This video describes a new capability whereby RockWorks16 can be used to automatically determine the path for a horizontal well that starts out as a vertical borehole at a designated location and then curves (based on a user-defined radius of curvature) into a pay-zone as defined by two grid models.  The path will then automatically route itself along the mid-line of the two surfaces until reaching a user-defined point.

Caveat: This program assumes that hole starts out vertically.
