Abstract
A downhole tool for a wellbore within a geological formation may include a housing to be lowered into the wellbore, a probe carried by the housing, and a packer carried by the probe. The packer may include a rigid base, an elastomeric member carried by the 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. The rigid base, the elastomeric member, and the support member may each have respective aligned openings therein defining a fluid sampling inlet.

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.
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.
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.
