Abstract
A non-metallic liner for wellbore sidetrack operations is included in a wellbore tool assembly. The assembly includes a wellbore milling bottom hole assembly (BHA) that can mill through a wellbore liner material and material softer than the wellbore liner material. The assembly includes a wellbore liner that can be installed within a main well. The wellbore liner includes a first length segment made of the wellbore liner material and a second length segment axially attached to the first length segment. The second length segment is made of the non-metallic material. A window to form a lateral well is in the second length segment. The assembly includes a whipstock that can be installed within the main well in the first length segment of the wellbore liner after the wellbore milling BHA has milled the second length segment. The whipstock can guide the wellbore milling BHA towards the window.
