Packer Tool Including Multiple Ports

A method of accessing formation fluid within a wellbore including a wall, the method comprising:

• forming an interval within the wellbore by expanding a first packer and a second packer of a tool to abut the wellbore wall, the tool comprising a packer port and an interval port;
• changing a state of one of the packer port and the interval port of the tool;
• measuring a change in pressure of fluid flow received into the tool based upon the change of state of the one of the packer port and the interval port of the tool;
• and
• determining whether to change the state of the one of the packer port and the interval port of the tool based upon the measured change in pressure of fluid flow received in the tool.

A system to access formation fluid within a wellbore including a wall, the wellbore extending through a formation including formation fluid, the system comprising:

• a first expandable packer including a packer port positioned upon the first expandable packer, the packer port in fluid communication with a flow path of the tool;
• a second expandable packer spaced from the first expandable packer;
• a mandrel extending between the first expandable packer and the second expandable packer, the mandrel including an interval port in fluid communication with the flow path of the tool;
• a valve operably coupled to the flow path to selectively enable fluid flow through one of the packer port and the interval port;
• a pressure gauge operably coupled to the flow path to measure pressure of fluid flow through one of the packer port and the interval port;
• and
• a controller to control an operation of the valve based on a measured pressure of fluid flow through one of the packer port and the interval port from the pressure gauge.
