==Purpose and procedure==
==Purpose and procedure==
The purpose of a facies map is to reconstruct paleogeography, from which we can predict reservoir, seal, and source-rock distribution. Facies maps are made at an isochronous surface or within a coeval interval.<ref name=ch04r94>Tearpock, D., J., Bischke, R., E., 1991, Applied Subsurface Geologic Mapping: Prentice-Hall, 648 p.</ref><ref name=ch04r107>Visher, G., S., 1984, Exploration Stratigraphy: Tulsa, PennWell Books, 334 p.</ref> We map reservoir system thickness (1) to compare the distribution of reservoir-system thickness and field location and (2) to identify or predict locations with thick reservoirs and trapping conditions that are undrilled. A procedure for mapping facies is outlined in the table below.
