Packer including support member with rigid segments

1. A downhole tool for a wellbore within a geological formation comprising:

a housing to be lowered into the wellbore;

a probe carried by said housing; and

a packer carried by said probe and comprising

a rigid base,

an elastomeric member carried by said rigid base and having a recess therein, and

a support member within the recess and comprising a plurality of rigid segments interconnected to allow relative movement between adjacent rigid segments,

said rigid base, said elastomeric member, and said support member each having respective aligned openings therein defining a fluid sampling inlet.

2. The downhole tool of claim 1 wherein said plurality of rigid segments comprise mating hinge portions.

3. The downhole tool of claim 2 wherein said plurality of mating hinge portions comprise respective mating male and female key portions.

4. The downhole tool of claim 1 further comprising at least one elongate member interconnecting said plurality of rigid segments.

5. The downhole tool of claim 1 wherein said support member has a recessed medial portion and raised sidewall portions surrounding said recessed medial portion.

6. The downhole tool of claim 1 wherein said elastomeric member has an oval shape.

7. The downhole tool of claim 1 wherein said support member has an elongate shape.

8. The downhole tool of claim 1 wherein said support member has a circular shape.

9. A packer to be carried by a probe on a downhole tool for use within a wellbore in a geological formation, the packer comprising:

a rigid base to be carried by the probe;

an elastomeric member carried by said rigid base and having a recess therein; and

a support member within the recess and comprising a plurality of rigid segments interconnected to allow relative movement between adjacent rigid segments;

said rigid base, said elastomeric member, and said support member each having respective aligned openings therein defining a fluid sampling inlet.

10. The packer of claim 9 wherein said plurality of rigid segments comprise mating hinge portions.

11. The packer of claim 10 wherein said plurality of mating hinge portions comprise respective mating male and female key portions.

12. The packer of claim 9 further comprising at least one elongate member interconnecting said plurality of rigid segments.

13. The packer of claim 9 wherein said support member has a recessed medial portion and raised sidewall portions surrounding said recessed medial portion.

14. The packer of claim 9 wherein said elastomeric member has an oval shape.

15. The packer of claim 9 wherein said support member has an elongate shape.

16. The packer of claim 9 wherein said support member has a circular shape.

17. A method for making a packer to be carried by a probe on a downhole tool for use within a wellbore in a geological formation, the method comprising:

arranging a rigid base, an elastomeric member, and a support member so that the elastomeric member is carried by the rigid base and the support member is carried within a recess of the elastomeric member;

the support member comprising a plurality of rigid segments interconnected to allow relative movement between adjacent rigid segments;

the rigid base, the elastomeric member, and the support member each having respective aligned openings therein defining a fluid sampling inlet.

18. The method of claim 17 wherein the plurality of rigid segments comprise mating hinge portions.

19. The method of claim 18 wherein the plurality of mating hinge portions comprise respective mating male and female key portions.

20. The method of claim 17 further comprising interconnecting the plurality of rigid segments with at least one elongate member.
