Abstract

A method for layered reservoirs without crossflow in order to estimate individual layer permeabilities and skin factors is disclosed. The method consists of two sequential drawdown tests. During these tests the wellbore pressure and the sandface flow must be measured simultaneously. The permeability and skin factor for each layer are estimated uniquely using measured wellbore pressure and sandface flow rate from these two drawdown tests.
