Abstract:
A fluid squeeze monitor downhole tool and a method of monitoring formation squeeze features a tool body that can be placed downhole at a desired elevational location to produce a controlled, localized reduction of pressure head and measure the resultant inward displacement of the borehole wall. The reduction in head is accomplished by draining the fluid in a bladder (or collapsible container) located on the tool body into a reservoir "sump" that is incorporated into the downhole tool.
