Abstract

A tool to be used within a wellbore including a wall, the wellbore extending through a formation including formation fluid, includes a first packer and a second packer. The first packer includes a packer port to enable formation fluid flow through the first packer, with the second packer spaced from the first packer. The first packer and the second packer are expandable to abut the wellbore wall to form an interval within the wellbore between the first packer and the second packer, in which the tool further includes an interval port in fluid communication with the interval.

First claim

What is claimed is:

1. A tool to be used within a wellbore including a wall, the wellbore extending through a formation including formation fluid, the tool comprising:
a first packer including a packer port to enable formation fluid flow through the first packer, wherein the packer port abuts the wellbore wall when the first packer is expanded;
a second packer spaced from the first packer;
the first packer and the second packer being expandable to abut the wellbore wall to form an interval within the wellbore between the first packer and the second packer; and
an interval port in fluid communication with the interval.

2. The tool of claim 1 , further comprising:
a mandrel extending between the first packer and the second packer, the mandrel including the interval port to enable formation fluid flow through the mandrel.

3. The tool of claim 1 , wherein the second packer includes a second packer port to enable formation fluid flow through the second packer.

4. The tool of claim 1 , further comprising:
a third packer spaced from the first packer and expandable to abut the wellbore wall to form a second interval within the wellbore; and
a second interval port in fluid communication with the second interval.

5. The tool of claim 4 , further comprising:
a mandrel extending between the first packer and the third packer, the mandrel including the second interval port to enable formation fluid flow through the mandrel.

6. The tool of claim 4 , wherein the third packer includes a third packer port to enable formation fluid flow through the third packer.

7. The tool of claim 1 , further comprising:
a flow path formed through the tool;
wherein the packer port and the interval port are in fluid communication with the flow path.

8. The tool of claim 7 , wherein the flow path comprises a packer flow path and an interval flow path, wherein the packer port is in fluid communication with the packer flow path, and wherein the interval port is in fluid communication with the interval flow path.

9. The tool of claim 8 , wherein the packer flow path and the interval flow path are in selective fluid communication with each other.

10. The tool of claim 1 , further comprising one of:
a packer port valve to selectively enable formation fluid flow through the packer port; and
an interval port valve to selectively enable formation fluid flow through the interval port.

11. The tool of claim 1 , further comprising one of:
a pressure gauge to measure pressure of formation fluid flowing through at least one of the packer port and the interval port; and
a sensor positioned on the first packer to measure a property of the formation fluid.

12. 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 on at least one of the first packer or the second packer and an interval port, wherein the packer port abuts the wellbore wall when the packer is expanded;
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.

13. The method of claim 12 , wherein changing the state comprises:
enabling fluid flow through the one of the packer port and the interval port.

14. The method of claim 13 , wherein determining whether to change the state comprises:
enabling fluid flow through the one of the packer port and the interval port of the tool if the measured change in pressure of fluid flow received in the tool is at or above a predetermined amount; and
preventing fluid flow through the one of the packer port and the interval port of the tool if the measured change in pressure of fluid flow received in the tool is below the predetermined amount.

15. The method of claim 12 , wherein changing the state comprises:
preventing fluid flow through the one of the packer port and the interval port.

16. The method of claim 15 , wherein determining whether to change the state comprises:
enabling fluid flow through the one of the packer port and the interval port of the tool if the measured change in pressure of fluid flow received in the tool is at or above a predetermined amount; and
preventing fluid flow through the one of the packer port and the interval port of the tool if the measured change in pressure of fluid flow received in the tool is below the predetermined amount.

17. The method of claim 12 , further comprising:
changing a state of the other 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 other of the packer port and the interval port of the tool; and
determining whether to change the state of the other 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.

18. The method of claim 12 , wherein the packer port comprises a plurality of packer ports and the interval port comprises a plurality of interval ports, the method further comprising:
changing a state of the plurality of packer ports;
measuring a change in pressure of fluid flow received into the tool based upon the change of state of the plurality of packer ports;
determining whether to change the state of the plurality of packer ports of the tool based upon the measured change in pressure of fluid flow received in the tool;
changing a state of the plurality of interval ports;
measuring a change in pressure of fluid flow received into the tool based upon the change of state of the plurality of interval ports;
determining whether to change the state of the plurality of interval ports of the tool based upon the measured change in pressure of fluid flow received in the tool.

19. 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, wherein the packer port is in fluid communication with a flow path of the tool and the packer port abuts the wellbore wall when the first packer is expanded;
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.

20. The system of claim 19 , wherein:
the flow path comprises a packer flow path and an interval flow path;
the valve comprises a packer valve and an interval valve;
the packer port is in fluid communication with the packer flow path;
