Abstract
It may be required at a well site to create a lateral wellbore from a primary wellbore. A dissolvable whipstock assembly may be positioned within a primary wellbore to deflect a mill or drill bit to create a secondary wellbore. The dissolvable whipstock assembly may include a wear plate coupled to a whipstock. The wear plate comprises an incline or ramp to deflect a mill or drill to a casing exit or pre-milled window to create the secondary wellbore. The wear plate comprises a material that is strong enough to withstand the force applied by the drilling and is degradable or dissolvable. Any one or more components of the whipstock may be dissolvable such that at least a portion of the whipstock dissolves to form a pathway through any remaining portion of the dissolvable whipstock and the primary wellbore.
