Definitions
- the invention relates to a method and system for inhibiting slip of an expandable well tubular assembly wherein an upper end of a lower well tubular is expanded within a lower end of a previously installed well tubular.
- a well tubular is expanded by moving an expansion cone therethrough.
- the expansion cone is connected to a drill string that is pulled up, whilst the upper end of the tubular is maintained in a fixed position within an previously installed well tubular by a radially expanded top anchor assembly.
- the top anchor assembly When the expansion cone reaches the top anchor assembly the top anchor assembly needs to be retracted and pulled up by the expansion cone and then upward motion of partially expanded tubular needs to prevented by friction between the outer surface thereof and the inner surface of the previously installed well tubular.
- a method for inhibiting slip in an area of overlap between lower well tubular of which an upper end is expanded against a lower end of a previously installed upper tubular comprising providing the lower well tubular with an outer surface having an upper section that is configured to be expanded against the lower end of the upper well tubular and that has a larger roughness than other parts of the outer surface.
- the upper section of the outer surface may be roughened and/or coated with a coating having a high friction coefficient ( ⁇ o ) of at least 0.055, optionally of at least 0.1, and the lower well tubular may have an inner surface coated with a lubricating coating having a lower friction coefficient ( ⁇ i ) than the friction coefficient ( ⁇ o ) of the coating on the upper section of the outer surface and the lower well tubular may be expanded by:
- the invention also provides a well tubular for use in the method according to the invention, the tubular being configured to be radially expanded and comprising an outer surface having an upper section that is configured to be expanded against the lower end of the another well tubular and that has a larger roughness than other parts of the outer surface.
- the upper section of the outer surface of the well tubular may be roughened and/or coated with a coating having a high friction coefficient and the well tubular may have an inner surface which is coated with a lubricating coating having a low friction coefficient thereby providing a well tubular which is configured to be radially expanded by moving an expansion cone therethrough.
- the inner surface of the tubular may be coated with a lubricating coating having a friction coefficient ( ⁇ i ) of at most 0.045, optionally of at most 0.025.
- the upper section of the outer surface of the well tubular may be expanded against an inner surface of another well tubular and the tubulars may form part of a casing or liner assembly of a hydrocarbon fluid production well, which assembly may comprise:
- Fig.1 shows how a lower well tubular 1 is expanded by moving an expansion cone 2 therethrough.
- the expansion cone is connected to a drill string 3 that is pulled up as illustrated by arrow 4, whilst the upper end 1A of the lower tubular is maintained in a fixed position within an upper well tubular 5 by a radially expanded top anchor assembly 6.
- such upward motion or slip is inhibited by roughening an upper section of the outer surface of the lower well tubular 1 and/or providing said upper section with a high friction coating 8 having a friction coefficient ⁇ o of at least 0.055, optionally of at least 0.1.
- an inner surface of the lower tubular 1 is coated with a lubricating coating 7 to lubricate the longitudinal movement of the cone 2 therethrough, which lubricating coating 7 may have a friction coefficient ⁇ i of at most 0.045, optionally of at most 0.025.
