Scope: Determination of water-oil relative permeability of a plug using Unsteady State Method 

 

Relative permeability is the ratio of the effective permeability of a fluid to the absolute permeability of the rock that is an indication of motion ability of the fluid in the presence of another fluid in a porous medium. It is totally affiliated to saturation level.

Experiment Description

 

 

Water (or oil) is injected at a suitable pressure (or flow rate) to the plug, which is saturated with oil (or water). By measuring the necessary parameters, water-oil relative permeability curves can be obtained for imbibition or drainage utiliz­ing analytical (JBN, JR & etc.) or numerical (history matching) methods.
