FORMATION TESTING AND SAMPLING APPARATUS AND METHODS
摘要
Systems and methods for downhole formation testing. The invention is 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 probe pads of a device made in accordance with the invention 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 is capable of fast deployment and withdrawal to speed up the measurement cycles. 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.
