Subdivision of each sea level cycle into its depositional phases helps us construct high-frequency paleogeographic maps, one or more for each depositional systems tract. These maps help us predict reservoir and seal rock as well as delineate probable migration avenues. From integrated data sets, a high-resolution age model can be constructed and used to correlate and calibrate depositional sequences. Using the age model and stratigraphic thicknesses, rock accumulation rates of each cycle can be calculated and the thermal history for each depocenter reconstructed.
Subsection 1 of this section focuses on sea level cycle phase. Subsection 2 focuses on the use of paleogeography in petroleum exploration.
