===Cumulative production===

Cumulative oil or gas production is a parameter useful for ultimate reserves forecasts. Cumulative production can also be mapped periodically as a performance indicator signaling areas of the reservoir that may be responding in a manner seemingly unrelated to initial potential. [[:file:subsurface-maps_fig7.png|Figure 7]] shows an example of cumulative production that was concluded to be only poorly correlated to storage capacity (Figure 6) in individual and summed zones of a carbonate reservoir.<ref name=pt06r81 /> In this case, porosity did not necessarily indicate effective porosity.
