Method and apparatus for completing wells with lateral branches

摘要

A method of completing a subterranean well and associated apparatus therefor. The subterranean well has a junction (196) of first, second and third wellbore portions (192,194,214), the first wellbore portion extending to the earth's surface. The method comprises the steps of: positioning in a well a first assembly (222) including a tubular member (220) and a tubular string (236), the tubular member being coaxially attached to the tubular string, the tubular string being disposed within the third wellbore portion (214) and the tubular member extending internally through the junction; and extending the third wellbore portion by conveying a cutting tool through the first assembly, the tubular member guiding the cutting tool through the junction. <IMAGE>
