Aquifer porosity prediction base on resistivity data and water conductivity
Keywords:
aquifer porosity, electrical conductivity, geoelectric tool, resistivity, wells waterAbstract
The research of aquifer porosity prediction based on resistivity data and water conductivity was conducted. The research was a case of study that conducted at Desa Bugbug, Karangasem Regency in Bali. Resistivity data were taken by geoelectric tools set off. Water conductivity data was obtained by directly measuring the water conductivity of the wells drilled based on geoelectric data. In regard the measurement results was obtained 26.5 ohm.m of resistivity aquifer and the water conductivity was 0.02 s/m so that the aquifer porosity based on the calculation was 39.9%. The implications of this calculation were to obtain data that serves as a soil porosity aquifer, e.g. as the soil porosity at existing wells site, it was enough conducted resistivity measurements on the spot and measure the conductivity of wells water. Thus the process was expected to be more practical.
