Abstract:
1. A tool for determining the ratio of relative permeability of downhole fluids obtained from a downhole formation, comprising: a probe module that includes a flow line; a pumpout module operatively coupled to said flow line; a downhole fluid analysis module configured to measure a viscosity and a flow rate of a first formation fluid and a second formation fluid; a calculator module configured to calculate a ratio of relative permeabilities of said first formation fluid and said second formation fluid; and a separator to separate said first formation fluid from said second formation fluid, wherein said calculator module calculates said ratio by dividing a product of said flow rate and said viscosity of said first fluid with a product of said flow rate and said viscosity of said second fluid to obtain a ratio of the relative permeability of said first fluid to that of said second fluid.
