    摘要： Methods and apparatus are provided for performing an expedited shoe test using an expandable casing portion as an annular fluid barrier. Such an expandable annular fluid barrier may be used in conjunction with cement if so desired but cement is not required. Further provided are methods and apparatus for successfully recovering from a failed expansion so that a shoe test can be completed without replacement of the expandable casing portion.

    摘要： A method of testing a tubular member and selecting tubular members for suitability for expansion by subjecting a representative sample the tubular member to axial loading, stretching at least a portion of the tubular member through elastic deformation, plastic yield and to ultimate yield, and based upon changes in length and area calculating an expandability coefficient indicative of expandability of the tubular members and selecting tubular members with relatively high coefficients indicative of good expandability.

    摘要： A method of forming a wellbore casing within a borehole that traverses a subterranean formation, is provided by assembling a tubular liner by coupling a multi-layer tubular insert assembly to a threaded portion of a first tubular member, and coupling a threaded portion of a second tubular member to the threaded portion of the first tubular member and the multi-layer tubular insert. The tubular liner assembly is positioned within the borehole; and the tubular liner assembly within the borehole is radially expanded and plastically deformed. The multi-layer tubular insert includes a first tubular insert having a first modulus of elasticity; and a second tubular insert coupled to the first tubular insert having a second modulus of elasticity. The first modulus of elasticity is different from the second modulus of elasticity.
