Abstract: A method can include accessing a seismic data file for a seismic survey defined in part by a bin grid, where seismic data in the seismic data file are organized according to a data structure that includes headers and seismic trace data; performing an assessment of orthogonality of the bin grid of the seismic data file; responsive to detection of an orthogonality issue by the assessment, determining an orthogonal bin grid; extracting a trace header template using at least one of one or more introductory headers, where the trace header template specifies at least trace locations; performing a validation operation for validation of the trace header template; and, responsive to validation of the trace header template, outputting metadata that comports with the orthogonal bin grid and the validated trace header template for loading of the seismic data file to a data storage system.

Abstract: Apparatus and methods for hydrocarbon reservoir characterization and recovery including collecting geological data relating to a subteranean formation, forming initial parameters using the data, performing a pricipal component analysis of the parameters to create a model, and performing history matching using the model. In some embodiments, the principal component analysis is linear principal component analysis or kernal principal component analysis.
