Abstract
A system for sealing a region of open hole gravel pack comprising a sealing patch and an installation tool is described. The sealing patch includes a tubular assembly including two expandable anchor/seals and two low melting temperature alloy elements positioned on outside surface of the tubular assembly above the anchor/seals. The system is deployed in desirable location in the well and the tool is operated to set anchor/seals in interference contact with sand-screen. Then the alloy elements are melted to seal the patch. The anchor/seals serve two purposes: they provide a hanging capacity to support the patch in the well and create a 'bridge' preventing the molten alloy from freely flowing through the annulus between the tubular assembly and sand screen and focusing the molten alloy at the anchor/seals to flow in radial direction penetrating through the sand-screen and the surrounding proppant sand creating a complete seal.
