Patent abstract
A system and method for cutting windows for lateral wellbore drilling. A method of cutting a window through a sidewall structure for drilling a lateral wellbore through the window includes the steps of: providing an internal profile in the sidewall structure; then installing the sidewall structure in a parent wellbore; and then cutting the window through the sidewall structure, the cutting step including engaging a cutting tool with the internal profile. The cutting step may include resisting lateral displacement of the cutting tool due to engagement between the cutting tool and the internal profile.
