.... We considered dynamic models with both structural and unstructral grids to understand the impact of these in modelling production transient effects. The structural grid simulations used 100m by 100m gridcells with dual porosity, while the unstrucutral grids were built using a single porosity (SP...

.... The porosity partioning was obtained from NMR data. A detailed mineralogy and organic content were obtained from the geochemical spectroscopy logging. The most relevant results of the petrophysical analysis in this work was to improve fluid saturation analysis using OSP. Kerogen identified with the OSP...

... was used in a real-time application with downhole drilling data. The gamma-ray, neutron porosity, density and resistivity were analyzed and compared with the MSE obtained. Drilling efficiency was assumed based on prescribed industry standards for calculating confined compressive strength (CCS), Internal...

... ). With the above measurements, porosity, mineralogy and images can then be integrated for applications such as enhanced geosteering in challenging environments. Measure porosity and grain density of the core plugs using gas pycnometry on dry samples and NMR on 100% water saturated samples to help to create...

... Finally, the segmented images were used to calculate a percentage from the number of pixels of each component, N i , relative to the total number of pixels in the image, N t . As such, the percent porosity, ϕ SEM , is calculated as shown in Eq. 1 . The organic content from SEM can...
