    • Methods for creating and using discretized physics-based models of subsurface regions, which may contain a hydrocarbon reservoir or other subsurface feature(s). The methods may include selecting a pre-solved model, applying a mesh to the pre-solved model, defining the shape of the subsurface region to be modeled, and transforming the pre-solved model, to which the mesh has been applied, to the shape of the subsurface region. In some methods, the pre-solved model is an idealized model. In some methods, the mesh is applied to a solution of potential field lines associated with the pre-solved model, and in some methods, the solution of potential field lines is a composite solution of a plurality of solutions of potential field lines. In some methods, one or more supershapes are used to define the shape of the subsurface region. In some methods, a hyperelastic strain deformation calculation is utilized for the transforming.
    • 用于创建和使用可能包含烃储层或其他地下特征的地下区域的基于离散物理的模型的方法。 所述方法可以包括选择预先解决的模型,将网格应用于预先确定的模型,定义待建模的地下区域的形状,以及将已应用网格的预先解决的模型转换为 地下区域的形状。 在一些方法中,预先解决的模型是一个理想化的模型。 在一些方法中,将网格应用于与预定模型相关联的潜在场线的解,并且在一些方法中,势场线的解是多个势场解的解的复合解。 在一些方法中,使用一个或多个超级形状来限定地下区域的形状。 在一些方法中,使用超弹性应变变形计算进行变换。

    • Methods for generating a surrogate model for subsurface analysis may include identifying input parameters for the subsurface analysis, and selecting a range of values for the identified parameters. The methods also include selecting a design of experiments method for filling sampling points within the ranges of values for the identified input parameters. The design of experiments method may be a classical method or a space-filling technique. The methods also include filling sampling points within the ranges of values for the identified input parameters. The sampling points are filled based on the design of experiments method selected. The methods further include acquiring output values for each of the selected sampling points, and constructing a surrogate model based upon the output values for at least some of the selected sampling points. The surrogate model is a mathematical equation that represents a simplified model for predicting solutions to complex reservoir engineering problems.
