BOREHOLE TESTER APPARATUS AND METHODS USING DUAL FLOW LINES

摘要

A formation tester system with a tester tool comprising two or more functionally configured flow lines. The two or more functionally connected flow lines cooperating with one or more pumps and cooperating valves direct fluid to and from various axially disposed sections of the tester tool for analysis, sampling, and optionally ejection into the borehole or into the formation. The functionally connected flow lines extend contiguously through the sections of the tester tool. The functionally configured flow lines, cooperating with the one or more pumps and valves, can also direct fluid to and from various elements within a given tester tool section. Manipulation of fluid flows within the tester tool, as well as analysis, sampling and/or ejection operations, can be varied with the tester tool disposed in the borehole using appropriate commands from the surface of the earth.
