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).
