14. A method comprising:
locating a formation tester tool having tool body in a borehole defined by a borehole wall;
moving a stabilizer mounted on the tool body for transverse movement between a retracted position and a deployed position in which a contact surface of the stabilizer forcibly engages the borehole wall and an outer periphery of a housing of the tool body contacts the borehole wall diametrically opposite the contact surface of the stabilizer, wherein an active seal carried by the stabilizer is wholly retracted within the stabilizer when the stabilizer is in the retracted position so that the contact surface of the stabilizer is located radially beyond the seal;
while the stabilizer is in the deployed position, causing the active seal to sealingly engage the borehole wall at a sealing surface spaced from the contact surface of the stabilizer, thereby to define a sealed isolation zone isolated from borehole fluids; and
testing one or more formation properties by exposing a testing mechanism forming part of the tool to the isolation zone.
