AbstractSabine Peninsula of Melville Island was the subject of an oil and gas exploration boom from 1961 to 1985, during which time seismic-reflection data were collected and wells were drilled. As a result, the two largest conventional natural gas fields in Canada were discovered. Seismic-reflection methods use sound waves to image the internal structure of the Earth. Waves are emitted at the surface before being reflected back to the surface by geological interfaces and recorded. Modern analysis methods were used to reinvestigate existing seismic data. In doing so, eight seismic unit boundaries identified on seismic profiles in two-way traveltime were correlated to the regional geological framework and gridded to provide subsurface maps. Each map approximates the structures preserved at that particular time or depth allowing the enhancement of the geological knowledge of Sabine Peninsula and better delimitation of elements of the petroleum systems therein.

In doing so, eight seismic unit boundaries identified on seismic profiles in two-way travel time were correlated to the regional geologic framework and gridded to provide subsurface maps. Each map approximates the structures preserved at that particular time or depth allowing us to enhance the geological knowledge of Sabine Peninsula and better delimit elements of the petroleum systems therein.
