Porosity and Permeability Lab Worksheet.pdf - POROSITY - Course …

WebIf compaction increases bulk density from 1.3 to 1.5 g/cm 3, porosity decreases from 50 percent to 43 percent. Aggregation also decreases porosity because more large pores are … WebThe "density porosity" of the granite has no immediate meaning, scaled as it is to a limestone-porosity system. However, a simple backcalculation of the bulk density measurement gives an estimated density of about 2.6 gm/cc. A more extensive discussion of log properties will be made in the section on Igneous and Metamorphic Rocks. can i pay a texas dps ticket online

Density and Porosity (Chapter 2) - Fundamentals of Rock …

WebA second method, the Resaturation Method, uses a clean dry core sample and resaturates it with a fluid of known density.The change in weight of the sample can then be used to determine the pore volume, V p, of the sample. Since the fluid can only enter or leave the connected pores, the porosity obtained from the resaturation method is the effective … WebThe total density (bulk density) of the formation is an average of densities of the matrix and fluids in the pores of the mud-fluid flushed zone, and the porosity is affected by the presence of shale. The density of shale varies between 2.20 and 2.85 g/cm 3, depending on the types of clay minerals in the shale. WebThe porosity reflects "free" water in the sandstones, but bound water in the shales. The density log is a measure of apparent density of the rock and is computed from the absorption of gamma rays emitted from a tool radioactive source by the formation. An example of a density log run in the Dakota is shown in Figure 5. can i pay a marketer to market my property
