Abstract

A sand control screen assembly includes a base pipe, a mesh layer, and a sand screen layer. The base pipe includes a tubular surface and a plurality of perforations formed in the surface. The mesh layer is disposed around the base pipe. Additionally, the mesh layer comprises a plurality of functionalized fibers, wherein one or more of the plurality of functionalized fibers break off from the mesh layer when impacted by one or more particulates. In some embodiments, a sand control screen assembly includes a screen layer with a functionalized coating.

First claim

What is claimed is:

1. A sand control screen assembly, comprising:
a base pipe comprising a tubular surface and a plurality of perforations formed in the tubular surface;
a mesh layer disposed around the base pipe, wherein the mesh layer comprises a plurality of brittle, chemically functionalized fibers, wherein at least a portion of at least one of the plurality of brittle, chemically functionalized fibers breaks off from the mesh layer when impacted by one or more particulates, wherein the plurality of brittle, chemically functionalized fibers are chemically modified with a functional organosilane so as to be detectable in a production fluid, and wherein the functional organosilane is chemically modified with one or more of fluoride, bromide, sulfur, phosphorous, and fluorescent organic molecules; and
a sand screen layer disposed around the mesh layer.

2. The sand control screen assembly of claim 1 , wherein the plurality of brittle, chemically functionalized fibers include a plurality of functionalized silicate fibers.

3. The sand control screen assembly of claim 1 , wherein the plurality of brittle, chemically functionalized fibers include a plurality of functionalized borosilicate fibers.

4. The sand control screen assembly of claim 1 , wherein the mesh layer comprises a first portion and a second portion, wherein the first portion of the mesh layer comprises a first type of functionalized fiber and the second portion of the mesh layer comprises a second type of functionalized fiber, and wherein the first type of functionalized fiber is distinguishable from the second type of functionalized fiber.

5. The sand control screen assembly of claim 4 , wherein the second portion of the mesh layer is disposed at a known depth of a well.

6. The sand control screen assembly of claim 1 , wherein the plurality of brittle, chemically functionalized fibers is detectable within the production fluid through a solid-phase analysis method or a liquid-phase analysis method.

7. The sand control screen assembly of claim 6 , wherein the solid-phase analysis method or liquid-phase analysis method include energy-dispersive x-ray spectroscopy or inductively coupled plasma mass spectroscopy.

8. A method of identifying erosive particulates in a reservoir, comprising:
recovering a production fluid from a well via a sand control device, the sand control device comprising a screen layer and a mesh layer disposed around a base pipe, wherein the mesh layer comprises a plurality of brittle, chemically functionalized fibers, wherein the plurality of brittle, chemically functionalized fibers are chemically modified with a functional organosilane, and wherein the functional organosilane is chemically modified with one or more of fluoride, bromide, sulfur, phosphorous, and fluorescent organic molecules, and wherein at least a portion of at least one of the plurality of brittle, chemically functionalized fibers breaks off from the mesh layer when impacted by one or more particulates;
determining, by a detector, the presence of the functional organosilane in the production fluid; and
determining, by the detector, a concentration of the functional organosilane.

9. The method of claim 8 , further comprising:
determining the presence of the functional organosilane through energy-dispersive x-ray spectroscopy.

10. The method of claim 8 , further comprising:
dissolving the functional organosilane in a carrier fluid; and
determining the presence of the functional organosilane through inductively coupled plasma spectroscopy.

11. The method of claim 8 , further comprising:
determining a concentration of a second functionalized material, wherein the sand control device comprises the second functionalized material.
