Porosity

GEO101L Earth Science Module 3 Lab: Soil Porosity and Permeability Soils are made up of particles of rock, along with the spaces between those particles. Physical characteristics of soil particles, such as size and shape, can influence how water moves through them. Aquifers are underground layers of rock that are capable of storing water. An aquifer is recharged when water filters through the soil levels above it. In this lab you will investigate the characteristics of known and unknown soil

Depth. correlate the other surveys to this reference log or the Gamma ray curve from this log. 4. Select intervals with at least four feet of constant response whenever possible. Use a single representative value from the center of the zone for each porosity and resistivity measurement. This procedure minimizes thin bed and bed boundary effects on the logs. 5. Consider how to keep the interpretation simple. Analyse the most clear-cut cases first. Look for: The obvious mineral markers (salt, anhydrite)

concrete are affected by the manner in which the pores of various sizes are distributed within it. The porosity of concrete along with pore size distribution determine the performance of such materials in construction applications. The performance includes the mechanical properties such as strength and durability properties including the ingress of chloride and sulphate ions. The total porosity in the system has a noticeable effect on the mechanical properties of construction materials , whereas

According to the manufacturer, the type of SiC particles is green hexagonal, which means they are of the type α-SiC. Therefore, I think we need to look at the properties for this type of SiC only. Before this, for choosing the value of CTE for SiC, I used the room temperature values declared on Table 3 of the 1997 publication by R.G. Munro, which is attached to this message. For room temperature the value 1.1 and for 500°C the value 4.4 is given. I noticed that for all other experimental CTEs as

immediately beneath the petroleum is referred to as the bottom water, and the zone of the reservoir laterally adjacent to the trap as the edge zone. Gross pay is total thickness of the reservoir unit.Net pay is the fraction of the reservoir that has porosity

intrinsic flaw. The bulk density, apparent specific gravity and percent open porosity is shown in table (4). There was no significant difference between in the bulk density and apparent specific gravity of the samples. This shows that the amount of air in the samples are the same thought the quartz sizes. For the percent open porosity there is also a deviation from the 30 quartz size. Ignoring that size the amount of open porosity increases with the increase in quartz size. This makes sense given the fact

As stated previously, the objective of this porosity lab is to calculating the effective porosity of a core plug sample by measuring the bulk and grain densities. The effective porosites calculated for the core plug sample using various techniques did not show huge differences. After using the caliper to obtain five different diameters and three different lengths readings for the core plug sample at various locations, we were able to obtain an average diameter of 3.86cm3 and an avarage length of

of cement leads to formation of a network of hydrated solid product with the left empty spaces between the hydrated products that are occupied by water left after hydration. These residual spaces are known as capillary pores. The capillary porosity of the cement paste depends on the original water-cement ratio and on the amount of cement that has become hydrated. Capillary pores volume reduces with time by precipitation of hydrates, into originally water filled space. Capillary pores

current advances made in their application. It is also explained how porosity of the rocks are obtained from shaly formations using sonic logs. The principle of sonic logging involves a transmitter and a receiver wherein a signal is sent from the transmitter and the amount of time taken until it has reached the receiver is recorded. The speed of sound in the subsurface depends on the elastic properties of the rock matrix, the porosity of the formations, fluid content and pressure of the formation (Petroleum
