Total (absolute) Porosity and Isolated Porosity MeasurementRaboon Redar
Absolute porosity is the percentage or volume of void spaces or porosity of rocks that can contain hydrocarbons. Porosity is the measure of a rock’s ability to hold hydrocarbons like oil and gas, water, and condensates. Absolute porosity contains effective (interconnected) and ineffective (isolated) porosity. Effective porosity is the volume of connected pores, but isolate is the pore volume which is not connected to the pore network. Isolated porosity can be significant in volcanic rocks and some carbonates.

Lab 2 - Soil Texture, Density, and Porosity
Introduction
Soil physical properties greatly impact how soils behave. Outcomes of most agricultural as well
as engineering projects are often defined by the properties of the soil involved. Soils are made
of soil solids and pore space; the soil solids are made up mostly of minerals as well as organic
matter while the pore space is made up of air and water. Ideally, these two portions are in a
50/50 ratio (Figure 1). Soil physical properties describe the soil particles and the manner in
which they aggregate and are arranged. The following exercise will focus on soil texture, soil
density, and soil porosity.
Figure 1. Ideal soil composition (Text Figure 1.18)
Soil Texture
Soil texture is the proportion of the different sized particles in soil. Only the fine earth fraction
of sand, silt, and clay are included. There are two methods for determining texture in soils by
feel and mechanistically using particle size analysis. Neither the coarse fraction greater than
2mm in diameter nor organic matter are included in textural analysis. In the previous lab
exercise, soil texture was estimated by feel. The particle size analysis procedure via mechanical
means is accomplished using a Bouyoucos hydrometer and calculated using Stokes Law. Stokes
law establishes a relationship between particle size and sedimentation. The velocity by which a
particle fall through a liquid is proportional to the gravitational force and the square of the
effective particle diameter. In other words, ‘the bigger they are, the faster they fall’. When
the soil is dispersed, the larger, sand particles will settle or fall to the bottom of a liquid faster
than silts or clays.
When conducting this experiment in the lab, the first task it to remove the coarse fraction from
the soil sample which is generally done by sieving (2mm). Soil particles want to stay together;
the soil separates and their aggregates do not easily separate. In order to achieve separation
both mechanical and chemical intervention is needed. Sieving removed large portions of the
organic matter, but it still is a significant agent in the binding of soil particles together, so
hydrogen peroxide is al ...
Porosity is the quality of being porous, or full of tiny holes. Liquids go right through things that have porosity. It is shown as a fraction of the volume of voids over the total volume, which is between 0 and 1, or between 0% and 100% as a percentage. Primary and secondary porosity can be read directly from neutron, density, and sonic logs.

3. Defination:
The ratio of the pore volume in a rock
to the bulk volume of that rock.
Denoted by φ.
Express in Percent.
Mathematical Form: φ = Vp/Vb
6. Types of porosity
There are two types of porosity
1) Primary porosity
2) Secondry porosity
1) Primary porosity
The porosity of the rock that formed at the time of its deposition.
2) Secondry porosity
Develops after deposition of the rock.
For example:
Fracture spaces formed in fractured reservoirs
7. Further types of porosity
They are further subdivided into
1) Total porosity
2) Effective porosity
3) Microporosity
4) Mesoporosity
5) Macroporosity
1) Total Porosity
The ratio of the entire pore space in a rock to its bulk volume.
2) Effective Porosity
The measure of the void space that is filled by recoverable oil and gas
φ = Vol. of interconnected pores + Vol. of deadend
Total or bulk vol. of reservoir rock
In very pure sandstone Total porosity is equal to Effective porosity
8. 3) Microporosity
In solids , the term 'microporosity' refers to pores smaller than 2 nm
in diameter.
4) Mesoporosity
In solids , the term 'mesoporosity' refers to pores greater than 2 nm
and less than 50 nm in diameter.
5) Macroporosity
In solids , the term 'macroporosity' refers to pores greater than 50
nm in diameter.
9. Determination of Porosity
1) Direct method
2) Water evaporation method
1) Direct methods
Determining the bulk volume of the porous sample, and then
determining the volume of the skeletal material with no pores .
pore volume = total volume − material volume.
2)Water evaporation method
pore volume = weight of saturated sample − weight of dried
sample)/density of water
