Abstract
A whipstock assembly which includes a guide section and a setting section, wherein the setting section is configured to facilitate slight rotation of said setting section when the whipstock is set within a well, which rotation urges the guide section securely against the sidewall of the wellbore. Setting section includes a surface which will serve as a fulcrum, and a radially moveable element which serves to apply a force to one side of the whipstock, allowing the whipstock assembly to move as a lever, wherein the guide section is caused to meet the wellbore sidewall.
