Abstract
Techniques are described for determining an optimal resolution for a grid to be used in solving inverse problems. Reference physical fields may be computed based on model data for the computational grid at a starting resolution. Cells in the computational grid may be split in a plurality of iterations to provide finer resolution. The model data may be perturbed by introducing different physical property values to the cells. The physical fields may be calculated based on the perturbed model data. A comparison may be made between the reference physical fields and the calculated physical fields based on the perturbed model data for the purpose of determining whether cell splitting should continue.
