METHOD (EMBODIMENTS) FOR DETECTING ANOMALOUS PATTERNS IN GEOPHYSICAL DATASETS USING WINDOWED STATISTICAL ANALYSIS AND METHOD FOR PRODUCING HYDROCARBONS FROM SUBSURFACE REGION

摘要

Method for identifying geologic features from geophysical or attribute data using windowed principal component (or independent component) analysis. Subtle features are made identifiable in partial or residual data volumes. The residual data volumes (24) are created by (36) eliminating data not captured by the most prominent principal components (14). The partial data volumes are created by (35) projecting the data on to selected principal components. The method is suitable for identifying physical features indicative of hydrocarbon potential.
