Modeling technique adds reservoir geometry to decline curves

A method that is consistent with the physical understanding of the reservoir can be used to project production rate as a function of time.This method requires only some readily available information. Of course, more detailed field information should be included, whenever possible, to increase confidence in the model.Incorporated in the model are some simplifying assumptions, and it has limitations, as does any mathematical representation.
