摘要:
Method for analyzing seismic data representing a subsurface region for presence of a hydrocarbon system or a particular play. Seismic attributes are computed, the attributes being selected to relate to the classical elements of a hydrocarbon system, namely reservoir, seal, trap, source, maturation, and migration. Preferably, the attributes are computed along structural fabrics (1) of the subsurface region, and are smoothed over at least tens or hundreds of data voxels. The resulting geologic attributes (2) are used to analyze the data for elements of the hydrocarbon system and/or recognition of specific plays, and for ranking and annotating partitioned regions (3) of the data volume based on size, quality, and confidence in the prospectivity prediction (5). A catalog (8) of hydrocarbon trap configurations may be created and used to identify potential presence of hydrocarbon traps and/or aid in scoring (4) and ranking partitioned regions as hydrocarbon prospects.
摘要:
A method of transforming geologic data relating to a subsurface region between a geophysical depth domain and a geologic age domain is disclosed. A set of topologically consistent surfaces is obtained that correspond to seismic data. The surfaces are enumerated in the depth domain. An age is assigned to each surface in the depth domain. The age corresponds to an estimated time of deposition of the respective surface. An age mapping volume is generated. An extent of the age domain is chosen. A depth mapping volume is generated. Both the age mapping volume and the depth mapping volume are used to transform geophysical, geologic, or engineering data or interpretations between the depth domain and the age domain and vice versa. The geophysical, geologic, or engineering data or interpretations transformed by at least one of the age mapping volume and the depth mapping volume are outputted.
