 Firstly, depositional regimes – although actually controlled by numerous other factors – are primarily linked to water-depth. Knowledge of the particular depositional regime (e.g. fluvial or turbiditic) of the reservoir may fundamentally affect the way that reservoir is developed and exploited. The internal reservoir architecture can be better defined and internal connectivity pathways can be better predicted.
-Secondly, the EOD is valuable to estimate accommodation space which is, in turn, input into basin modelling scenarios which impacts on maturity studies.
+Secondly, maps showing EOD (sometimes called Gross Depositional Environment - GDE - Maps) are vital in basin-screening to identify prospective new play types.
-Thirdly, knowledge of the EOD can greatly assist in solving problems of correlation, particularly between proximal and distal depositional settings.

 Traditionally, geologists use the following sources of information to determine paleoenvironments:
