Arcasolve to be Featured in Millennium Dome

Arcasolve(TM) will be one of the Millennium Products to be featured on the Spiral of Innovation situated above the Millennium Domes Meridian Quarter.

Arcasolve is a patented and highly effective method of acidizing oil and gas wells in which acid is generated in-situ using enzyme catalysts. In-situ generation ensures excellent zonal coverage. The process has particular application in the removal of drilling fluid damage, deep matrix acidising and the stimulation of fracture networks as well as other acidizing applications.

Cleansorb Directors Ralph Harris and Ian McKay were present at the announcement of the fifth and final tranche of Millennium Products which took place at the Dome Complex on 14th December and included speeches from John Sorrell, Chairman of the Design Council and the Prime Minister Tony Blair.

Notes to Editors:

1. British Prime Minister Tony Blair Launched the Millennium Products Initiative in September 1997 to identify and promote the most innovative products, designs and services which will change the way we live in the 21st century. Selection criteria include innovation, creativity and whether the product is pioneering in its field.

2. Arcasolve was awarded Millennium Products status during the second tranche in November 1998. A total of 1,012 products have now been granted Millennium Products status, ranging from the Airbus A340-500/-600 wing to a simple water purification system for use in emergency situations and from needleless injection systems to anti-counterfeiting systems.

3. All Millennium Products have had to meet strict criteria, proving in front of selected panels of highly regarded business leaders, scientists, designers and social commentators that they:
· open up new opportunities
· challenge existing conventions
· are environmentally responsible
· demonstrate the application of new or existing technology
· show clear user benefits
