Abstract
Technologies for facilitating the placement of lateral liners from a main casing including a device for positioning a lateral liner in a lateral wellbore accessed through a window having a V-shaped downhole end, the liner junction placement device comprising: a lateral liner biasing member configured to be positioned between the lateral liner and the lateral wellbore at the window and configured to urge the lateral liner away from one side of the lateral wellbore.
Claims8
A liner junction placement device for positioning a lateral liner in a lateral wellbore accessed through a window having a V-shaped downhole end, the liner junction placement device comprising:
- a lateral liner biasing member carried on (i) the lateral liner outer surface or (ii) a lateral liner run-in tool, the lateral liner biasing member being configured to be positioned between the lateral liner and the lateral wellbore at the window and configured to urge the lateral liner away from one side of the lateral wellbore.
A method for placing a wellbore liner in a lateral wellbore extending from a main wellbore, the method comprising:
- moving the wellbore liner into the lateral wellbore through a window in the main wellbore;
- positioning a key coupled to the wellbore liner to bear against the lateral wellbore wall;
- biasing the wellbore liner by operation of the key into a position toward an upper end of the window;
- and
- securing the wellbore liner in the position.
