Abstract
This paper research operation a ways geostatistics of estimation deep wells at unknown point in kurkuk government . we applied in this paper simple , ordinary , Universal kriging technique its treated a ways task in geostatistics in estimation unknown point and addition arithmetic the variance estimation for all technique ,we obtained real data in this domain from Ministry of Water Resources in government, then we programmed all results of mathematical operation by Matlab language ,We have obtained encouraging results for ordinary kriging , because the variance estimation was less. This is evidence of the accuracy of this method in the estimate on the simple and Universal kriging methods.
