Systems and methods for downhole formation testing based on the use of one or more elongated sealing pads capable of sealing off and collecting or injecting fluids from elongated portions along the surface of a borehole. The modified sealing pads increase the flow area by collecting fluids from an extended portion along the surface of a borehole, which is likely to straddle one or more layers in laminated or fractured formations. A tester device using the elongated sealing pads can be deployed and withdrawn using an extendible element pressing the pads to the borehole. Various designs and arrangements for use with a fluid tester, which may be part of a modular fluid tool, are disclosed in accordance with different embodiments.
A method of operating in a borehole a formation tester having a rigid base attached to an elongated sealing pad, the elongated sealing pad having an elongated recess and a rigid plate installed in the elongated recess, the rigid plate having an edge embedded into the elongated sealing pad and a flange some distance away from the edge, the method comprising:
