Using the best geostatistic methods to interpolation pressure isobaric

Using convenient interpolation method can result to generate more precise and more accurate maps. The aim of this study is to determine the most appropriate interpolation method from a variety of Kiriging, invers distance weighting and variety of Co-Kiriging to zoning and drawing hydro-statics curves of Razjerd complex. For this purpose, the pressure of 60 different points of Razjerd complex was examined. The performance of inverse distance weighting (IDW) in pressure zoning was weaker than the Kiriging; and by increasing the power of reverse method, amount of R2 was decreased and the amount of RMSE was increased. The gained maps of simple Kiriging method had shown a perfect match with statistics obtained from installed logger barometers in complex. Generally, because of the grate accuracy, less computing and less requirement to data, the simple Kiriging method recommended to zoning pressure.
