Downhole tool fluid flow control apparatus including a first fluid valve between a first portion of a first flowline and a second portion of a second flowline. The first and second flowlines are adjacent each other. A second fluid valve is between a second portion of the first flowline and a first portion of the second flowline. The first and second fluid valves are controllable to cause fluid flow between the first portion of the first flowline and the second portion of the second flowline or between the first portion of the second flowline and the second portion of the first flowline.

Fluid control modules for use with downhole tools

An apparatus includes a downhole tool for conveyance in a wellbore extending into a subterranean formation. The downhole tool includes a focused sampling probe that includes a piston movable between an open position and a closed position, an auxiliary filter coupled to the piston, and a scraper that interfaces with the auxiliary filter. Movement of the piston may cause the auxiliary filter to move against the scraper.

Auxiliary flow line filter for sampling probe

An apparatus for testing a subterranean formation penetrated by a wellbore, comprising a tool having a sample flow line an inlet disposed with the tool and configured to establish fluid communication between the formation and the sample flow line to draw a fluid sample into the sample flow line, and an active filter positioned in the sample flow line and providing a filter flow route and a bypass flow route in the sample flow line.
