Abstract
This paper presented a methodology for delineating capture zones of multi-pumping wells using backward particle tracking in geostatistically generated hydraulic conductivity fields based on field data. Under multi-pumping conditions, random walk particle tracking was applied to estimate spatial probability distributions of introduced ensemble cells having the probability that particles within cells reach the pumping wells. Ensemble of the particle evolutions toward pumping wells from a cell was also proposed as the ensemble travel-times and was presented another aspect relevant to spatial distributions of travel-times of cells. Proposed methodologies provided some proper outcomes corresponding to the pumping rates and pumping locations.
