Abstract
A whipstock/billet anchor can be set in open hole such that one or more slips initially shift laterally near the lower end or below the whipstock/billet while the upper end reacts and gets pushed against the wellbore. Then with the top of the whipstock/billet against the wellbore another slip gets a bite to secure the whipstock/billet in a manner where the wellbore gives it some support near its upper end as a drill bit engages the whipstock/billet to make a lateral. Open and cased hole application is contemplated. The anchor also allows running in and supporting a tubular string below and a tool above with the further option of cocking the tool for better support before securing it.
