FORMATION TESTING AND SAMPLING APPARATUS AND METHODS

Document Type and Number:

WIPO Patent Application WO2004081334

Kind Code:

A3

Abstract:

Systems and methods for downhole formation testing. The invention is based on the use of one or more elongated sealing pads (34) capable of sealing off and collecting or injecting fluids from elongated portions along the surface of a borehole. The modified probe pads (34) of a device (30) 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.
