Abstract

Embodiments provide an expandable meshed component for guiding an untethered measurement device used in a subterranean well. The expandable meshed component includes an uphole radial portion, an intermediate radial portion, a downhole radial portion, an outer meshed wall, and an inner meshed wall. The expandable meshed component has a density less than a fluidic component occupying the space. A method for guiding an untethered measurement device used in a subterranean well includes deploying a compressed expandable meshed component tethered to the untethered measurement device, disconnecting the compressed expandable meshed component and the untethered measurement device, and releasing a sleeve surrounding the compressed expandable meshed component such that the expandable meshed component expands, ascends, and fits into an annulus.

First claim

What is claimed is:

1 . An expandable meshed component for guiding an untethered measurement device used in a subterranean well ascending from a space provided by a wellbore wall and a terminus of a casing, the expandable meshed component, in an expanded configuration, comprising:
an uphole radial portion; an intermediate radial portion, the intermediate radial portion having an outer diameter less than an inner diameter of the uphole radial portion, the intermediate radial portion having an inner diameter less than an outer diameter of the casing; a downhole radial portion, the downhole radial portion having an outer diameter greater than an outer diameter of the uphole radial portion; an outer meshed wall; and an inner meshed wall, wherein the expandable meshed component has a density less than a fluidic component occupying the space.

2 . The expandable meshed component of claim 1 , wherein a radial gap between the outer diameter of the downhole radial portion and a diameter of the wellbore wall is less than a diameter of the untethered measurement device.

3 . The expandable meshed component of claim 1 , wherein the uphole radial portion comprises at least two concentric rings, wherein each pair of adjacent concentric rings are radially connected by a plurality of connecting components.

4 . The expandable meshed component of claim 3 , wherein each of the plurality of connecting components has a jagged configuration capable of shrinking in the radial direction.

5 . The expandable meshed component of claim 1 , wherein the intermediate radial portion comprises at least two concentric rings, wherein each pair of adjacent concentric rings are radially connected by a plurality of connecting components.

6 . The expandable meshed component of claim 5 , wherein each of the plurality of connecting components has a jagged configuration capable of shrinking in the radial direction.

7 . The expandable meshed component of claim 1 , wherein the downhole radial portion comprises at least two concentric rings, wherein each pair of adjacent concentric rings are radially connected by a plurality of connecting components.

8 . The expandable meshed component of claim 7 , wherein each of the plurality of connecting components has a jagged configuration capable of shrinking in the radial direction.

9 . The expandable meshed component of claim 1 , wherein the expandable meshed component is configured to transition from the expanded configuration to a compressed configuration, the compressed configuration having an outer diameter less than an inner diameter of the casing.

10 . The expandable meshed component of claim 9 , further comprising:
a sleeve, the sleeve surrounding a radially exterior surface of the expandable meshed component in the compressed configuration, the sleeve having a diameter less than the inner diameter of the casing; and a releasable member, the releasable member configured to allow release of the sleeve such that the expandable meshed component transitions from the compressed configuration to the expanded configuration.

11 . A method for guiding an untethered measurement device used in a subterranean well ascending from a space provided by a wellbore wall and a terminus of a casing, the method comprising the steps of:
deploying an expandable meshed component tethered to the untethered measurement device via a tethering line into the casing, wherein the expandable meshed component is in a compressed configuration, wherein a radially exterior surface of the expandable meshed component is surrounded by a sleeve, wherein the sleeve has a diameter less than an inner diameter of the casing; disconnecting the tethering line as the untethered measurement device exits the casing such that the untethered measurement device is released from the expandable meshed component; and releasing the sleeve as the expandable meshed component exits the casing such that the expandable meshed component transitions from the compressed configuration to an expanded configuration, wherein the expandable meshed component in the expanded configuration ascends and fits into an annulus between the wellbore wall and the casing.

12 . The method of claim 11 , wherein the expandable meshed component has a density less than a fluidic component occupying the space.

13 . The method of claim 11 , wherein a weight is tethered to the untethered measurement device such that the expandable meshed component does not ascend during the deploying step.

14 . The method of claim 11 , wherein the tethering line includes a releasable member, the releasable member allowing the release of the expandable meshed component in the disconnecting step.

15 . The method of claim 14 , wherein the tethering line includes an electromagnetic transducer, the electromagnetic transducer configured to receive electromagnetic waves and convert the electromagnetic waves to electric signals to activate the releasable member allowing the release of the expandable meshed component in the disconnecting step.

16 . The method of claim 15 , wherein the casing includes an electromagnetic transmitter, the electromagnetic transmitter positioned on an exterior surface of the casing at or proximate to the terminus, the electromagnetic transmitter configured to transmit electromagnetic waves received by the electromagnetic transducer of the releasable member.

17 . The method of claim 11 , wherein the expandable meshed component in the expanded configuration comprises:
an uphole radial portion; an intermediate radial portion, the intermediate radial portion having an outer diameter less than an inner diameter of the uphole radial portion, the intermediate radial portion having an inner diameter less than an outer diameter of the casing; a downhole radial portion, the downhole radial portion having an outer diameter greater than an outer diameter of the uphole radial portion; an outer meshed wall; and an inner meshed wall.

18 . The method of claim 17 , wherein the intermediate radial portion is configured to be in contact with a longitudinally exterior surface of the terminus in the releasing step.

19 . A method for measuring properties along a subterranean well, the method comprising the steps of:
deploying an expandable meshed component tethered to the untethered measurement device via a tethering line into the casing, wherein the expandable meshed component is in a compressed configuration, wherein a radially exterior surface of the expandable meshed component is surrounded by a sleeve, wherein the sleeve has a diameter less than an inner diameter of the casing; disconnecting the tethering line as the untethered measurement device exits the casing such that the untethered measurement device is released from the expandable meshed component and the untethered measurement device further descends; releasing the sleeve as the expandable meshed component exits the casing such that the expandable meshed component transitions from the compressed configuration to an expanded configuration, wherein the expandable meshed component in the expanded configuration ascends and fits into an annulus between the wellbore wall and the casing; taking measurements using the untethered measurement device of one selected from the group consisting of: physical properties in the subterranean well, chemical properties in the subterranean well, structural properties in the subterranean well, dynamics of the untethered measurement device, position of the untethered measurement device, and combinat
