<p>A method for conducting borehole NMR measurements comprising the steps of providing a magnetic field and a magnetic field gradient (G) at a desired location along a borehole (107); carrying out at least one NMR experiment in the presence of the magnetic field gradient (G); sensing the diffusion effect on the decay of at least the first echo; and determining therefrom the diffusion coefficient (32).</p> |
