ProgramSverdrup Sedimentary Basin, GEM: Geo-mapping for Energy and Minerals
Released2012 03 27
AbstractThe study of the Sabine Peninsula, western Arctic Islands, was undertaken as part of the Government of Canada's Geo-mapping for Energy and Minerals (GEM) program. Given the cost of data acquisition in frontier areas, vintage data sets still possess a strong value. This study utilizes modern geoscientific processing and interpretation methods applied to a suite of data collected during the initial round of exploration that took place between the late 1960s and early 1980s. The focus of this project is to map the subsurface of Sabine Peninsula and provide a more detailed seismic stratigraphy to ultimately develop play concepts that were not identified during the initial round of exploration.
Following the reprocessing of the seismic data sets, six time-structure maps of the Triassic through Cretaceous succession of the Sverdrup Basin (<3 s) display changes in the morphology of the horizons throughout the Mesozoic. Several features are preserved throughout the Mesozoic section, for instance, the presence of a linear flexure inherited from the deeper section (possibly Permian) indicates the loca-tion of a possible paleoshelf edge. Additionally, the presence of a depression, and the gradual infill of that depression provide clues as to what type of seismic successions can be expected in the deeper section and the adjacent offshore.
