Abstract: A method and system for finding and efficiently evaluating and selecting a wellbore path that accounts for placement rules and the presence of existing wells. A topological representation of the connected paths is created and managed. The topological representation may be generated as a pre-computed database of space information that represents the locations of existing wells and accounts for restrictions such as anti-collision and the parameters, including geological and drilling equipment parameters. Using such a representation, the design of a wellbore path may be completed quickly and more efficiently. The topology may represent all connected space for a section of the subsurface. This topological representation may be used to evaluate all possible paths from the starting point (surface location, tie-in point for a sidetrack, tie-in point for replanning, etc.) to the target and enable selecting the path that meets the conditions and is optimized for the existing constraints.
