Three days away from e-mail and this has got a bit big. I said on Friday I would jot down my thinkings and post it up, well its a bit big for the mail buffer, so I have put it into HTML format on the company web server. If anyone is inclined to read it, it's at http:\\www.epsedin.co.uk\text.htm. I'll leave it up their until the subject line stops evolving. The rest of the web site will probably not be that exciting, unless you have an interest in Petroleum Engineering.
