Methods and devices for preventing computationally explosive calculations in a computer for model parameters distributed on a hierarchy of geometric simplices
| DWPI Title: Method for preventing computationally explosive calculations arising in computer, involves utilizing final composite Earth model to characterize process and physical object in which characterization is created by processor |
| Abstract: A computer-implemented method of preventing computationally explosive calculations. The method includes obtaining, by a processor of the computer, measured data of one of a physical process or a physical object; performing hierarchical numerical modeling of a physical process inclusive of an Earth model containing at least one of (a) infrastructure in the ground and (b) a formation feature in the ground, wherein predicted data is generated; comparing the measured data to the predicted data to calculate an estimated error; analyzing the estimated error via an inversion process to update the at least one of the Earth model and infrastructure model so as to reduce the estimated error and to determine a final composite Earth model of at least one of the infrastructure and the feature; and using the final composite Earth model to characterize at least one of the process and the physical object. |
| Use: Method for preventing computationally explosive calculations arising in a computer (claimed). |
| Advantage: The method enables representing the feature by infinitesimally thin, arbitrarily oriented and connected facets and edges of the model, thus eliminating a need for computationally explosive volumetric discretization of the feature or the infrastructure. |
| Novelty: The method involves performing hierarchical numerical modeling of a physical process inclusive of an Earth model containing an infrastructure in a ground and a formation feature in the ground in which predicted data are generated by a processor. Measured data are compared to the predicted data to calculate an estimated error by the processor. The estimated error is analyzed through an inversion process to update the Earth model and an infrastructure model to reduce the estimated error and determine a final composite Earth model of the infrastructure and the feature by the processor. The final composite Earth model is utilized to characterize the process and a physical object in which characterization is created by the processor. |
