Temperature-Dependent Oxygen Effect on NMR D-$$T_2$$ Relaxation-Diffusion Correlation of n-Alkanes
Abstract Nuclear magnetic resonance (NMR) diffusion-relaxation correlation experiments (D-$$T_2$$) are widely used for the petrophysical characterisation of rocks saturated with petroleum fluids both in situ and for laboratory analyses. The encoding for both diffusion and relaxation offers increased...

| 520 | |a Abstract Nuclear magnetic resonance (NMR) diffusion-relaxation correlation experiments (D-$$T_2$$) are widely used for the petrophysical characterisation of rocks saturated with petroleum fluids both in situ and for laboratory analyses. The encoding for both diffusion and relaxation offers increased fluid typing contrast by discriminating fluids based on their self-diffusion coefficients, while relaxation times provide information about the interaction of solid and fluid phases and associated confinement geometry (if NMR responses of pure fluids at particular temperature and pressure are known). Petrophysical interpretation of D-$$T_2$$ correlation maps is typically assisted by the “standard alkane line”—a relaxation-diffusion correlation valid for pure normal alkanes and their mixtures in the absence of restrictions to diffusing molecules and effects of internal gradients. This correlation assumes fluids are free from paramagnetic impurities. In situations where fluid samples cannot be maintained at air-free state the diffusion-relaxation response of fluids shift towards shorter relaxation times due to oxygen paramagnetic relaxation enhancement. Interpretation of such a response using the “standard alkane line” would be erroneous and is further complicated by the temperature-dependence of oxygen solubility for each component of the alkane mixture. We propose a diffusion-relaxation correlation suitable for interpretation of low-field NMR D-$$T_2$$ responses of normal alkanes and their mixtures saturating rocks over a broad temperature range, in equilibrium with atmospheric air. We review and where necessary revise existing viscosity-relaxation correlations. Findings are applied to diffusion-relaxation dependencies taking into account the temperature dependence of oxygen solubility and solvent vapour pressure. The effect is demonstrated on a partially saturated carbonate rock. | ||

Petrophysical interpretation of D-$$T_2$$ correlation maps is typically assisted by the “standard alkane line”—a relaxation-diffusion correlation valid for pure normal alkanes and their mixtures in the absence of restrictions to diffusing molecules and effects of internal gradients. This correlation assumes fluids are free from paramagnetic impurities. In situations where fluid samples cannot be maintained at air-free state the diffusion-relaxation response of fluids shift towards shorter relaxation times due to oxygen paramagnetic relaxation enhancement. Interpretation of such a response using the “standard alkane line” would be erroneous and is further complicated by the temperature-dependence of oxygen solubility for each component of the alkane mixture. We propose a diffusion-relaxation correlation suitable for interpretation of low-field NMR D-$$T_2$$ responses of normal alkanes and their mixtures saturating rocks over a broad temperature range, in equilibrium with atmospheric air. We review and where necessary revise existing viscosity-relaxation correlations. Findings are applied to diffusion-relaxation dependencies taking into account the temperature dependence of oxygen solubility and solvent vapour pressure. The effect is demonstrated on a partially saturated carbonate rock.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Nuclear Magnetic Resonance</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Alkane</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Normal Alkane</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Nuclear Magnetic Resonance Relaxation</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Paramagnetic Relaxation Enhancement</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Arns, Christoph H.</subfield><subfield code="0">(orcid)0000-0003-1721-3996</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Applied magnetic resonance</subfield><subfield code="d">Springer Vienna, 1990</subfield><subfield code="g">47(2016), 12 vom: 19.

Temperature-Dependent Oxygen Effect on NMR D-$$T_2$$ Relaxation-Diffusion Correlation of n-Alkanes |
| abstract |
Abstract Nuclear magnetic resonance (NMR) diffusion-relaxation correlation experiments (D-$$T_2$$) are widely used for the petrophysical characterisation of rocks saturated with petroleum fluids both in situ and for laboratory analyses. The encoding for both diffusion and relaxation offers increased fluid typing contrast by discriminating fluids based on their self-diffusion coefficients, while relaxation times provide information about the interaction of solid and fluid phases and associated confinement geometry (if NMR responses of pure fluids at particular temperature and pressure are known). Petrophysical interpretation of D-$$T_2$$ correlation maps is typically assisted by the “standard alkane line”—a relaxation-diffusion correlation valid for pure normal alkanes and their mixtures in the absence of restrictions to diffusing molecules and effects of internal gradients. This correlation assumes fluids are free from paramagnetic impurities. In situations where fluid samples cannot be maintained at air-free state the diffusion-relaxation response of fluids shift towards shorter relaxation times due to oxygen paramagnetic relaxation enhancement. Interpretation of such a response using the “standard alkane line” would be erroneous and is further complicated by the temperature-dependence of oxygen solubility for each component of the alkane mixture. We propose a diffusion-relaxation correlation suitable for interpretation of low-field NMR D-$$T_2$$ responses of normal alkanes and their mixtures saturating rocks over a broad temperature range, in equilibrium with atmospheric air. We review and where necessary revise existing viscosity-relaxation correlations. Findings are applied to diffusion-relaxation dependencies taking into account the temperature dependence of oxygen solubility and solvent vapour pressure.
