Abstract:
1. A method for performing chrono-stratigraphic interpretation of a subterranean formation, comprising: obtaining a seismic volume comprising a plurality of stratigraphic features of the subterranean formation, wherein the plurality of stratigraphic features are deformed by a plurality of structural events; performing, by a processor of a computer system, a structural restoration of the seismic volume to generate a restored seismic volume by removing deformation due to the plurality of structural events, wherein the restored seismic volume comprises a plurality of restored stratigraphic features; performing, using the processor, a chrono-stratigraphic interpretation based on the restored seismic volume to generate a plurality of chrono-stratigraphic objects each associated with a respective relative geologic age; identifying a borehole penetrating a first portion of the subterranean formation, the first portion corresponding to the seismic volume; obtaining a borehole geology interpretation of the borehole comprising an interpreted borehole feature; identifying a first absolute geologic age of the interpreted borehole feature based on a corresponding core sample; identifying a stratigraphic feature of the plurality of stratigraphic features as corresponding to the interpreted borehole feature by comparing the borehole geology interpretation and the seismic volume; identifying a chrono-stratigraphic object of the plurality of chrono-stratigraphic objects as corresponding to the stratigraphic feature based on the correlation; determining a second absolute geologic age of the chrono-stratigraphic object based on the first absolute geologic age of the interpreted borehole feature; and displaying the plurality of chrono-stratigraphic objects in a chrono-stratigraphic space according to the respective relative geologic age of each of the plurality of stratigraphic objects.
