Web(xiv) Vug porosity Porosity associated with vugs, commonly in carbonate rocks. It should be noted that if the bulk volume and dry weight, or the bulk volume, saturated weight and porosity of a rock sample is known, then the grain density can be calculated. This parameter is commonly calculated from the data to compare the results with the known ... WebJan 1, 2024 · a) Comparison of MAD total porosity measured on cores at Site U1481 and porosity calculated from resistivity log at Site U1481 (sliding average for 10 resistivity values). b) Fracture porosity calculated from formation bulk conductivity, interstitial fluid conductivity and the conductivity of rock fragments at Site U1481.

WebFeb 6, 2024 · The porosity, φ is calculated as ratio of the volume of void space to the the total volume of a material φ = V v o i d V t o t, and is usually expressed as a fraction between 0 and 1 or as a percent. Note that if φ ≤ 1 then … WebFeb 22, 2024 · 5. Set up the equation to solve for porosity with volume. Now that you have the volume of your sample () and the pore volume ( ), you can add them together to get total volume ( ). It is now possible to use the equation = ( /) x 100% to find your porosity ( ). [9] 6. Do the calculations to find your sample’s porosity. WebThe porosity is usually an isotropic property (i.e. the same in all directions); hence, the interstitial velocity is simply related to the superficial velocity by the following expression, which comes from a consideration of fluid continuity. ε U = Uo (3.1) Clearly, the resistance to fluid flow through the porous medium is other another the other others练习题
