First Claim
Patent Images
1. A tool to be used within a wellbore, the wellbore including a wall and extending in a formation with formation fluid, comprising:
- a packer expandable against the wellbore wall;
ports included within the packer to enable formation fluid to flow into the tool from the formation;
the ports being arranged in a first port configuration optimized based upon a first predetermined formation property; and
a second port configuration, wherein;
the ports are switchable between the first port configuration and the second port configuration; and
the second port configuration is optimized based upon a second predetermined formation property.

11. A method to collect fluid within a wellbore, the wellbore including a wall and extending in a formation with formation fluid, the method comprising:
-
selecting a first port configuration for ports positioned on a packer optimized based upon a first predetermined formation property; expanding the packer against the wellbore wall; receiving formation fluid from the formation into the tool through the ports; selecting a second port configuration optimized based upon a second formation property; and switching between the first port configuration and the second portion configuration. - View Dependent Claims (12, 13, 14, 15)

16. A packer to be used within a wellbore, the wellbore including a wall and extending in a formation with formation fluid, the packer comprising:
-
ports comprising a sample port to sample formation fluid from the formation and a guard port to guard the sample port from contamination, the ports included within the packer to enable formation fluid to flow into the tool from the formation; the ports being arranged in a first port configuration optimized based upon a first ratio of permeability for the formation in a first direction to permeability for the formation in a second direction; and a second port configuration, wherein; the ports are switchable between the first port configuration and the second port configuration; the second port configuration is optimized based upon a second ratio of the permeability for the formation in the first direction to the permeability for the formation in the second direction. - View Dependent Claims (17)
