New pre-production well test for analysis of multilayered commingled reservoirs withy unequal initial pressures Conference Paper uri icon


  • The main objective of this paper is to design a new well test that will enble us to determine the inidividual layer properties (layer permeability, layer porosity, layer diffusivity and layer skin) early inh the life of the reservoir impact of well testing. The pr-production well test is a well test that is carried early in the life of the reservoirs when the information is most needed for planning production schedule and economic decisions concerning the life of wells. In this paper we have developed a general mathematical solution to model the reservoir performance of commingled reservoirs with unequal initial pressures in Laplace space.
