  • Method for Determining Rock Formation Fluid Interaction Properties Using Nuclear Magnetic Resonance Well Logging Measurements
    Publication number: 20130057277
    Abstract: A method for determining surface relaxivity of a rock formation in a wellbore includes using measurements of nuclear magnetic resonance properties of the rock formation made from within a wellbore penetrating the rock formations includes determining nuclear magnetic relaxation properties from the measurements of the nuclear magnetic resonance properties. A diffusion property of the rock formation is determined from the measurements of the nuclear magnetic resonance properties. The surface relaxivity of the rock formation is determined from the relaxation properties and the diffusion property. The surface relaxivity and other nuclear magnetic resonance properties are used to infer wettability and/or fluid saturation of the rock formations.
