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.
Claims11
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.
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.
