Paleontology, the study of fossil organisms and their traces, has been used in the exploration for and exploitation of hydrocarbons since the later half of the nineteenth century. Because fossil assemblages change through time, they aid in the prediction of depth to reservoirs, to casing points, and to overpressured zones. Chronostratigraphic assemblages are the basis for correlating strata among wells, across basins, and between basins. Correlation is the method for predicting the lateral continuity and physical and chronostratigraphic equivalency of strata. Fossil assemblages are also evidence of the depositional environments of the drilled strata and thus play a role in predicting the location of reservoirs, source rocks, and pinch-out of porous strata.
