, and a corresponding increase in wall diameter. There is thus created a annular section of increased tubing diameter 36 at the tubing end section 20a, as shown in Figure 2, which provides an interference fit with the surrounding liner 14, the sealing bands 22 being deformed to form a fluid-tight seal between the expanded tubing 36 and the liner 14. The hard material in the grip bands 23 also assists in keying the tubing section 36 to the liner 14. There may be a degree of elastic and even plastic deformation of the liner 14, which will serve to provide a more secure location for the straddle 10.
Following creation of the annular extension 36, the pressure in the tool string 26 is reduced such that the
adjacent the rollers 32 are pushed into contact with the inner surface of the liner 14. This initial contact is sufficient to prevent. relative rotation between the straddle 10 and the liner 14, such that when the string 26 and the expander 28 are rotated from surface the straddle 10 is held relative to the liner 14 and the pins 34 shear_ The expander 28 then rotates within the straddle 10 with the rollers 32 in rolling contact with the inner wall of the tubing 20. The rollers 32 are urged outwardly and progressively compress the tubing wall to create a localised reduction in wall thickness, and a corresponding increase in wall diameter. There is thus created a annular section of increased tubing diameter 36 at the tubing end section 20a, as shown in Figure 2, which provides an interference fit with the surrounding liner 14, the sealing bands 22 being deformed to form a fluid-tight seal between the expanded tubing 36 and the liner 14. The hard material in the grip bands 23 also assists in keying the tubing section 36 to the liner 14. There may be a degree of elastic and even plastic deformation of the liner 14, which will serve to provide a more secure location for the straddle 10.
Following creation of the annular extension 36, the pressure in the tool string 26 is reduced such that the
7 rollers 32 may retract. The expander 28 is then advanced towards the lower end of the straddle 10, and engages a stop 38 provided on the lower end of the tubing 20. The pressure in the tool string is then increased once more to actuate the rollers 32, and the expander 28 is rotated to create a second annular section of increased diameter 40.
The expander 28 may then be deactivated and retrieved from the bore, leaving the straddle 10 locked in place in the bore, and serving to isolate the formation 16 from~the bore.
To remove the straddle 10, the locking and sealing sections 36, 40 are milled out, and the remaining section of tubing then removed.
In other embodiments, the increased diameter sections 36,40 may be formed simultaneously, by provision of two expanders located one at either end of the straddle.
Reference is now made to Figure 3 of the drawings, which illustrates a permanent straddle 50 in accordance with another embodiment of the invention locked and sealed in a bore 52. The straddle 50 is located in a substantially similar manner to the straddle 10 described above, however the straddle tubing 54 has been deformed along its whole length, such that there is a much larger area of contact between the tubing 54 and the surrounding liner 56, and a smaller loss in cross-section in the liner 5~ fxom the provision of the straddle 50.
