Abstract

Official abstract text for this publication.

An annular barrier has a tubular part, and a downhole expandable tubular to be expanded in an annulus downhole from a first outer diameter to a second outer diameter to abut against an inner face of a casing or borehole. The downhole expandable tubular has a first end section, a second end section and an intermediate section between the first end section and the second end section, the downhole expandable tubular surrounding the tubular part. Each end section of the downhole expandable tubular is connected with the tubular part and extends along a longitudinal axis, and defines an annular barrier space between the tubular part and the downhole expandable tubular. The tubular is made from one metal tubular blank of one metal material, the metal material of the end sections having a higher yield strength than the metal material of the intermediate section.

First claim

Opening claim text (preview).

1 . An annular barrier to be expanded in an annulus between a well tubular structure and an inside face of a casing or borehole downhole for providing zone isolation between a first zone and a second zone of the casing or borehole, the annular barrier having an axial extension and comprising: a tubular part, the tubular part being a separate tubular part or a casing part for mounting as part of the well tubular structure, a downhole expandable tubular to be expanded in the annulus downhole fr…
