I received a list of ILL requests from one of our engineers. He asked for a Gas Research Institute publication and a number of Society of Petroleum Engineers papers. I've been able to locate some of these papers, but some of them are "stubborn." These conference papers aren't widely held, and some are not available via OCLC and/or available in the USA. I'm hoping that someone can provide them.
