Abstract: A method can include receiving input for a multiwell pad; selecting, based at least in part on a portion of the input, a template for the multiwell pad; generating, based at least in part on the template, well trajectories for the multiwell pad, where each of the well trajectories extends from a surface location of the multiwell pad to one or more reservoir target locations and where each of the well trajectories includes at least one curve generated using one or more dogleg severity values and one or more geometric control points that are not required to lie on one or more of the well trajectories; and outputting specifications for the generated trajectories of the multiwell pad.

Abstract: A method of preventing a collision of a subject wellbore in a downhole environment includes receiving offset wellbore data corresponding with one or more offset wellbores and identifying, based on the offset wellbore data, one or more no-go zones for each of the one or more offset wellbores. The method further includes determining a plurality of safe points corresponding with a potential intersection of the subject wellbore with the one or more no-go zones and, defining an escape zone within the plurality of safe points. The method further includes determining a trajectory for the subject wellbore within the escape zone.

Abstract: A method may include receiving input for a multiwell structure and subsurface target locations, where the multiwell structure includes slots; generating, based at least in part on the input, a position for the multiwell structure, slot-well assignments for the slots, and well trajectories, where each of the well trajectories extends from an assigned one of the slots to one or more of the subsurface target locations; and outputting a set of specifications for the position for the multiwell structure, the well trajectories, and an order for drilling the well trajectories.

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.
