US 2017/0370216 A1 · MULTI-PROBE RESERVOIR SAMPLING DEVICE

Abstract

A tool insertable into a wellbore for sampling formation fluids includes a body, and sample probe assemblies that project radially outward from the body and into sampling contact with the wellbore wall. Packers are provided on the outer terminal ends of the sample probe assemblies and which are urged against the wellbore wall. Actuator driven linkage assemblies selectively deploy and retract the packers from and back into the body. The sample probe assemblies are disposed at substantially the same axial location on the body, and are angularly spaced about an axis of the body. Each sample probe assembly is independently actuated, so that a discrete azimuthal portion can be sampled, and each has a dedicated sample container for storing sampled formation fluid.

Dependent claims

A downhole tool for sampling formation fluid in a wellbore comprising:

a body;
articulated linkage assemblies, each of which having an end coupled with the body, and each of which selectively and independent from one another move between a stowed position to a deployed position;
pad assemblies on ends of the linkage assemblies that are distal from the ends that are coupled to the body and that are at substantially the same depth in the wellbore when the linkage assemblies are in the deployed position;
and
ports on the pad assemblies that are in selective communication with formation fluid in a formation that is intersected by the wellbore when the linkage assemblies are in the deployed position.
