Single borehole hydraulic tests for a rock mass in a large depth are classified to two categories; a variable condition and invariable condition. The first test group has typically PW,SW and SWS tests, and the second has RW and RWS tests. Because the most of these tests have been developed for an aquifer(relatively highly permeable), it is necessary to pay attention on conducting these tests for a rock mass(lowly permeable). On the view point, the report summaries analysis methods and supporting techniques to them which work effectively and accurately.Also, an ideal duration time of a test and a scheme of judging a stop time of a test are proposed in consideration of obtaining available data. Finally, a data set of RW test is analyzed. The estimations, hydraulic conductivity and specific storativity, depend highly on the selected aquifer model. The dual-porosity model with pseudo-steady condition is recognized available and it is compiled into the analysis system which has been developing.
