  • Interactively planning a well site
    Patent number: 10584570
    Abstract: A method and systems for dynamically planning a well site are provided herein. The method includes generating, via a computing system, a three-dimensional model of a hydrocarbon field including a reservoir. The method also includes determining a location for a well site based on the three-dimensional model and determining reservoir targets for the determined location and a well trajectory for each reservoir target. The method also includes adjusting the location for the well site within the three-dimensional model and dynamically adjusting the reservoir targets and the well trajectories based on the dynamic adjustment of the location for the well site. The determination and the dynamic adjustment of the location, the reservoir targets, and the well trajectories for the well site are based on specified constraints. The method further includes determining a design for the well site based on the dynamic adjustment of the location, the reservoir targets, and the well trajectories for the well site.
