Abstract

See full text

A formation tester tool assembly includes a seal member mounted on rigid stabilizer that contacts a borehole wall separately from the seal member, so that seal exposure to a stabilization load that presses the tool against the borehole wall is limited or reduced by contact engagement of the stabilizer with the borehole wall. The stabilizer is provided by a hydraulically actuated probe piston reciprocally movable relative to a tool body on which it is mounted. The seal member is in some embodiments movable relative to the probe piston, for example being configured for hydraulic actuation to sealingly engage the borehole wall while the tool body is stabilized by action of the probe piston.
