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;
- and
- the ports being arranged in a first port configuration optimized based upon a first predetermined formation property.
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;
- and
- receiving formation fluid from the formation into the tool through the ports.
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.
