Abstract
Systems and methods presented herein include a drilling system that includes a deflecting device having an internal passage extending therethrough, and a flexible drilling assembly configured to extend through the internal passage of the deflecting device, and to create a perforation lateral tunnel in a wellbore. The flexible drilling assembly includes a flexible drive shaft configured to rotate relative to the internal passage of the deflecting device. The flexible drilling assembly also includes a cutting bit disposed at a first axial end of the flexible drilling assembly. The flexible drilling assembly further includes a slider tube disposed at a second axial end of the flexible drilling assembly. In addition, the flexible drilling assembly includes a slider radially disposed within the slider tube. The slider is hydraulically configured to compensate for expansion and compression of the flexible drive shaft while the perforation lateral tunnel is being created in the wellbore by the flexible drilling assembly.
