MT survey in the Minaminoshiro oil field; Minaminoshiro chiiki ni okeru MT ho ni yoru sekiyu tanko (sanjigen MT ho chosa no kento). 1

Abstract

Preliminary experiment, investigation, and study are conducted prior to an experimental 3-D MT (magnetotelluric) survey planned to be carried out in the Minaminoshiro district, Akita Prefecture. In the preliminary investigation, MT measurements were performed at nine locations. It was anticipated that national highways, waste treatment plants, high-voltage power lines, and railways in presence in the district would act as noise sources. Although the impact of such noise was detected in the single site treatment result, yet it was found that it would be mostly eliminated by use of the remote reference treatment. It was learned that the resistivity structure in this district was quite low in contrast or 1 ohm/m against 30 ohm/m, but the result of 3-D model calculation indicated that a sufficient analysis would be possible even in such a low contrast case. Furthermore, as the result of the study of the density of observation stations in the magnetic field, it was found that changes in the response of magnetic field to the resistivity structure would be approximately 2% at the maximum and that the ill effect on the result of measurement would be of the negligible magnitude even when a single magnetic field observation station is deployed  More>>
