The terms isopach and isopach map are incorrectly used interchangeably to describe isochores and isochore maps. Isopachs and isochores are equivalent only. Commonly, the isopachs, or contours that make up an isopach map, display the See: contour, contour interval, contour map, formation, isochore, reservoir. true vertical thickness is an isochore map. Note that in common practice, isochore maps are informally referred to as “isopach” maps.

Isochore and Isopach Maps – Applied Subsurface Geological Mapping [Book]
Sedimentary beds may show lateral changes in thickness, either in connection with an erosional episode that created an unconformity or due to lateral facies changes.
It is very crucial for the hydrocarbon industries to document the lateral changes in the layer thickness.
They represent thickness variations and thickness trends of a given unit. Vertical thickness increased with increasing dip angle and when dip japs is zero the true thickness and vertical thickness are equal.
