Abstract
Systems and methods for downhole formation testing based on the use of one or more elongated sealing pads disposed in various orientations capable of sealing off and collecting or injecting fluids from elongated portions along the surface of a borehole. The various orientations and amount of extension of each sealing pad can increase the flow area by collecting fluids from an extended portion along the surface of a wellbore, which is likely to straddle one or more layers in laminated or fractured formations. 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.
