Title:
INTERPOSED JOINT SEALING LAYER METHOD OF FORMING A WELLBORE CASING
Document Type and Number:
WIPO Patent Application WO2004018823
Kind Code:
B1
Abstract:
A method of forming a wellbore casing within a borehole (10) that traverses a subterranean formation, is provided by assembling a tubular liner by coupling a multi-layer tubular insert (92) threaded portion (24) of a first tubular member (16), and coupling a threaded portion (22) of a second tubular member (14) to the threaded portions (24) of the first (16) tubular member and the multi-layer tubular insert (92). the tubular liner assembly is positioned within the borehole (10); and the tubular liner assembly within the borehole (10) is radially expanded and plastically deformed. The multi-layer tubular insert (92) 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.
