Abstract

A tubular portion apparatus (10; 100; 300; 400) to be secured and sealed to another tubular (36) is described as is a method of securing and sealing a tubular portion (10; 100; 300; 400) to an existing downhole tubular (36) such as a casing string (36). The tubular portion (10; 100; 300; 400) comprises a central portion (14), an upper (16) and a lower (18) portion adjacent to the central portion (14) along a longitudinal axis of the tubular portion (10; 100; 300; 400). The tubular portion (10; 100; 300; 400) is formed from a main material and an additional material to strengthen the upper (16) and the lower (18) portion of the tubular portion (10; 100; 300; 400).
