Preparation of contour maps for pertinent diagenetic components may assist in the evaluation of zone continuity (see [[Subsurface maps]]). However, the merging of data from more than one diagenetic zone may lead to misinterpretations of the degree of continuity present. Contour maps should always be interpreted in combination with detailed correlation [[cross section]]s. Preparation of three-dimensional “spectragrams” may be helpful in visual correlation studies.

Depending on the objectives of the study being conducted, the geologist needs to generate additional maps, [[cross section]]s, fence diagrams, or simulation models. For the purposes of reserve estimation, net pay maps are needed (see [[Effective pay determination]]). If the major controls on net pay distribution are diagenetic in nature, contouring of net pay maps should be guided by trends present on contour maps of major diagenetic components. Average porosity maps should also be “guided” in this same fashion. Where simulation of fluid flow behavior is the object of the study, the geologist must assist in the preparation of a three-dimensional simulation model.
