Patent

CA 2184943

A downhole multilateral completion tool is disclosed which includes a pre-machined window joint and a production tube adapted to be moved downhole through the window joint and kicked off into the pre-drilled lateral. A flange and seal form a part of the uphole end of the production tube and provide a 3500 psi seal after the production tube is placed in the lateral. The invention, moreover, includes an energizing sleeve which biases the flange into a sealed position and a packer which by pulling the production tube, enhances the seal of the flange.
