In the standard sequential interpretation process, the analyst determines porosity directly from the density log. It is conceptually the easiest of the porosity logs to interpret because, if ever a tool obeyed a linear bulk mixing law, it is the density logs.
WebApr 11, 2024 · A cell density higher than 1000 cells/in2 was found to be 32% more effective than a standard 900 cells/in2 substrate at controlling high space velocity, higher temperature ... WebMaterials with lower porosity tend to have higher density, while materials with higher porosity tend to have lower density. Understanding this relationship can be useful in a variety of contexts, including engineering, construction, geology, and environmental science.
WebNanoaluminum oxides reduce the bulk density and enhance the percentage of void spaces in soil (Taha and Taha, 2012). Soil porosity and bulk density are contrarily in proportion. NPs can affect pores ratio (micropores and macropores). NPs rich soils such as allophane and imogolite have low bulk density due to the high microporosity (Zhang, 2007). Webdirectly proportional to their bulk density, ρ bulk. The bulk density measured by the tool, ρ log, results from the combined effects of the fluid (porosity) and the rock (matrix) and is …
