... sandstone cores with approximately 10% porosity after shielding the hydrogen signal and altering the wettability of nano-emulsion. The oil saturation of the core was calculated under different imbibition displacement times, and the T2 spectrum at various times was analyzed to determine the distribution...

... on the frequency shifts of the Rayleigh backscattered spectrum, which is sensitive to temperature and mechanical strain changes. This work uses in-well RFS-based DSS and DTS measurements acquired during a single-stage stimulation. The goal is to quantify the mechanical strain changes by removing the temperature...

... and fast measurements, which only need a small amount of sample, to evaluate the maturity of organic matter (Beyssac, 2002; Quirico, 2005; Lahfid, 2010; Guedes, 2010; Hinrichs, 2014; Wilkins, 2014). The Raman spectrum of organic matter consists of the disordered (D) band and the graphite (G) band. The G...

... signals from solid matrix can be easily detected in high field. For example, NMR at 600 MHz is about 5,000 times more sensitive than the NMR at 2 MHz. Meanwhile, the spectral resolution of high-field NMR is also greatly increased and high-field NMR spectrum can resolve the detailed differences between...

... (ASTM D7708) and confocal laser-scanning Raman microscopy. For RM, multiple hyperspectral maps were collected from each sample, resulting in tens of thousands of spectra per sample. Map areas were ~5,000 μm 2 , with a spectrum collected from every square micrometer. The organic carbon G- (Graphitic...

... at this conference. For the Phase-II study, solid bitumen reflectance (B Ro ) values for the Duvernay series will be known. Multiple hyperspectral maps were collected from each Bakken sample, with each map consisting of a single diffraction-limited spot-size spectrum per 1 μm 2 in rectangular areas several hundred...

... alternative is spectroscopy, the deduction of TOC from interactions of light of a certain wavelength with the source rock, which is rapid, non-destructive, and potentially requires minimal sample preparation. In geosciences, two regions of the electromagnetic spectrum are used for quantifying the abundance...

... of fractures can be critical in positioning drilling locations. Fluid-filled fractures and cracks directly modify the effective impedance of rocks, attenuate amplitude and distort seismic spectrum. Thus, attenuation estimation is a promising way to characterize fracture system. Existing methods for seismic...
