The following exercise will guide you through the process of constructing a sequence-stratigraphic framework of a hydrocarbon-bearing, sandstone-and-shale interval. You will correlate key sequence-stratigraphic surfaces using well log curves from a five-well cross section. In the process of doing so, you will also define the systems tracts that compose the interval.
