Abstract
AbstractIn this work, a new nonstationary multiple‐point geostatistical methodology called vector field‐based simulation is presented. This method generates multiple realizations of the phenomena being modeled, whose spatial continuity is described by a training image. It can be applied in reservoir characterization and can be used to study the behavior of hydrogeological systems. The main novelty of this work is that nonstationarity is addressed through a vector field inferred from the training image. This field represents the directions in which the image develops and controls the multiple‐point statistics methods (MPS) simulation. Additionally, our simulation is adapted to support hard data conditioning. The method is tested, and the realizations exhibit a similar morphology as the training image but with substantial variability. Furthermore, in the results it can be seen that the connectivity presented in the training image is preserved.
