Analysis of Exploration Wells on Aquifer in Kaliwungu Formation and Regional Planning Recommendations

Abstract Infrastructure development in the northern coast of Java continues to take place. The study and support subsurface geological data value hydrogeological parameters is one important sustainable development. existence well exploration reportedly can researchers for model validation calibration. We carried out One-Dimensional Two-Dimensional geoelectrical acquisition along with drilling Kaliwungu Formation which was lined Halang Formation. Ten points dimensional two lines VES method (Vertical Electrical Sounding), a depth range 100m Schlumberger Wenner-Schlumberger configurations profiling have reflected area dominated by aquitard (silty clay) resistivity values < 20 ohm.m. result then followed up analysing logging compared lithology cutting results 108m deep drill hole. Value properties pumping test, were test analysed using cooper – Jacob single software, hydraulic conductivity 6 x 10 -9 m/s, transmittivity 5.6 -7 m 2 /s. Based on Farvolden Method, safe yield found be comparable according Johson 3-8%.
