Abstract
The purpose of this study was to determine what effect well efficiency has upon the results of in-situ permeability tests.
Several in-situ permeability tests were performed on wells during various stages of their development. The well efficiency was determined each time an in-situ test was performed. An accurate value of permeability was determined by performing local aquifer pumping tests. The accuracy of the results of the in-situ tests with respect to the aquifer pump test results were then compared to the efficiency of the well at the time of the test.
Test results showed that a linear relationship exists between well efficiency and the accuracy of slug test results. A direct one to one relationship exists using the Bouwer and rice (1976) method of data analysis, while a one to two relationship exists using the Hvorslev (1951) method. Thus, the assumption by the suthors that the effect of well losses is negligible is incorrect.
