  • Method for determining formation particle size distribution using well logging measurements
    Patent number: 8653815
    Abstract: A method for determining particle size distribution of a subsurface rock formation using measurements of at least one nuclear magnetic resonance property made from within a wellbore penetrating the rock formation includes determining a distribution of nuclear magnetic relaxation times from the measurements of the at least one nuclear magnetic resonance property. A surface relaxivity of the formation is determined from measurements of a formation parameter. The relaxation time distribution and surface relaxivity are used to determine the particle size distribution.
    Type: Grant
