The present invention provides a method and apparatus for mechanically interconnecting a lateral wellbore liner (50) to a main or parent wellbore casing (32). The present invention further provides a method of wellbore construction for the construction of multiple wellbores (44) which are interconnected downhole to form a manifold of pipelines in the reservoirs of interest. Provision is made for flow controls, sensors (40), data transmission, power generation, and other operations positioned in the lateral wellbores during the drilling, completion and production phases of such wellbores.

La présente invention concerne un procédé et un appareil permettant de relier mécaniquement ensemble une colonne perdue latérale de puits (50) à un tubage de puits (32) principal ou de base. En outre, cette invention concerne un procédé de construction de puits permettant de construire des puits multiples (44) reliés ensemble au fond pour former un collecteur de pipelines dans un réservoir voulu. En outre, on prévoit des régulateurs de débit, des détecteurs (40), une transmission de données, une production d'énergie, et d'autres opérations effectuées dans les puits latéraux au cours des phases de forage, de conditionnement et de production de ces puits.
