Abstract

Multiple wires run parallel to one another. Each of wires is spaced apart from each adjacent wire at a distance less than a width of an encased microchip. Each of the plurality of wires includes a plurality of straight segments in a plane and bent segments that connect two of the plurality of straight segments. For each of the wires, each bent segments includes a first end, a second end, and a curved portion curved away from the plane. The first end is connected to at least one of the straight segments and separated from the second end a distance greater than the width of the encased microchip. The curved portion includes a diameter greater than the width of the encased microchip.

First claim

What is claimed is:

1. A wellbore system comprising:
a wellbore formed into a geologic formation;
a circulation pump configured to circulate fluid through the wellbore;
a shaker table configured to separate wellbore cuttings from a circulation fluid;
a plurality of encapsulated microchips configured to be circulated through the wellbore with the circulation fluid;
a screen comprising:
a plurality of wires running parallel, each of the plurality of wires is spaced apart from each adjacent wire at a distance less than a width of an encased microchip, and each of the plurality of wires includes a plurality of straight segments in a plane and a plurality bent segments connecting a plurality of straight sections, at least one of the plurality of bent segments of each wire being positioned between two straight segments of the same wire; and
for each of the plurality of the wires, each bent segments in the plurality of segments includes a first end, a second end, and a curved portion curved away from the plane, the first end connected to at least one of the plurality of straight sections and separated from the second end a distance greater than the width of the encased microchip, and the curved portion includes a diameter greater than the width of the encased microchip;

a screen mount configured to secure the screen from at least three sides of the screen; and
an obstacle positioned above the screen, the obstacle configured to prevent a microchip from bouncing out of the curved portions.

2. The wellbore system of claim 1 , wherein the screen is mounted in the shaker table.

3. The wellbore system of claim 1 , wherein the encased microchips are a first set of encased microchips and the screen is a first screen, the system further comprising a second screen with traps configured to catch a second plurality of encased microchips that are a different size than the first set of encased microchips.

4. The wellbore system of claim 1 , wherein the screen is mounted between 10° and 75° from horizontal when in use.

5. The wellbore system of claim 1 , wherein each of the curved portions is configured to extend in a downward direction when in use.

6. The wellbore system of claim 1 , wherein the screen is positioned downstream of a shaker table.
