Title:
METHOD TO CHARACTERIZE UNDERGROUND FORMATION
Document Type and Number:
WIPO Patent Application WO/2012/087797
Kind Code:
A3
Abstract:
A method for determining a characteristic of an underground formation with a fluid is described. The method includes providing a sample material of the underground formation; measuring the permeability and the porosity of the sample material; performing a drainage test on the sample material using the fluid; estimating the threshold pressure of the sample material from the drainage test, the permeability and the porosity measurements; and determining the receding contact angle of the fluid on the sample material from the threshold pressure. The sample material can be disaggregated material.
