Abstract
A downhole formation testing and sampling apparatus. The apparatus includes an expandable packer having a radially contracted running configuration and a radially expanded deployed configuration. At least one elongated sealing pad is operably associated with the expandable packer such that operating the expandable packer from the running configuration to the deployed configuration establishes a hydraulic connection between the at least one elongated sealing pad and the formation. The at least one elongated sealing pad has at least one opening establishing fluid communication between the formation and the interior of the apparatus. In addition, the at least one elongated sealing pad has an outer surface operable to seal a region along a surface of the formation to establish the hydraulic connection therewith. The at least one elongated sealing pad further has at least one recess operable to establish fluid flow from the formation to the at least one opening.
