원유광(源油鑛)의 규모 및 추정을 위한 자기장(磁氣場)의 통계적 분석(統計的 分析)

A statistical analysis of magnetic field intensities for estimating the size and orientation of the petroleum deposit

A statistical analysis for detecting deviations from normal magnetic field intensities, caused by the introduction of magnetite materials into man-made fissures and cracks at subsurface levels is presented. For detecting such deviations it turns out the comparison of two different field measurements measured at two different sites far from each other is more efficient than the study of the only measurement by the univariate and bivariate time series analysis.
