Geophysical Study of the Electrical Resistivity at Minami Noshiro Area, Japan

E027 GEOPHYSICAL STUDY OF THE ELECTRICAL RESISTIVITY AT MINAMI NOSHIRO AREA JAPAN Abstract 1 AHMED KHALIL GAD ELQADY AND KEISUKE USHIJIMA AUTHOR Minami-Noshiro oil field is considered as one of the most important oil fields in Japan. A threedimensional magnetotelluric (MT) survey was conducted in this area by Japan National Oil Corporation (JNOC). In this study the magnetotelluric data have been used to image the electrical conductivity of the subsurface in the study area. The used frequency of the MT data was ranging from 0.00055 to 320 Hz. The study of the dimensionality and directionality of the regional electrical structures
