A Comparison of Relative Permeability from Centrifuging Versus Coreflooding
Abstract/Contents
- Abstract
- Laboratory measurement of relative permeability has traditionally taken place using unsteady state coreflood tests. Procedures also exist for deriving relative permeabilities from centrifuge data, but the shapes of the curves can be different than those from coreflooding. This research compares coreflood relative permeabilities versus centrifuge relative permeabilities by obtaining coreflood and centrifuge data from the same piece of Berea sandstone for gas/oil and oil/water systems. A one dimensional coreflood/centrifuge model, a least squares history matching algorithm, and the Corey relationships are used to match the experimental data. Core data is also analyzed using the standard Jones-Roszelle technique. Centrifuge data was analyzed using the model proposed by Hagoort. Jones-Roszelle and Hagoort relative permeability curves are then compared with the Corey curves that were obtained from simulation history matching.Comparison of the two sets of relative permeability curves from centrifuging versus coreflooding for the oil/water system displayed similar shapes and endpoints for the wetting phase, but showed different shapes and endpoints for the nonwetting phase.
