Abstract
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 to separation of brine from hydrocarbons, using enhanced diffusion to establish an upper limit for the T,spectral distribution of the brine. Parameters that can be modified to enhance the diffusion relaxation during the measurements include the interecho spacing T,and the magnetic field gradient G of the measurement tool.
