Quintessa Update
Welcome to the August 2000 edition of the Quintessa Update which provides a brief overview of some of our recent activities. Further information can be found at www.quintessa.org.
BGS - Quintessa Agreement
On the 4th July, Quintessa and the British Geological Survey signed a Memorandum of Understanding, agreeing to work together on commercial projects, particularly those relating to the geological disposal of toxic, hazardous, or radioactive wastes, and also on projects relating to hydrocarbon exploration and production....
MaTADoR - 2D flow and
transport simulator
To meet the need for accurate simulation of solute migration in groundwater, Quintessa has developed MaTADoR, a new 2D flow and transport simulator. Based on accurate mixed finite-element flow field solutions and non-uniform gridding techniques, MaTADoR can be utilised to simulate anisotropic heterogeneous and fractured regions at realistic spatial scales. At present, MaTADoR is being used in an attempt to understand the effect of connectivity of fractures in peak breakthrough flux calculations ....
CO2
Disposal
In recent months there has
been increasing interest in adapting performance
assessment approaches developed for radioactive waste
disposal to the underground storage of carbon dioxide, in
response to growing concerns about global warming. Please
see www.ieagreen.org.uk for up-to-date information on the
IEA Greenhouse Gas R&D Programme.
Quintessa is involved in a successful bid to
the European Community to study the potential for the sequestration of
CO2 in an oilfield employing enhanced oil recovery techniques at
Weyburn, Saskatchewan, Canada.

Quiz
Win a bottle of Quintessa Whisky
In 1770, Waring made the statement that every natural number (1, 2, 3, ...) can be expressed as the sum of at most 4 squares of natural numbers, 9 cubes of natural numbers, and so on. The statement was proved by Hilbert in 1909. In the special case of cubes, it turns out that most of the natural numbers can be expressed as the sum of at most 8 cubes. For example,
| 28 = 33 + 13 | |
| 60 = 33 + 33 + 13 + 13 + 13 + 13 + 13 + 13 |
The question is: Which numbers cannot be expressed as the sum of at most 8 cubes? The sender of the first correct reply received by e-mail will receive a bottle of Quintessa Whisky.
