| contents | <p>Laboratory 1H nuclear magnetic resonance (NMR) is a fast, reliable, and non-destructive method that is widely adopted in the oil industry. It allows the quantification and typification of organic solid matter and fluids in source rocks. Among the many constituents present in oil and gas reservoirs, the clay matrix content has been identified as a key contributing factor for reservoir quality evaluation. Correct quantification of clay bound water (CBW) gives insight on clay content and allows the determination of effective porosity. In conventional rock samples, 1D T2 measurements may be used to quantify CBW. In unconventional rocks the preferred methodology is a time consuming 2D T1-T2 relaxation map acquisition. In search of reducing measurement time, 1D T1 measurements are analyzed to derive a quantitative value of CBW. We aim to compare the different approaches taken to obtain CBW values and understand advantages and limitations of each method. 1D NMR results are directly compared to 2D NMR to validate the validity of each approach. Furthermore, clay content from XRD experiments is used to correlate measured CBW values. Results from 3 different wells from the Vaca Muerta Formation in the Neuquén basin of Argentina are shown.</p> |
