Molten Metal Manipulation
Rawwater Density Displacement
Primarily associated with Plugging & Abandonment, Rawwater Density Displacement exploits the capabilities of our extreme-performance, low melting point alloys to displace materials and/or substances of a lesser density, such as water. Once heated to melting point, the molten alloy searches out cracks, percolation pathways, secondary pathways (such as damaged annulus cement) and gaps caused through cement plug shrinkage, with expansion upon solidification to give a tenacious gas-tight seal.
The result of a £1 million development programme, we have produced a suite of proprietary expanding metal alloys for use as high integrity seals in oil well abandonment. Our alloy classes are suitable for onshore, offshore and subsea use, and have been subjected to strict technical qualification by Bureau Veritas – stipulated by DNV-RP-203 – Jul 2013, ISO 14310 (V0) and Oil & Gas UK, with an anticipated design life for plugs of 3,000 years.
