    摘要： Method for determining one or more optimal well trajectories and a drill center location for hydrocarbon production. A well path and drill center optimization problem (55) is solved in which one constraint is that a well trajectory must intersect a finite size target region (61) in each formation of interest, or in different parts of the same formation. The finite target size provides flexibility for the optimization problem to arrive at a more advantageous solution. Typical well path optimization constraints are also applied, such as anti-collision constraints and surface site constraints (62).

    摘要： A method, including: identifying a well target or reservoir segment; defining a dynamic surface grid, the dynamic surface grid being a representation of a ground surface, sea-level, or subsea surface above a reservoir upon which a drill center is locatable, and the dynamic surface grid including a plurality of cells that define potential locations for the drill center; assigning, to each of the plurality of cells of the dynamic surface grid, a value of a drilling or geologic attribute that defines a quality of a drill center position relative to the well target or reservoir segment; and selecting, based on a value of the drilling or geologic attribute, a location for the drill center corresponding to a location represented on the dynamic surface grid.

    摘要： There is provided a system and method for planning a well path. An exemplary method comprises defining a proxy constraint volume as a three-dimensional (3D) cellular volume where each cell has at least one value derived from data from a 3D earth model. An initial well path is defined within user defined drilling parameter constraints. The exemplary method comprises defining acceptable constraint parameters to be applied to values derived from an intersection of the initial well path and the proxy constraint volume. If the intersection of the initial well path and the proxy constraint volume is not within the acceptable constraint parameters, the initial well path may be iteratively adjusted to create successive well paths until at least one of the successive well paths is within the acceptable constraint parameters for the values derived from the intersection of the well path and proxy constraint volume.
