| Summary: | Self-Potential (SP) is one of the simple geoelectrical methods and it is still used in many fields of applied geophysics. Since the SP method is sensitive to primary flows, such as fluid flow, it has been used often to detect or monitor hydrology systems. The development of quantitative interpretation by means of computational modeling is still needed to provide better interpretation of complex subsurface structure and the problem of crosscoupled flows due to cavity system. In this modeling of the electrokinetic effects such as streaming potential, all that is required is a velocity model, models of the crosscoupling parameters and the electric conductivity. With this velocity field and the physical properties models, the algorithm is used to calculate the electric current sources and the resultant selfpotential. In this final project, we have done a Self-Potential modelling for Japan cave TAHURA Ir. H. Juanda, West Java, which is combined with 1D resistivity, 2D resistivity, flow fluid modelling, and Maribaya Fault analysis in order to estimate strength of material structure of the Japan cave and its surroundings. |
