The transmissivity (T) distribution in the Dammam Formation aquifer within the State of Kuwait was investigated. It was found that up to 29% of the spatial variation in the log 10 T values could be explained by a multiple linear relation with the coordinates of the observation site, whereby the log 10 T showed a decreasing trend towards north and east. The deviations of the log 10 T from the first degree trend were kriged using the semivariogram constructed on the basis of the available T data. The resulting values were added to the logio T values estimated from the linear relation with the coordinates, to derive the most likely values of log 10 T at prespecified points. The technique provides estimates of transmissivity in areas away from the existing water fields. The T distribution with respect to the structure of the Dammam Formation was also investigated. The hypothesis that the transmissivity of the Dammam Formation was higher on the structural highs could not be substantiated, mostly because not enough data were available from such areas.
