Abstract
Provided are a system and method for calculating and selecting a convergence path based on cost. In one example, the method includes identifying multiple geometric convergence paths that each provides a convergence solution from a defined bottom hole assembly (BHA) location to a target path. A total monetary cost is calculated for each of the geometric convergence paths using an offset cost based on a distance of the geometric convergence path from the target path, a curvature cost based on an amount of curvature of the geometric convergence path, and a time cost based on an estimated amount of time needed to drill the geometric convergence path. The total monetary costs of the geometric convergence paths are compared and one of the geometric convergence paths is selected based on the total monetary cost of that geometric convergence path relative to the total monetary costs of the other geometric convergence paths.
