Use of Pressure Activated Sealant Technology to Cure Pipeline Leaks Technology Status Assessment Report DE-FC26-03NT41858 Michael A. Romano Seal-Tite International 500 Deer Cross Drive Madisonville, Louisiana 70447 October 31, 2003 Use of Pressure Activated Sealant Technology to Cure Pipeline Leaks Introduction Pressure activated sealant technology has been successfully and commercially applied in the oil and gas industry on a world-wide basis for over seven years. Over these years the capabilities of this technology has been substantially expanded to be able to cure leaks in a wide variety of equipment in a broad range of conditions, including applications in subsea gathering lines and pipeline applications in South America. This technology is unique in that a pressure drop through a leak site causes the sealant fluid to polymerize into a flexible solid seal only at the leak site.
