    摘要: A method of interconnecting first and second wellbores. The method comprises the steps of: forming a radially enlarged cavity (20) in the first wellbore (12) below casing (14) lining the first wellbore (20); positioning a wellbore connector (22) within the cavity (20), the wellbore connector (22) being configurable in expanded and contracted configurations; and expanding the wellbore connector (22) within the cavity (20).

    摘要: A method of forming a wellbore junction using a tubular member (28) having an opening (32) formed through a sidewall portion thereof and a blocking member (34) which is selectively positionable relative to the opening (32) in a first position in which the blocking member (34) blocks the opening (32) and in a second position in which the blocking member (34) permits access to the opening (32). The method involves the steps of drilling a first wellbore (12), positioning the tubular member (28) within the first wellbore (12), positioning the blocking member (34) in the second position, and drilling a second wellbore (60) by passing at least one cutting tool through the opening (32).
