DOWNHOLE TOOL WITH CAPILLARY BIASING SYSTEM

摘要

A downhole tool and capillary biasing system includes a housing (20); an intrusion fluid (18) contained within a portion of the housing; a capillary biasing member (12) in fluid contact with the intrusion fluid; and a pressure application configuration capable of pressurizing the intrusion fluid within the housing and method. The intrusion fluid may be a non-wetting fluid and the capillary biasing member a porous matrix.
