Computational modeling of multi-layered reservoirs with unequal initial pressures-development of a new pre-production well test

摘要

The objective of this paper is to present a description and verification of a new semi-analytical simulator used to model the wellbore performance of multi-layered reservoirs with unequal initial pressures. The semi-analytical simulator proved to be faster than a conventional three-dimensional, finite-difference commercial simulator. Also the amount of information needed to run the model is much reduced. The semi-analytical simulator allows each layer to have different layer properties, different boundary conditions, and different initial pressures.
