Study of Two Phase Fluid Flow in Water Wet Reservoir Rocks by Using X-Ray In situ Saturation Monitoring
Displacement of oil and water in porous media of reservoir rocks is described by relative permeability curves, which are important input data for reservoir performance simulation and drive mechanism studies. Many core studies, such as multiphase relative permeability, capillary pressure and saturation exponent determination, depend on the volume fractions of multiphase flui...
متن کاملX-Ray in-situ saturation monitoring, an aid to study relative permeability in water-wet carbonate rocks
The simultaneous flow of oil and water in porous media is described by relative permeability curves, mainly derived from laboratory experiments. Relative permeability is of paramount importance in predicting reservoir production performance and drive mechanisms and its value depends largely on the volume fraction of fluids present in the test samples. Nowadays X-ray scanners are one of the most...
متن کاملDiffuse X-ray scattering of amorphous multilayers
We present a new method to measure the difuse scattering of amorphous multilayers. In contrast to conventional scans, that all take place in the plane of reflection, in this out-of-plane scattering geometry the accessible range in parallel momentum transfer Qi is not limited by the sample surface. We can therefore record data continuously from
متن کاملRiboswitch conformations revealed by small-angle X-ray scattering.
Riboswitches are functional RNA molecules that control gene expression through conformational changes in response to small-molecule ligand binding. In addition, riboswitch 3D structure, like that of other RNA molecules, is dependent on cation-RNA interactions as the RNA backbone is highly negatively charged. Here, we show how small-angle X-ray scattering (SAXS) can be used to probe RNA conforma...
متن کاملStrain in a silicon-on-insulator nanostructure revealed by 3D x-ray Bragg ptychography
Progresses in the design of well-defined electronic band structure and dedicated functionalities rely on the high control of complex architectural device nano-scaled structures. This includes the challenging accurate description of strain fields in crystalline structures, which requires non invasive and three-dimensional (3D) imaging methods. Here, we demonstrate in details how x-ray Bragg ptyc...
