Implicit property modeling

A system for simulating a process of a geological structure, the system comprising:

• at least one electronic persistent memory storing a first digital model comprising structural data representing a geological structure, wherein the geological structure comprises a folded and faulted geological domain, wherein the folded and faulted geological domain comprises a discontinuous layer that includes two or more disjoint portions that are not physically connected, wherein the first digital model is a 2D model that comprises an implicit function that assigns different values to represent different materials in the folded and faulted geological domain, wherein the implicit function receives a coordinate of the folded and faulted geological domain as an input, wherein the implicit function generates one of the values corresponding to one of the materials present at a location of the coordinate as an output, wherein the implicit function defines isolines and isobands, wherein the isolines have a same value in the implicit function, wherein the isolines represent boundaries between two or more layers in the folded and faulted geological domain, and wherein the isobands are between the isolines and represent the materials in the two or more layers;
• and
• at least one electronic processor that executes instructions to perform operations comprising:
• selecting at least one marching technique based in part on a grid dimension and a grid cell shape of a grid on the first digital model;
• applying the at least one marching technique to at least a portion of the structural data of the first digital model to identify at least some boundary data;
• populating a second digital model based in part on the first digital model, a property, and the boundary data;
• performing a simulated process of the geological structure using the second digital model, wherein the simulated process comprises simulated fluid extraction from the geological structure, simulated fluid injection into the geological structure, or simulated wellbore insertion into the geological structure;
• and
• causing part of an actual process to occur in response to results of the simulated process, wherein the actual process comprises actual fluid extraction from the geological structure, actual fluid injection into the geological structure, or actual wellbore insertion into the geological structure.

A non-transitory computer-readable medium storing instructions that, when executed by at least one processor, are configured to cause a computing system to perform operations, the operations comprising:

• obtaining a first digital model comprising structural data representing a geological structure, wherein the geological structure comprises a folded and faulted geological domain, wherein the folded and faulted geological domain comprises a discontinuous layer that includes two or more disjoint portions that are not physically connected, wherein the first digital model is a 3D model that comprises an implicit function that assigns different values to represent different materials in the folded and faulted geological domain, wherein the implicit function receives a coordinate of the folded and faulted geological domain as an input, wherein the implicit function generates one of the values corresponding to one of the materials present at a location of the coordinate as an output, wherein the implicit function defines isosurfaces and volumetric objects, wherein the isosurfaces have a same value in the implicit function, and wherein the volumetric objects are between the isosurfaces;
• selecting at least one marching technique based in part on a grid dimension and a grid cell shape of a grid on the first digital model;
• applying the at least one marching technique to at least a portion of the structural data of the first digital model to identify at least some boundary data;
• populating a second digital model based in part on the first digital model, a property, and the boundary data;
• performing a simulated process of the geological structure using the second digital model, wherein the simulated process comprises simulated fluid extraction from the geological structure, simulated fluid injection into the geological structure, or simulated wellbore insertion into the geological structure;
• and
• causing part of an actual process to occur in response to results of the simulated process, wherein the actual process comprises actual fluid extraction from the geological structure, actual fluid injection into the geological structure, or actual wellbore insertion into the geological structure.
