Abstract
A snorkel and pad for use with a formation testing tool is formed with a cylindrical geometry at the interface where the snorkel and pad contacts the inner surface of a borehole. The cylindrical geometry reduces or eliminates gaps that a flat interface surface would leave between the snorkel and the inner surface of the borehole, reducing the possibility that a surrounding pad could extrude through the gap. The snorkel is prevented from rotating during operation, ensuring the correct orientation of the cylindrical geometry interface surface relative to the inner surface of the borehole. The snorkel may be used as part of a formation testing system.
