Determination of relative phase permeabilities in three-phase saturation region on the core samples of Yu11 layer of Shinginskoye field

Authors: V.T. Pitkevich, G.V. Lozhkin, E.V. Moreva, I.I. Zubarev, A.V. Morev (SibNIINP OAO, Tyumen, Russian Federation), I.G. Kashapov (Gazpromneft-Vostok LLC, Tomsk, Russian Federation)

Filtration tests, based on the algorithm, proposed by authors previously, are executed on core samples taken from the Yu11 layer of Shinginskoye field, for which the relative phase permeabilities were determined by stationary filtration method (OST 39-235-89) in the system oil - water at zero gas saturation, in the system oil - gas at irreducible water saturation and in the system water-gas at the minimal oil saturation. On the basis of experimental data, the analytical functions of the surfaces of relative phase permeabilities for oil, gas and water in the region of a real three-phase saturation.

Key words: relative permeabilities, three-phase saturation, and core sample
