Claim Text:
1. A method comprising: positioning a formation testing tool within a wellbore formed within a subsurface reservoir, wherein the formation testing tool comprises a first pair of opposite drains disposed on diametrically opposite sides of the formation testing tool and a second pair of opposite drains disposed on diametrically opposite sides of the formation testing tool different from the diametrically opposite sides of the first pair of opposite drains, and the first and second pairs of opposite drains are disposed around a periphery of the formation testing tool; sensing a first set of pressure values versus time at both the first and second pairs of opposite drains during a first test; sensing a second set pressure values versus time at only the first pair of opposite drains during a second test; and sensing a third set of pressure values versus time at only the second pair of opposite drains during a third test.
