  • Modeling Geological Strata Using Weighted Parameters
    Publication number: 20210165124
    Abstract: Geological stata can be modeled using weighted parameters. For example, geological data representative of strata in a subterranean formation can be received. A weight for a parameter usable to generate a geological model can be determined. Examples of the parameter can include (i) a first parameter for reducing a change in a thickness of a stratum, (ii) a second parameter for maintaining a minimum thickness of the stratum, (iii) a third parameter for maintaining a maximum thickness of the stratum, (iv) a fourth parameter for reducing a curvature in the thickness of the stratum, (v) a fifth parameter for a user-provided indication of a feature of the stratum, or (vi) any combination of these. The geological model can be generated by concurrently solving a system of equations using the weight and the geological data. The geological model can be displayed and can visually represent the cross-sectional shapes of the strata.
