A novel method and system is disclosed for the separation of fluid phases in NMR borehole measurements. The method is based on forcing diffusion as the dominant relaxation mechanism for certain fluid phase by adjusting certain user controlled parameters. The invention is more specifically applicable...http://www.google.de/patents/US6316940?utm_source=gb-gplus-sharePatent US6316940 - System and method for identification of hydrocarbons using enhanced diffusion
