Several frequencies, representing different orders of sea level cycles, are superimposed on one another to make a composite sea level cycle curve. For stratigraphic trap exploration, cycles that impact trap location are usually third-, fourth-, and fifth-order sea level cycles. [[:file:exploring-for-stratigraphic-traps_fig21-7.png|Figure 1]] shows how adding third-, fourth-, and fifth-order cycles together will produce a composite curve.
