6. Conclusions
The investigation of the hydrogeologic characterization has been
included two single-well pumping tests design. This also indicates the
formation (Early Miocene age and Boka Bil) and the safe water zone by
the lithologic interpretation. The pumping test has also indicated the
performance of well criteria and aquifer characteristics. The well
performance has evaluated by applying the graphical analysis of the
Jacob methods. It has estimated the formation and well loss of drawdown.
The ideal design of the two wells have been developed for groundwater
exploration by choosing the accurate model of the screen as well as
casing of a well. The pumping test results have also shown the aquifer
flow is mainly laminar, but the turbulent flow is highly negligible
because the well loss is much lower than the formation losses. The test
of two wells has been properly developed for optimizing the greater
effectiveness by removing fine materials from the face of two well. The
pumping test has helped to develop transmission as much of the aquifer’s
wideness as possible. Higher specific capacity values and transmissivity
values (evaluate from test of specific capacity data) has indicated that
the aquifer has been considered as higher productivity of water. The
total efficiency of the two wells (from 95.3% to 98.5%) and these
indicated the proper design and higher effective well for water
exploration.
